400A Universal Toilet Fill Valve (Contractor 3-Pack) is rated 4.4 out of 5 by 88.

And louder than a Boeing 767 taking off if you turn the water valve all the way open. We have an 80psi line. When the tank is refilling, the water sounds like a jet screaming doing the runway. But, with a little adjustment to the valve and pressure, the sound level is reduced. At the same time, the amount of time to refill the tank is much longer.

Rated 4 out of 5 by from Good for the price This is a good product that'll get the job done. 3 fill valves come the pack for a pretty low price. Like I said before, its a good product, not the best. Reason being, is because I have to replace them at least once a year. Working for a non profit, we cant always buy the best of products. So the multi packs with decent prices always suffice for our purchases. I'd also like to point out, the type of water that always keeps these fill valves from functioning properly. I reside in San Antonio, Tx. The water supply here is "very hard". It has high levels of calcium and fluoride. This stuff scales up pretty bad over a short period of time and I believe the deposits enter into the fill valve and keep it from working properly or just not at all. Perhaps in an area with much less hard water, these fill valves would work well and last longer.

I have used this product before over the years, and have always been completely satisfied. I have had a plumber do a couple bigger jobs that I couldn't do, and he quoted me over $150 to replace the fill valve/flapper valve combo! For less than $10 and under 30 minutes of my time, I replaced the fill valve ( the flapper valve was perfectly okay). My wife watched, and said the next toilet that needs one replaced she wants to do it!

Rated 5 out of 5 by from Convenience for the Convenience The 3 pack made getting new flush valves so easy. Doing maintenance on a 3 bath town house makes it simple, go to Home Depot, pick up a 3 pack and go install! No hassle not having enough and having to go back to get more.

The toilets in our home are about 10 years old and that includes the inner components. We have already replaced the flapper and floater in the toilets, and it came time to replace the toilet fill valve. What I love about the Fluidmaster fill valve is that this newer design makes it so easy to adjust the water level. In the old units we had installed, it was very cumbersome to raise or lower the water level. With this product, there is a little slot where you can use a screw driver to adjust this setting. You approach it from the top and it couldn't be easier! Installation was very easy and all parts were included and easy to assemble (what little assembly was required). The instructions are easy to follow with pictures and detailed descriptions for each step. I love that this is a 3 pack, because you get the best bang for your buck! A huge advantage to this model, is that if you ever need to replace it, you don't need to remove the entire unit. You can keep the black bottom part in place that connects to the water line and pop off the top and attach the replacement.

I have had these before but in our case they only last about 1 year. Lot of sand and rust from the well here. Still think it should last longer. Very easy to replace, however.

Very easy to install, purchased the 3 pack because we have 3 toilets and I just wanted to do them all at the same time. This also eliminated the float and is easier to adjust.

Rated 4 out of 5 by from Fill valve This fill valve does the job. It was a little bit hard to understand how to adjust the height but once I figured it out it was a breeze.
