My MJ pump has slowed down or stopped.

Friction heat can cause calcium particles to build up on the impeller shaft.

Every 3 to 4 months, or whenever performance is reduced, soak the impeller in white vinegar for an hour, then gently work the moving parts back and forth under flowing tap water to rinse and remove these deposits.
