“Sump and backwater valve installed the week before the big August storm. Neighbours on both sides took water and our basement stayed completely dry.”

London Plumbing Pros: Sump Pumps & Backwater for London and Middlesex homes.
Why Homeowners Call Us
One storm from a finished basement full of water?
London Plumbing Pros builds basement flood protection in layers, from a properly sized pump to a backwater valve on the sewer line.
Pumps Matched to the Weepers
Foundation drainage in London clay belts moves serious water in a storm. We calculate head and flow so the pump you buy cycles normally and still has margin when the rain gets serious.
Backup That Runs Without Hydro
The pump is useless in the outage that accompanies the storm. Battery systems and water-powered backups keep the basin empty through the blackout hours that flood other streets.
Backwater Valve and Subsidy Paperwork
Installing the valve is one step, and documenting it for municipal flood-prevention subsidy programs is another. We install to code and hand you the paperwork to file.

What London Homeowners Say
Real feedback from neighbours we've helped stay comfortable year-round.
“Rental tank was seventeen years old and still on the monthly bill. They bought it out and had an owned unit in the next morning. Should have done it years ago.”

“We manage student units near Western and they swapped four toilets between semesters. Tough fixtures, tidy work, one invoice. Our go-to now.”
