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!

Be careful when adjusting the water flow into the 'tube' ...my brother had the flow too high which made it noisy AND it popped out of the tube and sprayed water everywhere from under the tank cover. Otherwise, i think I'm going to be pleased with it. 🤣😂😛👍🤷....i hope i described the problem so you'll understand what it did.

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.
