Well Pump Troubleshooting and DIY Repair
The pump controller houses a capacitor to help start the pump. Most pump controls are mounted in the house near the pressure tank, but others are mounted inside the well pump itself and the fix requires a pro. If you don''t have the box shown below, this fix isn''t for you. There''s no way to test the controller, so you either have to risk blowing $75 by replacing a …
