Parts people actually search
Pressure vessel (bladder tank)
Waterlogged vessel = pump starts every few seconds. We check pre-charge before selling a new pump.
Electrode / level probe
Roof and basement tanks. False dry / false full. Pair with transfer pump.
Relay & contactor
Welded contacts, chatter, overload trip. The smell of burnt bakelite is a panel job, not a wet-end job.
Timer
Duty-standby rotation, star-delta, delay-on. Stuck timer = one pump forever. Related: diverter / MOV.
PCB / controller board
Quoted from the part number on the board. We do not pretend to have every OEM card in the van.
Motorised valve
Actuator, limits, 24/230V. See the diverter page.
Float switch
Sump and ejector pits. Tangled floats look like a dead submersible. Sump · ejector.
Game-changer: send three photos
- Pump nameplate
- Panel door open (contactors + PCB)
- The fault (gauge hunting, alarm, overflow)
That is enough to separate a S$60 switch from a S$2k pump. Independent service — not authorised dealer stock for any brand. See brands.
Parts FAQs

Yes. Labour from S$60. Switch unit and GST extra. Quoted before we fit.
Can you rewire a burnt panel?
Often. If the enclosure is cooked we quote a replacement controller, not a mystery PCB.
