Backwater Valve Installation
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 in 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 until 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 of 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 at the time of new construction plumbing, as a trench will have to be dug out that is 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. Plumbing retrofit was encouraged for those in ‘risky’ areas, but not in all cases do the government by-laws require backwater valve installation just yet. Some insurance companies, however, will not pay for damages in certain homes if a backwater valve is not fitted and in working order. As the climate is changing and more heavy rain storms are predicted in the future, it is a good idea for every home to install a backwater valve, if not solely for peace of mind.
The amount of water going into the city drains might be affected by the current weather dramatically. During rainstorms and snow melting, city drains are overloaded trying to redirect all the water away. As a result, we might face such problem as water backing up from the drains and typically water moves to the lowest point, which very luckily might be you basement. To prevent your property from that kind of disaster, installation of a backwater valve is highly recommended. The backwater valve is device that allows water to go only in one direction – out of your house toward to city main drain. At the moment the city drain is overloaded and water trying to go backwards into your house, the backwater valve will close automatically, protecting your property from the potential disaster.
