Backwater Valve Installation
Due to heavy rain falls in Toronto, city sewer lines can become overwhelmed, and it will cause water or sewage to flow back towards your home. However if there is a sewer system backup, and you have a backwater valve in place, sewage will not be able to flow back into your house.
In this project, backwater valve has been retrofitted to an existing house. Installing during the initial construction is certainly much cheaper; when retrofitting to an already built house, some concrete will need to be removed to access main sewer line and this will therefore increase the cost to some extent.
