How we repair a foul water pump
Make it safe
We check the chamber level and the electrics first, so the system cannot back up or trip again while we work.
Find the cause
We check for blockages, floats, non-return valves, junction boxes and the control panel.
Repair or replace
You get a free written quote before any work starts. We repair what can be repaired and fit a new pump where it cannot.
Test and report
The pumps are tested in automatic and you get a report with photos.
What commonly goes wrong
On our recent jobs we have found rag and wipes wrapped around pumps and floats, tree roots catching the floats in a chamber, wet junction boxes, failed non-return valves and broken float brackets. Each one can stop a pump or make it trip, and each is something an engineer can find and fix.
We work on all makes of foul water pump, and we are independent. We recommend the pump that suits your system.
