water tank check valve question
I recently installed a second fresh water tank and teed the two tanks together together with a common suction line to the pump. I discovered that for some reason the new rear tank drains into the original front tank and flows out the front tank fill port and on to the ground. The new rear tank does have its own fill and vent port. I want to put a SharkBite Pex check valve in each tank outlet line to eliminate this problem. The Sharkbite check valve needs at least 2psi to function. Does anybody know if the water tank pressure combined with the pump suction will overcome the check valve resistance? Thanks.
