Why is my booster pump tripping the circuit breaker?

A pump that trips the main breaker is often seized, shorted, or drawing high current from a failed capacitor or pressure switch. An electrician may point to the pump — we survey the pump, switch and wiring together so you are not bounced between two trades.

Do you do ejector pits and AJ jetting as well?

Yes. Ejector pit pumps and AJ (high-pressure) jetting are quoted by the same AOT team. See the ejector pit and AJ jetting page for that scope.

HDB BTO low water pressure — do I need a booster?

Sometimes. After a storage heater swap or HIP, undersized 15 mm pipes and a weak incoming main can make showers intermittent. We survey first; the fix may be pipe upsizing, a small booster, or both.

Pressure problems we actually see

One trade for the pump, switch and wiring

Landed houses often call after an electrician says the booster is tripping the main breaker and rooms still have intermittent pressure. HDB BTO and HIP units call after swapping to a storage heater and finding the shower still weak. We survey the pump, pressure switch, pipes and isolator together.
