A life saver.;

The Fluidmaster solved my running toilet instantly. This items is truly universal. I had a toilet that no matter what I did to adjust the fill valve, it wouldn't stop the water from running over into the pipe. I figured I needed a new fill valve. If you have an American Standard VorMax and wondering if this fill valve will work, it will 100% work. As a matter of fact, it works better than the one that originally came with the tank. I plan to purchase more just to have around the house. My handyman put in the tank quickly and I made a few adjustments to the valve concerning how much water I wanted in the tank and bowl, and boom, DONE! I highly recommend this product!

Easy DIY, even for a beginner. Simple adjustments

This toilet fill valve was easy to install for most any DIY'er. The water level adjustments (tank and bowl) and inside tank height adjustment are a definite plus and so easy. Local home improvement store charges $150 to install per their website, so save yourself some money.

Great product for any fill valve replacement

This is an excellent product for anybody that knows about the working parts of a toilet tank. Probably don't really need the adjustable flow tube for bowl level for most toilets, but it's a cheap extra for "just in case" and maybe helps keep the bowl cleaner. I will last many years, and when the shut-off gasget/washer eventually begins to fail, it is easily replaced. Pay attention to your tank height and adjust the tube controlling float height before installing it in the tank.
