a la Deja Vu. If you hook a garden hose to the front and back faucets of your house, turn them on, how is that gonna affect pressure at any of you interior faucets?
This would be a looped system so if you open a faucet anywhere in the house you could actually be fed from both sides of your water system. We did this in the desert in a Housing Development. It helps to maintain pressure throughout the system.
