Review on 🚽 Fluidmaster 400CAR3P5 PerforMAX Toilet Fill Valve and Flapper Repair Kit – Adjustable and High Performance for 3-Inch Flush Valve Toilets by Black Miller

Decent quality and easy enough to install the whole thing, but once installed I found that you can simply replace the top half of the section meaning you don't even have to unscrew the nut from the bottom. The bottom tube stays attached to the bottom of the tank and the old top slides up and down while the new top slides down the bottom tube. This is possible because usually only the membrane is defective, and then in the upper part. If water continues to flow into the tank, the diaphragm is most likely defective. Replacing the top only takes about 2 minutes and requires no tools. Do an internet search to find out how to replace the top. This will only save you time and make the repair much easier. I wish you all the best of luck.
