Backwater Valve Installation in Toronto

When the sewer backs up in a storm, a backwater valve closes so the water can't come up through your basement floor drain. It goes on your main sewer line, with the building permit the City requires, so the work counts for the City's subsidy.

Diagnosis, price, then the work

  1. Diagnosis

    You call, describe what you see, and we find the cause on site.

  2. Free estimate

    The estimate is free. You hear the price before any work starts, and it doesn't change without your OK.

  3. The work

    We fix it, test it, and show you what was done.

What we don't do

We don't install a backwater valve without the building permit. The City requires one, and the subsidy is only paid for permitted work, so you never end up with a valve the City won't count.

Backwater valves: common questions

How much is the Toronto subsidy for a backwater valve?

The City of Toronto pays up to 80% of the invoiced cost, to a maximum of $1,600 per valve, for up to two valves. The whole program covers up to $6,650 per property. Check the conditions on toronto.ca before the work starts.

Do I need a permit for a backwater valve in Toronto?

Yes. The City requires a building permit to install a backwater valve, and the subsidy needs it too.

Who can apply for the subsidy?

The registered owner of a single-family home, duplex, triplex or fourplex in the City of Toronto. Outside Toronto, Markham, Vaughan, Peel Region and Mississauga run their own programs: see their area pages.

Does a backwater valve need maintenance?

Yes. Open the access cover about once a year, check that the flap moves freely, and clear out any debris so it can close when it has to.
