A guide to common submersible pump problems and how you can overcome them.
Does your pump not start?
- Check the power supply
- Check that the fuses haven’t blown and need replacing
- Is the cable damaged? If so either remove the damaged section or replace it
- Check that the stator windings haven’t burnt out
- Examine the impeller to make sure it's not blocked or jammed. If it is then simply clean the wet end out
Pump starts but then stops pumping?
- The impeller might be blocked or the strainer clogged; both can be overcome by cleaning of the parts
- Check the discharge the pipe to ensure sure that isn’t blocked
- The voltage may be either too low or too high in which case contact your power company
- If the pump is running dry or the water is too warm (above 60 degrees C), turn off the power
- Is the pump still suitable for the application? Feel free to contact us if you are unsure
Is the pump giving too little output?
- The impeller rotation may be wrong
- Check the wear parts and replace them if worn out
- Examine the discharge pipework and replace if leaking or cracked
- Another reason why the pump may be giving too little output is if the discharge head is too high; where this is the case, you may need to use a larger pump
- Check that the pump is submerged in enough water
