let me start with a description of the pool.1 main pool 4ft. to 8ft. deep and pool 2 is 1ft. to 3ft. deep. the water level of pool 1 is 18 inches higher than pool 2 and that pool 1 overflows to pool 2 on the side they are connected. we have the hayward DE7020 filter with a vari-flo control valve SP-715XR50.do i need to put check valves for the drain system right before the pump suction or after the vari-flo valve for the return system or both. do i really need to install check valves even if all pipes have ball-valves? where will be the proper position for them? thanks
