Basement protection

Backwater Valve Installation in Mississauga

During a storm, once the city main backs up, water seeks the lowest opening it can find. A backwater valve closes that door.

  • Your basement has a floor drain, toilet, shower or laundry connected to the sanitary line
  • Neighbours have experienced sewer backups during heavy rain
  • A basement finish is planned and deserves protection
  • Your insurer asks about backflow protection at renewal

How we do the work

  1. Camera the lateral to confirm the pipe is in good condition where the valve will sit.
  2. Apply for the permit. Installation in the main line generally needs a City of Mississauga plumbing permit.
  3. Open the floor at the point where the main drain leaves the house.
  4. Install a normally open valve so that household drains still flow freely and the flap closes only on reverse flow.
  5. Leave a removable cover over the valve for later cleaning.
  6. Arrange inspection and restore the floor.
An important caution. With the flap shut, your own drains cannot empty either. During a storm warning, avoid laundry and long showers.

Mississauga homes and this job

The Region of Peel and the City have, at various times, offered subsidies for backflow devices and other flood measures. Eligibility and amounts are revised, so read the present terms first. Older homes where the weeping tile connects into the sanitary sewer may benefit from pairing the valve with a sump pump so that foundation water is pumped out separately.

What affects the cost

  • Depth of the main drain below the slab
  • Finished flooring that must be removed and replaced
  • Whether the weeping tile must be disconnected at the same time

Once installed, simple twice-yearly care keeps the valve reliable; see backwater valve maintenance. Some owners schedule this work alongside a water heater replacement while the basement is already disrupted.

Answers our Mississauga crew gives most

Will the valve keep every kind of water out?

It answers only sewage backflow. Seepage and runoff are handled by grading, eavestroughs and a sump.

How long does installation take?

Typically a day of work, plus the permit inspection.

Can I install one myself?

A permit and inspection are usually required, and the work is normally done by a licensed plumber.
