What we handle

If it pumps, we look after it

From a cellar sump to a full pumping station — installed right, serviced on schedule, repaired fast.

Sump pumps

Basement and cellar sump systems installed, repaired and kept ready for the next downpour.

Sewage pumps & stations

Domestic and commercial pumping stations — new installs, refurbishments and fault-finding.

Booster pumps

Low water pressure fixed with correctly sized booster sets, fitted and commissioned properly.

Emergency pump failure

Pump stopped and levels rising? We’re on call 24/7 to repair or swap it before it becomes a flood.

Servicing & maintenance

Planned pump servicing that catches worn floats, blocked impellers and tired motors early.

Controls & float switches

Control panels, alarms and float switches tested, repaired or replaced so the pump runs when it must.
