Pressure & Pump Problems

Pressure issues usually indicate a system setup or control imbalance rather than a pump failure.

Pump Motor Insulation Failure (Earth Leakage)

When internal insulation degrades, electricity 'leaks' to the ground, causing safety breakers to trip and potentially damaging the controller.

Incorrectly Sized Expansion Vessel

An expansion vessel cushions pressure changes. If it is too small, the system will experience violent pressure spikes and frequent pump starts.

Pump Vandalism or Theft Risk

Borehole and booster pumps are high-value targets for theft. If the installation is not secured, the system is vulnerable to tampering or removal.

Inconsistent Water Temperature (Pressure Surges)

Temperature swings are caused by unstable pressure. When pressure changes, the mixer cannot maintain a consistent blend.

High Electricity Consumption from Pump

Frequent cycling or poor system balance causes pumps to consume far more energy than necessary.

Noisy Check-Valve (Water Hammer Slam)

When water slams back against a valve, it creates a shockwave that stresses the system and damages fittings.

Electrical Surge or Lightning Damage

Power surges can damage both control electronics and motor windings. The system may fail suddenly after a surge event.

Suction Line Cavitation

Cavitation happens when the pump cannot get enough water on the suction side. Air bubbles form and collapse, damaging the pump internally.

Lime-Scale Build-up on Pump Impellers

In hard water conditions, scale builds up inside the pump. This increases resistance and can eventually stop the motor from turning.

Foot-Valve or Check-Valve Failure

A failed check valve allows water to drain back into the source. The system loses pressure and must re-prime every time the pump starts.
