J-PRO-22 Spare Parts Kit

JPRO Service Video 

Most often, it is the injection check valve that first fails, due to the raw water quality.  Over time, especially in a room where the temprature goes up and down a lot, then these other parts are often needed to get the pump primed again.

We strongly discourage installing the JPRO pump outside, but for those that do, we recommending overhauling the pump any time the issue goes beyond the injector.
