Toilet Bowl will not fill after the Flush

Toilets that do not refill the bowl after the flush are mainly a fill valve issue. Here are some simple solutions that you can try to fix this problem.

  1. Check that the refill tube is attached to the top of the overflow pipe
  2. Check Bowl Refill adjustments are set properly for water dispensing into bowl after a flush
  3. Flushing Debris from fill valve
  4. Replace / repair the fill valve

 A. The Refill Tube delivers water directly to the toilet bowl with every flush. Make sure the tube is dispensing water directly into the overflow pipe. The refill tube needs to be set on a clip set above the pipe and not shoved directly inside the pipe or a siphon will occur, causing the toilet to turn on and off like a ghost flush.

B) The Fluidmaster 400H-002 fill valve has a Bowl Refill Knob that lets more or less water go into the bowl – if you are using a 400H-002 from Fluidmaster make sure this adjustment is set properly.

 

C. Flushing debris from your water supply and fill valve:

Toilet Running Constantly

When your toilet keeps running water or is constantly running, we must first find out if you have a fill valve issue or a flapper/flush valve issue.

Step 1 – If you have shut off the water supply line, then turn on water and look inside the tank. Determine if the water level is rising so high it is draining into the overflow pipe. If the answer is yes then follow the steps for cleaning the fill valve.

Step 1A – If flushing debris (Cleaning Solution) does not resolve the issue; Replace the fill valve. We recommend installing the 400H PerforMAX toilet fill valve.

Flushing Debris (Cleaning Solution):

It is possible for dirt and debris to lodge itself inside the valve. This can happen any time the water is on and may happen after a new installation, a few days later or even months and years after installation.

Follow these steps to clean the valve:

Turn off water and flush the toilet.

Reach into the tank with your right hand and lift up the float cup and grip the gray shaft and hold it in that position (see photo below).

Fix Running Toilet

With your left hand grab the cap and at the same time place your thumb on the side of the plastic arm.

Twist both the cap and plastic arm counterclockwise 1/8th turn. Press down on the cap while making a quick twisting motion.

Lift up on cap and move away from top of valve body. Using a cup hold the cup upside down over the exposed opening of the valve and turn on the water supply full force for 10-15 seconds. Look inside valve to ensure no debris is left inside the valve.

Reverse steps to place top back on the valve. Turn on water and flush toilet to ensure problem has been resolved.

Video: How to Fix a Running toilet

If this procedure does not resolve the issue then replacing the fill valve should resolve the issue. We recommend using the 400H PerforMAX toilet fill valve.

Step 2 –With the tank full of water turn off the water to the toilet and mark the current water level inside the tank. Wait a period of time 10-15 minutes and note if the water is draining down from your mark. If it drains down replace the flapper first as this is the most common problem. To determine whether you need a 2″ or 3″ flapper, please click here: Determine size of flapper

If you need a 2″ toilet flapper, we recommend the 502 toilet flapper

If you need a 3″ toilet flapper, we recommend either the 513A toilet flapper or the 5403 toilet flapper

Step 3– If you replace the flapper and the toilet continues to drain down (repeat step 2 if necessary) then we recommend replacing the flush valve as this will ultimately stop the constant draining of water from the tank to the bowl. We recommend the K-507A-008 flush valve if you have a 2″ toilet or the 540AKR flush valve if you have a 3″ toilet. To view all the flush valves, please click here: Flush Valves

Step 4 – If at any time the toilet keeps running water and you see water on the floor immediately turn off water and look inside the tank to see if the water is coming from the lid or tank lever area. Replace fill valve and replace flush valve. The flush valve is set to the wrong height or may be blocking the path of the water to drain safely into the toilet bowl.  If water is draining down and water is coming out from the bottom of the tank change tank bolts and washers.

If you need to replace any of the toilet parts, why not get Fluidmaster’s Everything Kit includes everything you need to fix your toilet in one purchase?

Testing The Toilet Tank Water For A Leak Into The Toilet Bowl

Leak Detector Tablets or food coloring can be used in a tank to confirm a leak but these tablets do not verify where the leak is occurring. The best troubleshooting procedure for determining the leak point is using this water test.

WATER TEST

  1. With a full tank, turn the water off at the shut of valve. DO NOT flush the toilet.
  2. Make a mark in the tank at the current water level.
  3. Wait 30 minutes. If the water level has dropped make a new mark at the new water level and continue to wait.
  4. Repeat step 3 until the water level no longer changes.

