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:
