There may be a leak in the
pipe system (>1.2 lpm)
Close the discharge pipe isolation valve. If
the pump stops after approx. 20 sec then
the issue is a small water demand / leak
somewhere.
Check all pipework for leaks on both
suction and discharge side of pump.

Any small leak from a connection, tap or
leaking toilet etc. may cause a problem.
