Frequently Asked Questions

What is the difference between the 400CR and the 402CARHR, both kits have a fill valve and a flapper?
- Each kit comes with a different fill valve and flapper. The 400CR Kit is best used with toilets that use more water than 1.6 gallon per flush or toilets that predate 1994.

How will I know which size of flapper I need when buying a Kit?
- Fluidmaster manufactures a universal 2” flapper and a universal 3” flapper. To determine the size of flapper you need, measure the drain hole the flapper covers. If the hole is 2.5 inches use a 2 inch flapper if the drain hole is 3.5 inches use a 3 inch flapper.