READING THE WATER LEVEL WITH SIMPLE SOLUTIONS

The water level will drop down to the level of the leak and stop.

  1. Water drains to the lip of the flapper –

A) The flapper may be worn.

B) The drain seat that the flapper rests on is damaged.

Recommended Solution A:  Change flapper. To determine whether you need a 2″ or 3″ toilet flapper, please click here: Determine size of flapper

If you need a 2″ toilet flapper, we recommend the 502 toilet flapper

If you need a 3″ toilet flapper, we recommend either the 513A toilet flapper or the 5403 toilet flapper

Recommended Solution B:  Repair flush valve drain

Please watch this video to see how to repair the flush valve drain:

 

2. The water drains to the bottom of the tank – This happens when the gasket that seals the flush valve into the tank is deteriorated and worn.

Recommended Solution: Change flush valve.

  • If a leak occurs at a flush valve gasket in new installation, the lock nut securing the flush valve to the underside maybe leaking. Fluidmaster instructs that the flush valve lock nut should be tightened no more than 1/2 turn beyond hand tight.

3. The water drains down 1/4 to 1/2 inch from your mark and stops.

A) The refill tubing may be positioned incorrectly.

B) The overflow pipe may have a crack.

Solution A: Re-position refill tube so it does not enter into the overflow pipe – if possible attach tubing to a clip to hold refill tube above pipe opening.

Solution B: Change flush valve. We recommend the K-507A-008 toilet flush valve

If you need to replace any of the toilet parts, why not get Fluidmaster’s Everything Kit includes everything you need to fix your toilet in one purchase?

If you are in the U.S. and have a 2″ flush valve toilet, we recommend the 2″ Everything Kit

If you are in the U.S. and have a 3″ flush valve toilet, we recommend the 3″ Everything Kit

If you are in Canada and have a 2″ flush valve toilet, we recommend the 2″ Everything Kit

If you are in Canada and have a 3″ flush valve toilet, we recommend both the 540AKR Flush Valve and the 400H Fill Valve

How to check your toilet's flush volume

Knowing how much your toilet flushes and which valves to use with them can be a complicated business. This article will help determine what valves are best used with your toilets. The easiest way to determine a toilet gallon per flush volume and which valve to use is by looking at the date of the toilet and looking at your toilets flush valve system. Use this date method to find the parts recommended.

  • Pre – 1994
  • 1994 – Present
  • 2005 – Present (HET- High Efficiency Toilets)

Pre-1994 Toilets Water Saving and older toilets:

Toilets that date prior to 1994 fall in to two main flush volumes: 5-7 gallon per flush (gpf) and 3.5 gallons per flush (gpf). In these toilets, Fluidmaster recommends using our Standard or Leak Prevention Fill Valves (400A or 400A with Brass Shank  or 400LSR) and a 2 inch (Non-Adjustable) Flappers (models include 500, 501, 503, 504).

1994  to 2006 Toilets:

Toilets that are dated 1994 to present time fall into two main flush volumes, 1.6 and 1.28 gallons per flush.

In these toilets, Fluidmaster recommends using both our High Performance Fill Valves (Model 400AH) or (Model 400H) our PerforMax® and Water Savings (Adjustable) Flappers both in 2 and 3 inch (sizing) categories (models include 502, 5051 and 5403).

2005 – Present (High Efficiency Toilets):

Toilets that are dated 2005 to present time fall into two main flush volumes, 1.28 and lower gallons per flush.

In these toilets,  Fluidmaster recommends using both our High Performance Fill Valves (Model 400AH) or (Model 400H)–  PerforMax® and Water Savings (Adjustable) Flappers – both 2 and 3 inch (sizing) categories –  3 inch Flush Valve (model 540AKR).

HET is an abbreviation for High Efficiency Toilet. These toilets have flush volumes that are less than the standard 1.6 gallon per flush toilet. These toilets need a higher refill rate when refilling the toilet bowl and may come with a larger than standard 2 inch flush valve drain.

Flush valves can be designed as Dual Flush, Tower Flush, 2 inch and 3 inch Flush Valve Drains.

