Pump Does Not Run
1Why won’t my pump turn on?
One possible reason is that there is no electric power. Make sure the pump is plugged in and check the electrical supply to ensure it's working properly.
2What should I do if my pump is receiving power but still doesn’t run?
The pump impeller may be jammed. In this case, a professional pump overhaul or service and cleaning is recommended to resolve the issue.
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.
2What if the pump impeller has no water?
The pump impeller must be filled with water to function properly. Fill the system with water to prime the pump.
3Could 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.
4Can a blocked suction basket cause this issue?
: Definitely. A clogged suction basket restricts water flow. Clean the suction basket thoroughly to restore proper function.
5What if the suction height or pipe length is too much?
If the maximum suction height or pipe length has been exceeded, the pump may not draw water. Try adjusting the pump’s position closer to the water source or consider using a submersible pump.
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
1Could the suction height be too high?
Yes. Excessive suction height reduces the pump’s efficiency. Check the suction height and, if needed, reposition the pump closer to the water source or consider using a submersible pump.
2Is a blocked suction basket affecting the discharge rate?
Definitely. A clogged suction basket restricts water flow. Clean the suction basket to restore normal operation.
3Can 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.
4What 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.
Thermal Circuit Breaker Shuts Down the Pump
1Why does the thermal circuit breaker keep shutting down my pump?
This typically happens due to overloading caused by dirt or debris in the motor housing. The pump likely needs a professional overhaul or service and tank cleaning. It's important to have a technician inspect and clean the motor housing.
2How can I prevent this from happening again?
Prevent dirt and foreign objects from entering the system by using proper filters, keeping the water source clean, and maintaining a regular cleaning schedule.
