Hello,
As a relatively new trawler owner ('91 GB 36), I'm not sure what my fresh water pump cycle should be. I had some concern that it was cycling too frequently. There is a Jabsco 30573 accumulator, and I suspected it needed more air pressure.
I have not addressed that, but I did install a new pressure relief valve on the hot water heater, as the old one had developed a leak. And now, the pump sequence is much less frequent when I use hot water. But when using cold water, the pump frequency is the same as before - more rapid. I can move the lever on the galley sink from all hot to all cold, and there is a range, from less frequent to more frequent.
I can check the accumulator air pressure and pump it up if necessary, but I want to understand what the underlying issue may be with the variance in the pump sequence between hot and cold. It makes no sense to me why replacing the hot water tank relief valve would make this happen, and why it would happen at all.
Thank you for any advice!
Mike
