Rated 4.3 out of 5 by 22 reviewers.
Rated 1.0 out of 5.0 by Quality? Lasted 3-4 months. I've installed 30-50 Fluidmaster fill valves in my apartments over the last ten years. So when my own home's toilet keep running, I opened the contractor's pack I keep handy for apartment repairs and threw one in. 3 months later, the toilet is running again. I install the second fill valve, and disassembled the 1st fill valve to check for small rocks or? in the valve shut off. Come to find out, the stainless steel pin that pushes on the rubber diaphragm to shut the water off poked through the diaphragm and caused the fill valve not to shut off. See photo I don't know if it's just these contractor's pack or poor quality parts. I don't need to do repairs over and over, so I installed a different brand of fill valves. June 23, 2013

Rated 4.0 out of 5.0 by Fill Valve The Fill valve was easy to install. I installed with the tank off but it appears you could easily install with the tank on. May 10, 2015
