Clogs in your well pump can be fixed for $100 to $300, depending on where the clog is. Repairing broken inlet or outlet hoses are more expensive. Often times, repair cannot be possible if the damage is to the unit itself. If the unit is repairable, expect a cost of $200 to $500 to repair the pump to working form. Pipe breaks underground are another matter. If you are experiencing a loss of water pressure in the system, chances are there is a leak somewhere in the line.
