Fluidmaster 400A133 Premium Filling Valve Universal High Performance Toilet Fill Valve - 3 Pack

These are so easy to install and they are completely adjustable to fill the tank as much as you need. One very nice feature is the ability to short flush by quickly flushing and releasing the handle just after and the toilet will flush with very little water. If you need more of a flush, hold it just a bit and use the whole tank for those "big jobs." I am hooked on these and hope they will always be available.

Very easy to install. 1 person job and no tools needed.

Very quick to install, I have installed several for people because of leaking toilets and haven’t had issues with the products. Easy and straightforward install, just shut water off take the old one out adjust for height and tighten the bit under tank and 15 mins or so and done

This units have plenty of adjustment a very nice flow. It fills the tank quickly at 50 psi household water supply pressure.

These flush valves were just what we needed to replace our leaking toilet flush valves. They are of good quality and the price is right. Thank you for making these available on Amazon for us.

I installed it, no problem! However, it was about 1 1/2 - 2” too long for my pool. I have to open up the pool filler opening and unscrew the Fluidmaster as far as it will go for it to work for me. (Better than the hose, I can’t tell you how many times I have over filled my pool)!!!

These are a good bargain with three to the box. Instructions were easy to follow and installation went well. With more and more "thin" plastic being used in production, its easy to break or crack while adjusting fill level rod.

Works great, but is annoyingly loud.
