Itís sucking air from someplace, but thatís the riddle. Backstory - I replaced the heating
element and thermostat on the water heater
. From that point on, the pump
took longer to cycle on and then off. That is, I could use more water
before the pump
would kick in, and it took longer for the pump to pressurize the system. It was as though I had installed a bigger accumulator. I was wondering if the water heater
had started to function like an accumulator.
Coincidently, I discovered a leak in the aft water tank. The location of the leak is still unknown, but when I fill the tanks
, I find water in a compartment next to the aft tank; a compartment near the batteries
and the selector switches. Once the tank is down to ĺ full, the leaking stops. Yesterday I filled this tank, it seemed to take too long to fill; and sure enough, I found about five gallons in the main bilge
, but no water from the vent.
Recently, the water pump
has been cycling on, sucking air, when both tanks
still read ľ-Ĺ full; just as it normally did when a tank runs dry and you switch to the other. Sometimes, after a few minutes, it will pressurize, but usually I shut it off, fearing it will burn out from running dry.
I can deal with the leak by simply not filling the tank all the way, but the cycling pump is another matter. Where is the air coming from? Any suggestions on how to solve the pump problem without removing the tank?
