Like any pump, the Matala GeyserFlow pump will wear down over time and require replacement parts in order to work properly again. If your pump is not working, trips a breaker, doesn't start or makes a grinding sound, it might be time to replace worn parts.
How to Know which Parts to Replace
If your direct drive pump trips your outdoor GFCI but does not make noise and runs fine when plugged into a non-GFCI outlet, you probably need a rebuild kit. Your pump probably just needs fresh oil, gaskets, and o-rings.
If your direct drive pump whirs or hesitates, but will start when you manually spin the impeller, your pump probably needs a capacitor.
If your direct drive pump makes a grinding sound, it probably needs new bearings.
If the shaft on your direct drive pump is stuck and doesn't move at all, you probably need a new pump.
