Had been using my shut off valve for a while now. Just never seem to have enough time to replace the inner workings. Got tired of having to always reach down and tweak the valve so I finally chose to do something about it.
Only took about 10 minutes and now I have better flushing power, faster and quieter fill too. Even if you have zero plumbing skills anyone can do this! The included instructions are well done and this will fit about 95% of all toilets that are out there. Wish I'd done it a lot sooner but now it's done and I probably won't have to worry about it again for another 15-20 years. The flapper valve is much better designed (rubber) than my original plastic valve (yeah it was THAT old) and will definitely last MUCH LONGER! So for less than $20 and maybe 15-20 mins of your time you too can feel as though you have a new toilet. The only tool you'll need is a crescent wrench or a pair of channel lock pliers, that's it. Oh and a cup to bail out the tank. Other than that all you have to do is shut off the feed valve and remember to turn it back on when your finished.
This is much better quality than the OEM original too in every aspect and function.

5.0 out of 5 stars Easy to install and been working great

Works great and wasn't hard at all to install.

Had an issue with my toilet. It was very slow at filling up one day and noticed the little water that did come out, was from the top of the water pump and not the water hose. Simple research found it was the pump. Instructions online and in the manual were easy to follow and it really only took 45 mins to take out the old one and install the new one. Honest its likely less time then that as i had to do alot of cleaning associated with changing out the pump.

Its not rocket science and beats paying a plumber $200 when it really should be $15 plus 30 mins of your time.

5.0 out of 5 stars Had a noisy toilet refill...

This is about the easiest plumbing fix there is. I had a loud refill noise on one of the toilets. Read that this is usually the fix. I installed it in 20 mins, the new fill valve worked great, and the noisy refill problem was resolved. Happy wife too. Plus, it has a better water flow adjustment than the old one. I should be able to save on water too.

3.0 out of 5 stars Easy to install but takes time

My old toilet had old Fluid master fill valve which stopped working after a year. Looks pretty much the same as the old model but hope that it will last longer.
