How many GPM is enough for a fresh water pump?

[HB of CJ]

We have found that thru personal experience it is more important what the water pressure of the pump is rather than the absolute volume of water it puts out.

Reasoning here is that you will always eventually run out of water and usually at the most in-convenient time.   Higher pressure gives the illusion of using less water.

A hot shower at 50 psi and 2.5 gpm "feels" more refreshing than 6 gpm at 30 psi.  It least it does for us.  Go with the higher pressure pump if you have that choice.

I have two Shurflo whisper king water pumps that are in parallel so that I can turn both on at the same time for those times when one is in the shower and the other is washing dishes-can't feel the difference in pressure when both pumps are on.  Plus the redundancy of having two pumps.  Good Luck, TomC
