Non-Return Valve Installation
It is critical to install a non-return valve to prevent the backflow of sewage after a heavy rain shower. If the construction of your property is less than 40 years old, it is probably already equipped with a valve. However, this is not necessarily the case for older buildings.
The installation of a non-return valve, also known as a backflow preventer, requires the expertise of a plumber who is a member of the CMMTQ.
