Trying to pump out groundwater after heavy rain.
Have moved pump out of excavation above pool and attached quite a long suction side hose but now having probs.
Is there a limit as to the length of suction side hose and height of pump?. when hose was short and pump down in excavation, pump was working but I need to have the pump out of the pool area. Is this just a matter of insufficient priming water in the suction hose or too long a hose/too high a pump?
