Just purchased the vessel.
Filled fresh water tank (S) took a good 1/2 hr to fill.
Pump and systems worked short term, until following morning.
Following morning no water being pumped through system although pump was running, taps etc spitting under pressure.
Boat had been laid up and winterized , this was the first time using on board system.
Are there drain valves for emptying water tanks for winterizing that may need to closed.
I did see water in the forward bilge so I am assuming fresh water tank (S) drained empty.
Sure hoping the tank (s) aren't busted!
Carver manual didn't shed much light on this topic.
All systems work when on shore water at marina.
Reaching out to community for advice.