  • Dual Flush valves can alternate the flush volume from a full flush (standard flush volume of 1.6 or less) to a partial flush (less than standard full flush). Fluidmaster  has a Dual Flush which converts “any” standard flush to an alternating flush using our dual flush technology (models 550DFRK & 550DFR)
  • Tower flush valves are valves that normally are 1 piece in design and the entire flush valve drain lifts up to release the water.
  • 2 inch and 3 inch Flush Valves are valves that flush using a flapper valve to release the water. The designation 2 inch and 3 inch describe the drain opening along with the corresponding size of the flapper that covers the drain opening. If you are unsure whether you have a 2″ or 3″ flush valve, please click here: Determine size of flush valve

Toilet Tank Won't Fill Up Or Is Slow To Fill

The main reason for a toilet tank not filling or filling slowly is due to the toilet fill valve. The most common reasons for the fill valve to slow down or no longer fill the tank after the flush are debris issues and the length of time a fill valve has been in use.

Debris that builds up over time inside the water system, including the valve body, supply line or shut off valve (at the wall) can restrict the flow path of water and slow down the valves filling speed.

Toilet fill valves in use for a period of 7 years or more can have their working parts start to wear out.

1. Read more for instructions on how to flush debris from your water supply or watch our instructional video:

2. You can also read more below if you are looking for repair parts or replacement valves.

Flushing debris from your water supply:

Fluidmaster recommends flushing debris out of the valve / water system first in order to resolve the issue.

Steps for removing the top cap and flushing out debris from the fill valve:

  1. Turn off water supply and flush the tank.
  2. Reach inside the tank with your right hand under the float cup and lift it up. With your right hand hold onto the gray shaft keeping the float cup all the way up. Do not allow the float cup to drop or valve shaft to turn.
  3. Place your left hand on the top of the valve cap and while placing your left hand thumb on the side of the arm coming out of the top. Turn the cap and lever counter clockwise 1/8th of a turn to unlock. You should be able to lift off the cap and lever from the valve body.
  4. Once the cap assembly has been removed inspect for debris on the seal (rubber disc with pin coming through) and also the valve portion still in the tank.
  5. Hold a cup upside down over the exposed opening of the valve and turn on the water supply full force for 10-15 seconds, allowing the pressure to free any debris inside the valve inlet.
  6. Reassemble the top of the valve by placing the cap arm next to the refill tube. To lock, press the cap down while turning it and the arm clockwise.

The bottom hand is lifting up on the float cup, which raises the black arm under the top cap. The top hand is gripping the cap while the thumb is pressing on the raised lever arm.

Here is a video on how to remove and replace cap assembly of the 400A fill valve:

2. Repair parts and replacement toilet fil valves:

When flushing debris does not seem to correct the next step is to repair or replace the valve. Fluidmaster Repair Parts and Fill Valves are available at most local retailers and we recommend genuine replacement parts. Repair Models sold:

Solutions for too much water in the toilet bowl

Fluidmaster fill valves are UPC (Universal Plumbing Code) certified and are designed to dispense water through the refill tube to the overflow pipe. This refill supplies water to the bowl during the filling cycle and is used to refill the water spot that is needed for the next flush. Fluidmaster uses a Roller Clamp device to control water going into the toilet bowl

Read below if you want information on:

1. How to check if the toilet bowl is overfilling with water or to adjust the Roller Clamp.

2. Toilets that do not require refill water into the bowl.

1. Toilet Bowl Test: Check bowl water level by flushing toilet. If bowl appears to be full but continues to fill, the valve may be overfilling the bowl causing excess water to siphon down the trap way. Adjust the amount of water going into the bowl by using these steps:

  1. Fill the bowl with a gallon of water. Wait 1 minute until the bowl water level recedes down and stops.
  2. With a pencil, draw a line at the top of the water level in bowl. Now flush the toilet.
  3. If the valve is still filling and the water is up to the line in the bowl, then the amount of water going into the bowl is too high and needs to be adjusted.

Adjusting the Roller Clamp: Watch this video

Or follow these instructions for adjusting the Roller Clamp:

  1. Adjust the Roller Clamp by pushing down and rolling the pin forward.
  2. Engaging the Rolling Clamp restricts the flow of water to the bowl. Repeat this action until the toilet bowl fills to your pencil mark at approximately the same time the tank water turns off.
  3. The “0” setting means that you have completely turned off the refill hose and no water is filling the toilet bowl.

