While replacing a fill valve for a two piece American Standard toilet
my assistant managed to put pressure on the overflow tube instead.
Hearing a distinct "crack" sound alerted me to expect another problem.
Expectation confirmed when the tank slowly kept draining causing the
fill cycle to repeat.
I'm guessing that repair will require shutting off the supply,
disconnecting supply line, removing tank, and finally removing any
locking rings to remove the tube assembly. I'm expecting a
straight-forward operation. Any surprises to watch out for. Any
suggestions regarding steps commonly overlooked?
The current tube assembly was plastic. Should I stay with that or is
there any advantage to using metal?
