Re: Priming you water pressure pump
I have the same problem in the spring. I find that i get some air bubbles in the system some how and it takes a while to get them out.
Don't ask me how; i don't know why. I have pressure and it will keep for a week(or more, never checked how long it would hold).
I have 2 tanks with separate shut-offs next to the pump. I turn off the shut offs which causes a vacuum at the pump; which in turn starts drawing the water and pumping again. Once i do this a couple of times while i'm flushing my tanks out it seems to remedy the problem. I also switch the valves back in forth as well.
It took me a while to figure this out. I'm not sure it would work on every boat though.
Maybe not the best explanation.
