My Cal 27 has an old hot water heater that works on 120v only now. It had a heat-exchanger for engine coolant but the diesel died in 2006 and I have removed all the old hose and crap the PO left behind.
The boat sits on a mooring behind my house for 6 months of the year during the sailing season. The other half-year is at the marina where I have shore power.
I have a plumbing problem where the fresh water pump never stops running. I've checked all the lines, etc. and am ready to bypass the hot water tank to see if the pump with the expansion tank stops running when this "tank" is out of the loop, so to speak.
Given the above, my question is should I set up the plumbing with ball-valves to enable me to use the tank when I might have access to AC but remove it from the plumbing circuit during the summer period. The tank is 6 gals or less I believe based on the size of the tank.
Leaving water in the tank for 6 months seems like a bad idea, so draining it seems logical. Is it though?
The hot water tank is inside some type of SS "box" where the 120V cable enters and there are the former engine heat exchanger ports and the current water system connections. There is a pressure relief valve near the top, but no draining port. I'm tempted to pull it out and investigate it on the garage work bench.
Costco 16 oz water bottles keep me sailing but that not what the world needs long-term.
Thoughts ?
