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!

Since my swimming pool has an auto fil that uses a Fluidmaster fill valve and being outside they tend to fail after a season or two and also have two toilets that use the same valve , I stock up on them rather then go out and purchase one at a time. The contractor three pack is excellent for my needs and are cheaper the buying them separately

Rated 3 out of 5 by from 1/3 are bad I buy 3 at a time as my condo constantly turns water on and off for repairs. so the hydro pressure hammers these units hard. my experience has been that 20-33% of the time they fail right out of the box. Still when they work they work well. I have three toilets that get hammered by my condo staff and need to be replaced at least once a year.

Save a couple bucks each on the 3 pack, so now I have a spare. Not sure why I had to cut out part of the rubber seal, but it wasn't too big of a deal. Also, these are a lot louder than the original Kohler parts. Not a huge deal, but good to know up front.

The packaging indicates it's a feature that will alert you that the tank is filling. Not something you'd like to hear when you have to use the bathroom in the middle of the night.

Fluidmasters went in three different houses of the family, all worked just as expected. I have been using Fluidmaster since the early 70's, they have never let me down. Don't know why toilet manufacturers haven't used them a standard equipment, price has got to be close.

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.
