Backwater Valve Installation Toronto to prevent Basement Flooding

Have you ever imagined raw sewage spewing out of your sink, shower stalls or toilets? With many parts of the country recording high precipitation, such unfortunate occurrences have been experienced by some families. These kinds of backflows have their setbacks. They lead to damage that will prove a challenge to repair and also result in massive health hazards.

The sanitary system of most homes is eventually connected to the sewer system that the municipality manages.

Why do backflows occur?

One of the several reasons why backflows happen is because some homes have combined sanitary systems and the storm water systems. Therefore, after the water has been collected in the gutters, it is usually discharged into the sanitary system. The other factor that may cause the increase of water level could be illegal connections.


When heavy rain falls, the sanitary main may get filled to such levels that it is no longer able to hold. This eventually makes it drain off because the increased volume can no longer be handled.

Water will always want to follow the path that has the least resistance. It will tend to flow back, going even through the narrowest opening. Such openings can be found in the floor drain or any other lowest located plumbing drain in the home. And this leads home owners to ask themselves an important question: how can I prevent sewer backflow?


As troublesome as the question could be, you do not need to worry too much because there are solutions available. Two devices can assist you in reducing excess water in the basements and pipes. These are the backwater valve system and the overhead sewers. New Drain experts can implement either of these systems for the benefit of your home.

How Backwater Valve Prevents Flood

How does Backwater Valve System work?

The first solution for backflow prevention is to use a backwater valve system on the sewer line. This kind of valve has a horizontal check valve that is designed in such a way that waste will flow in only way. A metal disc in place opens as waste flows forward and then closes as it tries to come backward. It is suggested to install a basin in front of the check valve at the waste collection place. There is then a pump that forces the waste past the valve into the sewer line.


Annual maintenance is a necessity so as to lubricate the hinge disk. Keep in mind that debris in the sewer line will cause failures.

Overhead sewer system

The overhead style is usually an even better option that you can use as an alternative. As per your existing layout, the lower sanitary level can be separated into a sanitary pit. The waste discharge is then pumped into the sanitary system. Since the pump and the sanitary pit are installed indoors, the maintenance that is needed is less. The chances of the service line getting stuck are minimal since there is no installation to it.
