I am about to replace the water control SmartValve in an American Standard
Champion toilet. (The waterflow does not shut off at end of filling up the
tank.) American Standard was good enought to send me a replacement part
(Fluidmaster, adjustable) under warranty coverage, but no instructions
Since I have never done this before, I would like to know if any type of
sealant is required ? and, if so, what should be used and where should it
The replacement Fluidmaster is now installed. A slow drip/leak is one
problem. I do not yet know if the leak is from water within the tank or
from the coupling at the water feedline outside the tank. A rigid section
of tubing is used between the wall shutoff valve and the tank. I might
need to tighten that coupling some more.
The other problem is that, it seems to me, the water level within the
bowl is not what it was when the original SmartValve was in use. I think
the water valve is closing too soon. I also notice that the water does
not flow through the flexible tube into the overflow stack. Adjustment
of the Fluidmaster "Water Level Adjustment" plastic screw does not help
to raise the water level within the tank to the level that it was when
the original SmartValve was installed.
Thanks for the info. The .pdf instrux helps a great deal. It turns out
that I did not do the float height adjustment. I will have to take it
apart and do that now. Too bad that AmericanStandard did not include any
Looking at the original SmartValve, I am unable to turn the height
adjustment. Is there a locking mechanism that must be undone ?
Should there be waterflow through the flexible tube into the ?Overflow?
stack at the end of the fill cycle ? I think that that would flow into
the bowl until the Fluidmaster valve closes off.
There is no locking mechanism. You need to turn it harder. Make sure you
hold the bottom of the tube firmly when you turn the top.
Yes, the flexible tube should go into the overflow tube. There is a clip
that should hold it in place.
