Customer Reviews

Had one on a newer toilet and…
Well, I have an old, (circa 1958), toilet in my full bath. I replaced the float with one that I happened to have on hand back a couple years ago. It was one with the ball float. Last month it started SLOWLY leaking into the tank. Just yesterday it gave up the ghost and started running pretty darned fast. I remembered that I had a new float assembly that I bought a couple months ago when it started leaking in the first place. I was meaning to get to it when I could. Funny, that happened to be today. I have never really thought about the brand or the style of the float before.
When I took the old ball float off I unscrewed the top of it to see how the thing worked. I had found that the chlorine wore away the little o-ring that keeps the water from flowing when the float is raised. I thought, “This is a crappy design. Using a rubber o-ring with all the chlorine just sucks.”
I pulled out the one I bought at the store a few months ago and thought that it looked better than the old design.
I put it on along with a new chlorine-resistant flapper. I then remembered that in 7 years I have never had any trouble with the float in my low-flow replacement toilet in my half-bath. I went in the half-bath and removed the toilet tank cover to see what it had for a float. It turns out it has a Fluidmaster 400a as well! Holy crap! This is awesome! I stumbled upon the same type of float that has not failed me in 7 years!
I highly recommend this float.
Easy to install.
Easy to adjust.
Seems to last a good long time too.
