Motor Operational however overload protection trips If pump stops dismantle pump and check condition of partsĬheck Coupling and Damaged Shaft. Check water level and determine if low level alarm should be fitted.Īs symptoms are similar to that of a pipe leak it is prudent to reduce the pressure switch setting. Low water level is causing pump to recirculate water. Check amps drawn, if more than 3-6 times starting current pump will need dismantling, cleaning, repair and rebuilding.Ī check valve which is worn or is kept open by particles will not withhold pressure within the pump. Check for water ingressĬheck for sand ingress in base of pump or damage. Have motor resistance checked, and voltage. Check phase continuity and cable for water ingressĬheck voltage on switch and contact pointsĬheck condition, voltage and resistance within unit. If in open body ensure cooling sleeve is being used. If pump is solar powered, check age of panels as their efficiency decreases 1% per year, and more panels may need adding to maintain required power supplyĬheck fuse, check water level in borehole to establish if pump is running dry. If nothing has changed recently then it would be prudent to work through our troubleshooting guide below to try and determine the reason for failure.Ĭheck voltage at each terminal is within +- 10%. The first check when any pump stops working is to understand if anything has changed recently possibly contributing to the pump stoppage. It is not until the pump stops delivering water that fault finding begins.

A Borehole pump is often thought to be working fine as it operates out of sight, submerged deep underwater, or within a well.
