It cannot replace an older model of Fluidmaster Duo flush valve.
I bought it for replacing an older model of fluidmaster Duo flush valve due to leaking. But it is actually only for replacing an traditional one flush valve. So I had to buy a traditional flush valve and then install this one. Also the installation manual is not very clear.Verified purchase: YesCondition: New

Still in the box
Fiddled around with this thing for a couple of hours - Even after talking with the OEM I could never get it adjusted right - my wife suggested to keep using the existing flashing mechanism.Verified purchase: YesCondition: Pre-owned

Easy install once I got the proper handle.
It definitely will save water. To avoid any future problem, I bought a horizontal flush valve. The original package had the wrong handle but a call to Fluidmaster solved the problem. I should have known by the description that it was an open box and could be a problem.Verified purchase: YesCondition: Pre-owned

Cheap
When I first install this product it seems to be working fine, a few days later it began to run continually, so I took it out to inspect it and replace it. Now I have to hold the handle (up or down) just to get a fliud.Verified purchase: YesCondition: New
