Frequently Asked Questions

  • What is the difference between the 400A and the 400H toilet fill valves?

    • The 400A is a standard refill valve that controls the water in the tank, it controls fill time and water level. The 400H is a performance fill valve that also controls the water in the tank. The 400H fill valve has an additional adjustment for the water in the toilet bowl using an independent adjustment knob. The 400H can be adjusted to let more or less water into the toilet bowl without affecting the level of water in the tank.

  • What is the Fluidmaster toilet fill valve that I should I purchase to replace my original 400 fill valve?

    • Fluidmaster make three fill valves that can be used to replace 400 valves that originally came in your toilet. Choose from the 400A, 400H and 400LSR fill valves.

       

  • How do I choose the right Fluidmaster fill valve for my toilet?

    • Fluidmaster suggests using the 400A when replacing antiquated technology such as ballcocks and or when replacing “like” valves. Toilets manufactured after 2005, or are marketed as “Dual Flush, High Performance, or HET (High Efficiency Toilet)” we advise using the PerforMAX® 400H High Performance Fill Valve.

       

  • What does higher refill rates mean when describing a fill valve?

    • The Fluidmaster fill valve when activated fills both the tank and the bowl with water. The term higher refill rates describes the amount of water that is diverted to the toilet bowl. Our standard fill valve, the 400A, has a refill rate to the bowl that is standard for most toilets. A valve with higher refill rates can double the amount of water to the bowl and should be used on toilets that use less than 1.6 gpf or are stated to be higher performing toilets or High Efficiency Toilets.

       

  • What does H.E.T. mean?

    • H.E.T. is an acronym that spells out High Efficiency Toilet. What this term means is that the water consumption or usage of this toilet is less than the current government standard. The current standard for water usage in a toilet is 1.6 gallons per flush (GPF). Toilets that use less than 1.6 gpf are higher performing toilets or High Efficiency Toilets.