2. Non-Required refill toilets: For toilets that do not require refill water to the bowl, Fluidmaster recommends using our model 215 Water Savings Roller Clamp with Refill Tube that comes with Hose Clamps.

If you do not have a Roller Clamp device, redirect the refill tube to the overflow pipe so that the water flows back into the tank.

CAUTION: If you do not have Hose Clamps on your refill tube, do not squeeze the tube shut completely. This will cause the refill hose to blow off from fill or flush valve connection.

Choosing the right flapper for your toilet

Selecting the right flapper for your toilet is very important since the flapper valve is what regulates the water to the bowl. Fluidmaster has developed a universal design set of flappers to help stop the confusion and select the right flapper. The flapper valves we offer are categorized by Frame, Size and Type.

If you are unsure what size of flapper you will need for your toilet, please click here: Determine size of flapper

Read below to learn more about:

1. Frame: Two styles of flappers

2. Size: The actual size of the flapper ball and which size of drain it will seal properly.

3. Type: The flushing capacity, which is the amount of water used to flush the toilet bowl, that the toilet was designed to use.

4. Keys to selecting a flapper

5. Fluidmaster flappers available

1. Frames: Fluidmaster currently has two styles of flappers

  1. Flexible Frame (All- Rubber): These flappers will fit most Flush Valve Drains and the all rubber-style flappers can stretch to fit oddly sized flush valves, angled seated flush valves and flush valves that do not have mounting posts for a fixed attachment.
  2. Solid Frame (Hard Plastic Frame): The plastic frame forces the flapper ball to consistently center onto the drain to seal every time. Solid Framed Flappers are designed to stop toilets from leaking for longer periods of time. This flapper style does not work with all Flush Valve Drains; however, the key to using this one is to know what you are currently using. There is a good chance that if you are using a plastic framed flapper already then the Solid Frame can be used as a replacement.

2. Size: Currently Fluidmaster offers two sizes of flappers for the two most common size Flush Valve Drains, 2-inch drains and 3-inch drains.

  1. 2-inch flappers are available in both styles: Flexible and Solid Frame.
  2. 3-inch flappers are only available in the Solid Frame style.

3. Types: There are two types of flappers, Adjustable Flappers and Non-Adjustable Flappers, and these flappers are designed for specific flushing capacities of toilets. There are 4 main toilet flushing capacities that are commonly used in the United States today; 5 gallon per flush and larger; 3.5 gallon per flush; 1.6 gallon per flush and 1.28 gallon per flush toilets.

  1. Toilets that are manufactured from 1994 to present come in both styles and in both size categories; Adjustable flappers are designed to flush toilets that flush 1.28 and 1.6 gallon per flush (GPF) toilets.
  2. Toilets that were manufactured before 1994 are all considered to be the larger gallon per flush toilets and are still in use. Non-Adjustable Flappers are designed to flush toilets that flush 3.5, 5 and larger gallon per flush (GPF) toilets. Non Adjustable Flappers come in both Styles but only in 1 size category, 2-inch.

To learn more about your toilet’s flush volume, please click here:

Determining your toilet type

4. Keys to understanding how to select a flapper can be as easy as:

  1. Know the age of your toilet (if you don’t know, guess the age of the home).
  2. Know if the flapper has a Solid Frame or if it’s a Flexible Frame.
  3. Know the size of your flapper, 2- or 3-inch (measuring the drain hole your flapper covers will tell you the size you need).

5. If you need a 2″ toilet flapper, we recommend the 502 toilet flapper

If you need a 3″ toilet flapper, we recommend either the 513A toilet flapper or the 5403 toilet flapper

Here are some examples of the Fluidmaster flappers available.

“I didn’t know my toilet could look this good without scrubbing”….says an independent review of Flush ‘n Sparkle on Architectural Digest

We know that keeping your toilet clean is important not just for aesthetics, but also for maintaining a healthy home. That’s why we’re excited to share with you an easy and effective way to keep your toilet bowl clean.

First off, let’s talk about why it’s so important to keep your toilet bowl clean. Over time, mineral buildup and bacteria can accumulate, leading to unpleasant odors, stains, and even potential health risks. One of the most effective ways to keep your toilet bowl clean is by using a quality toilet cleaner. Fluidmaster’s Flush ‘n Sparkle™ cleaning system is a great option, as it provides a powerful cleaning solution with every flush. Simply replace your traditional toilet bowl cleaner with the Flush ‘n Sparkle™ system and let it do the work for you.

