might save a changeout
why are you changing out?......got a leak? just like porcelin bowl ?
if you have a leak, the new water valves that are activated when you stand on flush pedal....are a must to get....originals were crap [no pun !!]....new redesigned ones that fit 300/310/320 dometics are a snap to replace...bought mine on ebay $27 i9ncluding shipping.
