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.
2Can a blocked suction intake cause this issue?
Definitely. A clogged suction intake restricts water flow. Clean the suction intake thoroughly to restore proper function.
The tank has run dry
1Should the tank ever run dry?
No, the rain back up in a box should pump a minimal amount of water into the underground tank. If it is not doing this then the float switch may be stuck which is not triggering the box to top up or the solenoid valve may be faulty.
2Is it possible that I have used all the water in the underground tank quicker than it can top up?
Yes. The mains water top up is significantly slower than the pumped usage especially is using a hose pipe for prolonged periods. Try to reduce the length of time you are using the hose or raise the level of the float switch to ensure you have sufficient water in the tank.
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.
