Can any one suggest to resolve this problem?
1. frequent losing suction by pumps- partly due to common suction strainer choking in the sump, partly due to pump discharge check valve passing & air ingress from stand by pump.
2. pump discharge flow switch failure- the acting of flow switch cause stand by pump start
while facing this problem we are doing backwash from sump drain to clear strainer debris & increasing the sump level to 75% by forcing solenoid valves.