Unlike drop-in bleach tablets, Flush ‘n Sparkle™ does not fill up the toilet tank with bleach as it is kept in a reservoir and hence does not destroy the toilet parts. The bleach from Flush ‘n Sparkle™ goes directly into the bowl keeping it sparkling clean. Now you can protect your flapper and other toilet parts by switching to Flush ‘n Sparkle™ that gives you scrub-free, hands-free cleaning up to 3 months.

Jeff from Home Repair Tutor explains in this video why Flush ‘n Sparkle™ is the best option for you when it comes to keeping your toilet bowl sparkling!

Chlorine gas is highly corrosive and can weaken the tensile strength of the fill valve and other tank components that sit above the water line. Off-gassing can lead to severe external leaks and potential property damage as well.

Frequently Asked Questions

  • Why doesn’t my sealant ring stick?
    The flush valve seat may not have been prepared properly. Make sure you have properly cleaned and thoroughly dried the flush valve seat before installing the sealant ring. It is very important that the sealant ring not come into contact with water prior to seating the sealant onto the drain or porcelain seat. If the sealant ring has been in use for a period of 5 years or longer and comes loose, replacement sealant rings are available to purchase. See Fluidmaster model 2602 on our website here.
  • How do I adjust my PerforMAX® flapper to save water and still achieve a powerful flush?
    The PerforMAX® flapper is a dial. By rotating the flapper within its rigid frame you can allow the flapper to close sooner or stay open longer. For more water savings, dial the flapper down to a lower setting. If the flush is weak, set the dial to a higher number.
  • Can I replace the flapper without replacing the entire Flush Valve Repair Kit?
    Yes, the PerforMAX® flapper is sold separately. It is Fluidmaster model 502, click here.
  • Is the PerforMAX® fill valve also sold separately?
    Yes, the PerforMAX® Fill Valve, model 400AH is sold separately. For information on where to buy click here.
  • Can the PerforMAX® Fill Valve be repaired?
    Yes, repair parts are available. For a list of repair parts and where to purchase them, click here.

Determining your toilet's noise and how to fix it

This article on toilet making noise defines simple solutions for:

1. GHOST FLUSHING: This can happen intermittently, cycling every few minutes or every few hours

2. FILL VALVE HISS: A noise that is constant and sounds like forced air moving through the toilet.

3. WATER RESONANCE: (constant thumping) A noise you hear when the toilet is flushed and the toilet is running water during its flush cycle

1. GHOST FLUSHING:
This refill sound is alerting you that your toilet is losing water, either internally (if there’s no water on the floor or exterior of toilet) or externally leaking if you see water outside the toilet.

Internal Water Loss:

  1. Check refill tube first: If refill tube is inserted or shoved into the overflow pipe, remove it and reattach clipping the tube to the overflow pipe. This will keep the tube from entering the overflow pipe and stop the leak.
  2. Clean bottom of the tank and flapper area and replace flapper. To determine which size flapper you need, please click here: Determine size of toilet flapper.
    If you need a 2″ flapper, we recommend the 502 flapper; if you need a 3 ” flapper, we recommend either the 513A flapper or the 5403 flapper
  3. Replace flush valve drain (last resort if 1  and 2 do not resolve the issue).

External Water Loss:

  1. Water draining from bottom of tank around fill valve and water supply connection: Leaks coming from the bottom of the fill valve that have been in use for a long period of time (not new installations) should be removed along with the supply line and replaced.
  2. Water draining from the bottom of the tank from the fill valve and water supply connection: Remove fill valve and clean bottom of tank both inside and outside. Make sure the shank washer is placed on fill valve first (it is designed to seal tank from the inside of tank) and install valve. Hand tighten the fill valve lock nut. If using water supply line older than 5 years replace supply line.
  3. Leaks coming from under the tank onto the toilet bowl: These leaks indicate failed bolt seals. The tank to bowl gasket and toilet bolts with washers should be replaced.

