I'd like to replace the fresh water pressure pump on my 3270 with one that still has spare parts available. We've been running the "backup pump" for awhile with the intention of getting a new one, and of course the diaphram on the "backup pump" went south over the weekend. I like the looks of the Jabsco parmax 3. We have an accumulator, but I'm not sure whether to opt for the high pressure or low pressure version of the parmax 3. Any suggestions on the pressure or pump type?

In the interest of documentation, I decided to repond with what I learned.

The accumulator pressure dictates the pump cut in. In my case the accumulator is charged at 20 psi. The par 4 model I picked cut in at 20psi and charges to 40 psi. I had a flojet 3.2 gph pump on there as a backup that the accumulator ate alive. Had I researched the pump (it was laying in a box in the cave when I bought the boat), I would have noted that it was not supposed to be connected to an accumulator equipped system.
