Question: Will the impeller fix my pump?

Answer: This depends on what signs your pump is displaying. Usually the pump will be rattling or vibrating with no flow or greatly reduced flow rate. You should unplug the pump and with dry hands open the pump cover by removing the screws on the front. Then pull out the impeller assembly. There should be some magnetic pull and if the impeller assembly comes out in multiple pieces or if a fan blade(s) are sheared or broken off or if the shaft is broken that should be a sign to change the impeller. Even if the there are no signs of damage, we recommend you do a pump test: Plug the pump in with the impeller assembly removed and place the impeller near the pump; it should shake which shows you that the pump is giving off magnetic pull. Promptly unplug the pump and an impeller assembly will probably fix your situation. If you don't get any magnetic shake from the pump than the pump is most likely defective and you should replace the entire pump as they cannot be repaired.


Question: Will removing the pump cover and/or impeller void the warranty?

Answer: No... Removing the pump cover and impeller is part of normal preventive maintenance and should be done every 6-12 months to keep your pump in perfect working order.