Watch this video to fix ghost flushing of your toilet:

2. FILL VALVE HISS:
This noise is alerting you that water is constantly passing through the fill valve and going into the tank.
Read more below or or watch this video:

Here are some steps for removing the top cap and flushing out debris from the fill valve:

  1. Turn off water supply and flush the tank.
  2. Reach inside the tank with your right hand under the float cup and lift it up. With your right hand hold onto the gray shaft keeping the float cup all the way up. Do not allow the float cup to drop or valve shaft to turn.
  3. Place your left hand on the top of the valve cap and while placing your left hand thumb on the side of the arm coming out of the top. Turn the cap and arm counter clockwise 1/8th of a turn to unlock. You should be able to lift off the cap and lever from the valve body.
  4. Once the cap assembly has been removed inspect for debris on the seal (rubber disc with pin coming through) and also the valve portion still in the tank.
  5. Hold a cup upside down over the exposed opening of the valve and turn on the water supply full force for 10-15 seconds, allowing the pressure to free any debris inside the valve inlet.
  6. Reassemble the top of the valve by placing the cap arm next to the refill tube. To lock, press the cap down while turning it and the arm clockwise.

  7. The bottom hand is lifting up on the float cup which raises the black arm under the top cap. The top hand is gripping the cap while the thumb is pressing on the raised lever arm.

Watch this video on how to remove and replace cap assembly of the fill valve:

3. WATER RESONANCE:
This noise is alerting you that your shut off valve at the wall has an obstruction in the flow path of the water. Here are some solutions:

a). If you are based in the U.S., we recommend using a regulated fill valve to stop noise like our 400AH PerforMAX® Fill Valve or the 400H PerforMAX® Toilet Fill Valve

If you are based in Canada, we recommend using the 400H PerforMAX Toilet Fill Valve

PerforMAX® fill valves come with a regulator built into the valve to slow down the incoming water. By reducing the speed by the incoming water we can stop the resonance noise that is       occurring.

b). If a PerforMAX® Fill Valve does not stop the problem then the buildup of debris in your shut off valve is so severe we recommend replacing the shut off valve at the wall.

c). If you need to replace any of the toilet parts, why not get Fluidmaster’s Everything Kit includes everything you need to fix your toilet in one purchase?

If you are in the U.S. and have a 2″ flush valve toilet, we recommend the 2″ Everything Kit

If you are in the U.S. and have a 3″ flush valve toilet, we recommend the 3″ Everything Kit

If you are in Canada and have a 2″ flush valve toilet, we recommend the 2″ Everything Kit

If you are in Canada and have a 3″ flush valve toilet, we recommend both the 540AKR Flush Valve and the 400H Fill Valve

How to easily maintain a Fluidmaster fill valve

Fluidmaster fill valves are made to deliver years of flawless flushes. Here are some simple steps you can perform to maintain your Fluidmaster fill valve which will keep it in tip top working condition.  All of the parts and product we recommend for replacement in this sheet are available at local home improvement centers. 

Read below for information on:

1. Inspecting your fill valve

2. Cleaning your fill valve

3. Replacing your fill valve and other parts on your toilet

1. Inspecting your toilet fill valve

  1. Look for any discoloration in the fill valve (looking for a bleached or faded type of discoloration).  This indicates age and wear that could compromise the function of the fill valve. In this case REPLACE THE FILL VALVE. We recommend the 400H PerforMAX toilet fill valve, the most powerful fill valve.
  2. Look to see if rust is above the water line and/or rust or discoloration on the top cap lever arm assembly that is attached to the adjustment rod. If there is evidence of rust or it is discolored Fluidmaster recommends replacing the fill valve. If you have a stainless steel adjustment rod the valve is out of warranty period and should be replaced.
  3. Look for signs of leaking at the water supply line to the fill valve (outside tank). Inspect the water supply connector. Replace it if it is worn or over 5 years old to prevent flooding and property damage.

2. Cleaning your fill valve

  1. If the outside of the fill valve has calcium and mineral build-up; clean the valve by using vinegar and an old tooth brush to dissolve and break off the build-up on the surfaces of the fill valve.  Then wash valve with warm soapy water and then rinse with fresh water.
  2. Once a year, or if the fill valve will not turn off, remove the cap assembly and inspect for debris in the valve body seat. Use an inverted coffee cup over the uncapped valve body and turn the water on all the way for three or four seconds then turn off.  Do this twice to rinse out the valve.  Remove and clean the seal and the cap assembly then reinstall.

