[C320-list] water system leak?

[Pat Moriarty]

Ok I sent this in once already. Your leak is inside the pump and nothing 
will fix it but cleaning or replacing the pump. The more water system in 
service the more expansion and increased your cycle time. It will cost you 
nothing but time to take the pump apart and rinse the valves etc then 
reassemble. Something like a hair or calcium build up will cause a cycling 
problem. The intake side can not be a problem or you would have a leak 
without the pump in service or you would have cavitation because you are 
sucking in air and the pump would not turn off as air will not pump up to 
pressure.
