Frequently asked questions
Does replacing a faucet require a permit in Ontario?
Replacing an existing faucet in the same location typically does not require a permit. New rough-in plumbing or changes to the drainage system do require a permit.
How do I shut off water in an emergency?
Find your home's main water shutoff valve — usually in the basement near where the water line enters the house. Turn it clockwise to shut off.
What is a backwater valve and do I need one?
A backwater valve prevents sewer water from flowing back into your home during heavy rain. The City of Toronto offers a subsidy program for installation — check toronto.ca/subsidies for current rates.
