Hello all -
Apologies ahead of time if I end up asking the the stupidest
questions you plumbers out there have ever heard, but I'm stuck. I'm
trying to replace a leaking flush valve in my American Standard
one-piece gravity flush (I assume) toliet. There's a constant leak
running into the bowl, and my water bill is starting to show it. It's
not the flapper, because I can hear the water running until I lift the
ballcock arm high enough for it to stop. When I do that, the water
stops running into the bowl as well. So here's my real problem. I've
replaced valve/ballcock on toilets in my previous house with the
Fluidmaster 10$ combos from Home Depot. This one's unlike anything
I've ever seen, and I want to be sure of what I'm doing. Instead of a
flush valve and refill tube being separate, this toliet has what looks
like the refill tube directly attached to the flush valve, screwed
into the flush valve at the top. There's a hose at the top of the
refill tube that runs into a side corner of the tank that I'm assuming
is the feed for the top of the bowl when you flush. Do I have to
replace this with American Standard replacement parts? I went to the
website, but that didn't get me anywhere (mostly sales stuff). Is is
safe (or even possible) to replace the AS setup with the regular
Fluidmaster and just run the feed tube into the side corner of the
tank? I'm assuming not. The toilet itself has 680 2007 stamped on the
inside of the tank. It also says 4192 - Apr 14 stamped into it as
well. Any help/insight greatly appreciated.
Flush valve is the part which has the flapper (or disc float)
and lets water into the bowl from the tank.
Ballcock is the part which lets supply water fill the tank
until the float arm rises.
You may be better off rebuilding the old ballcock. It should have
a replaceable rubber washer (the washer is similar to a faucet washer
but different size).
If a Fluid Master ballcock will fit the tank height, you can use it
and route the plastic refill tube into the cavity at the corner
of the tank. You *do* have to be certain the end of the tube
is kept *above* the rim of the cavity or self-siphoning can occur.
