I need a plumbing diagram for water storage tanks.

We have a well (on a manual timer) pumping up to a single storage tank. The well feeds the tank through a 2" line. The tanks then gravity feed the house back through the same 2" line.

We are going to replace the single tank with two 2500 gal. tanks that are inter-connected. They are poly tanks and they each have a 2" plumbed outlet in the bottom and a 1 1/2" inlet in the top.

We want to inter-connect the two tanks so they are self equalizing. I want to make sure I get the check valves and best perormance.

Any advice or links would be appreciated.
