Water Flow with Expansion Tank
Water Flow using a 2 gallon pressure tank:
I hate it when the pump runs in the middle of the night when I am up using a small amount of water and then having the noise wake my wife and annoy the neighboring campers.
SO; I installed a 2 gallon Water Worker G5 expansion tank set a 30 psi into the RV plumbing. Now we turn OFF the pump when retiring and we have a 55 second flow of water without needing to run the pump throughout the night.
When using the pump, instead of 2 seconds of flow before the pump starts a 4 second cycle we now have 18-20 seconds of flow followed by a 35 second pump cycle.
