The Pump is not running
1Why isn’t my system turning on?
A common cause is a lack of electrical power. Confirm that the system is properly connected to a power source and check that the outlet or circuit is functioning correctly.
2What if the system has power but still won’t start?
There could be an internal blockage or mechanical issue, such as a jammed component. It’s best to have the system inspected and serviced by a qualified technician for cleaning or a complete overhaul.
Pump Does Not Draw Water
1Could the suction valve be the problem?
Yes, if the suction valve is not submerged, the pump won’t draw water. Make sure the suction valve is positioned below the water’s surface.
2Could there be air in the suction pipe?
Yes, air in the suction pipe can prevent the pump from drawing. Bleed the air from the system and check for leaks that may be introducing air.
3Can a blocked suction intake cause this issue?
Definitely. A clogged suction intake restricts water flow. Clean the suction intake thoroughly to restore proper function.
Pump Does Not Switch Off
1Could an open outlet be causing the pump to stay on?
Yes. If an outlet (such as a tap, or toilet filling valve) is left/stuck open and water continues to run, the pump won’t switch off. Make sure all outlets are closed.
2What if there’s a leak in the system?
A leaking pressure hose or outlet can prevent the pump from building enough pressure to shut off. Inspect for leaks and repair any damaged hoses or fittings.
Pump Discharge Rate Is Insufficient / lower than expected
1Is a blocked suction intake affecting the discharge rate?
Definitely. A clogged suction intake restricts water flow. Clean the suction intake to restore normal operation.
2Can dirt or debris in the system cause low discharge?
Yes. Dirt in the system equipment can reduce flow. Clean all components and have the tank cleaned and pump serviced or overhauled by a professional if necessary.
3What if the pump head height is too high?
A high pump head height can exceed the pump’s capacity. Check the head height, and if it’s too great, adjust the pump position or use a more powerful pump.
