Pump repairs normally occur because of fine sand that has been pulled into the pump. Inside the pump build-up of this fine sand is basically unavoidable. However, the collection of this fine sand is not typically the cause of needed pump repairs. In fact, during normal pump operation the fine sand would pass right through your sprinkler system.
It’s not unusual during our rainy season for homeowners to turn off their sprinkler systems completely and for prolonged periods of time. Leaving your sprinkler systems off for extended periods gives this fine sand collected inside your pump a chance to harden.With the start of our dry season, most homeowners turn their sprinklers systems back on. A pump that has too much sand built up can’t properly pump water. Well pumps need water movement to keep it from overheating. A pump that has harden sand can run, overheat and basically burn out or stop running.
To replace the broken or burned out pump the entire length of pipe, pump motor & electrical wiring needs to be pulled out of the ground. The pump at the end of the pipe gets replaced and often it’s best to replace the old electrical wiring. The repaired system needs to be carefully lowered back in the original spot and casing to the correct depth of the water source.
