Rated 5.0 out of 5.0 by Best Bang for the Buck Toilet Valve Good instructions, just make sure to read them all. Easy install. Just make sure you clean any gunk or grit from any surface that needs to be water tight where a rubber gasket will lie. You might have to keep tightening the nut on the bottom until it stops leaking. The two I've done needed to be tighter than I expected. Don't forget to reuse any other gaskets from the water line. Also keep in mind you can pop off the top of these and clean/flush them if they're leaky. Sometimes grit gets stuck in the guts and causes a very small slow leak. July 2, 2014
Rated 5.0 out of 5.0 by Flushometer Easily install with limit tool and minimal skills. Great product for the money. February 11, 2015
Rated 4.0 out of 5.0 by Easy install, but very noisy The fill valve was real easy to adjust and install , but very noisy on filling the tank. I returned the 1st one and the second one was slightly quieter, but our little bathroom still sounds like an airport. Saying that, I would buy another one based on price, easy install and store location. I'm hoping our hard water will quiet it down over time. July 5, 2014
Rated 5.0 out of 5.0 by A four year old child could install this. Quick run out and find me a four year old child! Ok, I could not resist the Groucho Marx joke. This is an easy to install, simple, well manufactured product that is a universal fit. Money well spent. October 10, 2013
Rated 5.0 out of 5.0 by Universal fill valve...very good, compact design! Like many, I had the older fill valve with the float ball. The rocker part on top of the fill valve cracked, and was letting the water run. This new style, compact fill valve is very easy to install. There are lots of vids on YouTube if you are not sure about something, but really it's not hard to change the old unit for the new. The only pointer I would give is the make sure the line on the fill valve is 1" above the top of the water tube. If it's too low, you will here the water trying to refill the tank. It's all in the directions though! February 6, 2015
