Backwater valves are a must-have for some buildings, and a should-have for all. These valves are put in place to protect your home from a backup 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.
Which Homes Require Backwater Valve Installation?
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 sited.
When Should You Install a Backwater Valve?
Backwater valve installation is best done when a building is being newly constructed. That’s because a trench will have to be dug out that’s about 2 to 3 feet wide in order to install it. However, if you require backwater valve installation, it can be done at any time by a professional plumbing company.
Sewage flooding can also occur during massive rain storms, as occurred 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 certain homes if there is no functioning backwater valve installed.
As the climate changes, more heavy rain storms are predicted in the future. The amount of water going into the city drains will be affected by that change in weather dramatically. During rainstorms and snow melting, city drains are overloaded, trying 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 that kind of disaster, installation of a backwater valve is highly recommended. It will close up in the event that water backs up, keeping you and your house safe from serious damage.
