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?
Thanks.
