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 included.
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 be applied?
TnX.
