Backwater Valve Installation

Backwater valves are a must-have for most buildings. These valves protect your home from a back-up of sewage from the city’s main sewage pipes. If there is a block in the main sewage line, it will take some time before the community is aware of it. During this time, people will continue to flush toilets and run faucets. After a while, the sewage has no place to go but back up the sewage lines – into your home. A backwater valve will prevent this from happening. In other words, it means that sewage can only go one way – out of your home.


Some contractors will tell you that backwater valve installation is only necessary if the lowest finished floor in your home is less than one foot above the uphill manhole cover for the public sewage system. However, it is a good idea for any home to have one. A clog in the main pipe can happen anywhere – putting any home at risk, regardless of where it’s situated.


Backwater valve installation should be completed when a building is being newly constructed. The technicians will need to dig out a trench 2 to 3 feet wide to install the backwater valve. However, if you require a backwater valve installation, it can be done at any time by a professional plumbing company.

Sewage flooding can also occur during massive rainstorms, like in 2012 across Manitoba, Ontario, and Quebec. Not all government by-laws require backwater valves just yet. However, some insurance companies will not pay for damages in individual homes if there is no functioning backwater valve installed.

As the climate changes, more torrential rainstorms will dramatically increase in the future. The amount of water going into the city drains will be affected by that change in weather significantly. During rainstorms and snow melting, city drains overload with water, debris, and sewage. The drains unsuccessfully try to redirect all the water away. As a result, we face backed up drains.

Typically water moves to the lowest point. Unfortunately, that lowest point could end up being your basement. To prevent your property from disaster, install a backwater valve. The backwater valve will close up if water backs up, keeping you and your house safe from serious damage.
