Basement flooding and sewer backup in Winnipeg

Plumbers for backwater valves, sump pumps and drains.

26 pros in Winnipeg

These plumbing and drain contractors work in Winnipeg and say on their own websites that they install backwater valves, sump pits or sump pumps. Two local points before you hire. The City says homes built after 1979 had to have a backwater valve and homes built since 1990 a sump pit, so an older house may have neither. And only a City-licensed contractor can take out the plumbing permit, which is the record that shows the job was authorized.

Questions about hiring in Winnipeg

Who can install a backwater valve or sump pit in Winnipeg?

A plumbing contractor licensed by the City of Winnipeg. The City says this work can only be done by a licensed contractor, who must also apply for the permit. Being on the City's licence list doesn't show that your job has a permit, so ask for the permit number and check it before the work starts. City of Winnipeg (source, opens in a new tab)

Does my house already have a backwater valve?

The year it was built is a clue. The City says homes built after 1979 had to have a backwater valve, and homes built since 1990 a sump pit drainage system; some older homes had them added later. If you can't tell, the City suggests asking a licensed plumber to look. City of Winnipeg (source, opens in a new tab)

What should a written quote include?

The exact work: how many valves and where, the pit and pump model, the discharge line, and how the basement floor will be patched afterwards. It should also name who gets the permit and books the inspection, the start date, the payment terms and the total price. Ask each contractor to quote the same job so you can compare them.

How do I compare quotes?

Get at least three and compare like with like: the same valve type, the same pump and pit, the same discharge route and the same floor repair. Check that each business is on the City's licensed contractor list, ask for references from recent jobs, and get any promise about timing or clean-up written into the contract.