See video below on flushing (cleaning) your fill valve

3. Replacing your fill valve and other parts on your toilet

  1. Replace the Top Cap Assembly (model 385) with master seal every 5 years
  2. Replace the Refill Tube with Refill Clip every 5 years (model 215)
  3. Replace the water supply line when you replace the entire fill valve. Fluidmaster Click Seal® Toilet Water Supply Connector is recommended: A perfect seal every time without over tightening.

See video below on how to remove and replace cap assembly of the 400A fill valve

How "Adjustable" toilet flappers work

This article will address both how adjustable flappers work and instructions for adjusting an adjustable flapper.

How Adjustable Flappers Work

  1. Traditional flappers use air to hold the flappers open, adjustable flappers don’t allow the flapper to trap or hold air inside their cone/bulb.
  2. Adjustable flappers are designed to flush toilets that use a flush volume of 1.28 and 1.6 gallon per flush (GPF)
  3. Adjustable flappers should not be used on toilets made before 1994.
  4. Adjustable flappers may use a float to delay the flapper from closing right away.
  5. Adjustable flappers may use a dial in place of a float. The dial sets a secondary hole in the flapper cone to release air and force the flapper to close.

If you are unsure, which size of flapper you need for your toilet, please click here: Determine size of flapper

Instructions for Adjusting an Adjustable Flapper

Fluidmaster flappers can be adjusted in three different ways:

  1. Turning the flapper cone from a minimum to maximum setting, so you are moving the secondary hole away from the top of the tank which traps the air in the flapper cone for a longer period of time.
  2. Moving a float (a float is placed on the flapper chain) up the chain, so you are setting the flapper to close faster. By lowering the float on the chain you are causing the flapper to stay open longer.
  3. Pulling slightly on the cone and turning the cone from a minimum to maximum setting, so you are closing the cone window and causing the flapper to stay open longer.

If you need a 2″ adjustable flapper, we recommend the 502 toilet flapper

If you need a 3″ adjustable flapper, we recommend the 5403 toilet flapper

How to fix water hammer or resonance causing loud noise

Read below for information on how to fix:

1. WATER HAMMER: A loud bang in your pipes after a fill valve shuts off. Water hammer can be caused by worn or damaged faucet washers as well as heavy build up of minerals and rust inside shut off valves (located on the walls of your home).

2. RESONANCE: The rapid banging or “Jack Hammering” sound in a pipe during the fill process, during the flush.

1. WATER HAMMER:
Follow these steps to try and resolve water hammer:

  1. Shut off water supply to the house at the main.
  2. Open all the cold water faucets, start with the highest faucet (2nd or 3rd floor) and work to your lowest faucet (first or basement floor).
  3. Flush all the toilets in the home.
  4. Let water drain from open faucets. Wait approximately 20 to 30 minutes.
  5. Turn on water supply to the house at the main.
  6. Wait 5 to 10 minutes to let faucets regain a strong stream and flow water.
  7. Close all the cold-water faucets starting with the lowest faucet (first or basement floor) and to the highest faucet (2nd or 3rd floor).
  8. Toilets will automatically refill.
  9. Once all faucets are closed and toilets filled, flush toilets to check for water hammer.

If this does not resolve your issue, try these tips:

  1. Reduce flow from shut off valves (wall or floor valves).
  2. If you are not using a regulated fill valve (a toilet valve that regulates flow into the toilet tank), try replacing the toilet fill valve with a Fluidmaster PerforMAX® Fill Valve.
  3. If reduction of shut off valve does not resolve issue, Fluidmaster recommends calling a plumbing professional to help resolve the issue.

If you need to replace any of the toilet parts, why not get Fluidmaster’s Everything Kit includes everything you need to fix your toilet in one purchase?

If you are in the U.S. and have a 2″ flush valve toilet, we recommend the 2″ Everything Kit

If you are in the U.S. and have a 3″ flush valve toilet, we recommend the 3″ Everything Kit

If you are in Canada and have a 2″ flush valve toilet, we recommend the 2″ Everything Kit

If you are in Canada and have a 3″ flush valve toilet, we recommend both the 540AKR Flush Valve and the 400H Fill Valve

2. WATER RESONANCE:

Follow these steps to try and resolve resonant noise (resonance) or watch this video:

    1. Turn off water supply and flush the tank.
    2. Reach inside the tank with your right hand under the float cup and lift it up. With your right hand hold onto the gray shaft keeping the float cup all the way up. Do not allow the float cup to drop or valve shaft to turn.
