We have a Front Load washer, and I think it uses 2.5 gallons per cycle(Wash,
Rinse).
So we make it 15 GPM to be on the safe Side?

To add a Wrinkle The reason for having 3 Showers and Laundry going at the
same time is because I'm actually feeding 2 Houses. So there could be a
potential there that it could happen. Anyway...

So I'll have a Pressure sensor that is hooked up to my control Panel, and
the Control panel will Control the Pump.

Here is a Diagram of the Plumbing:

So how do I determine my GPM?
I figure 3 showers @ 2 GPM, and the Dish and Close washer at maybe 1 GPM,
so that would be 8GPM, so make it an Even 10 GPM, Pressure we would like
between 40 and 70 PSI . I think we are between 30 and 60 now and its a
bit low.


The flow sounds about right for showers, but the washer is probably more,
maybe 10 gallons itself. I don't know the capacity of the typical
machine, but I think they use 15 to 20 gallons per cycle so you can time
how long it takes to fill . "Normal" pressure is about 50 psi but 80 to
100 is not our of the question. If you have the right piping, that should
carry the load.

It is probably overkill to gear up to supply every water using appliance
in the house at the same time. If three people are taking showers, just
shut the clothes washer off for a few minutes and save a lot of
aggravation and potential temperature fluctuations.

What is going to turn the pump off and on? Is it going to be set up with
a pressure tank between the pump and point of use?
