Do you know how your sump pump is installed? We’ve seen all sorts of sump pump installations over the years, configured in different ways and discharging to various locations.
Sump pumps connected to a sanitary sewer contravenes Ontario Building Code. This practice could overload waste water treatment plants. As a result, a sump pump should discharge either to a dedicated storm sewer if available, or better yet, to the lawn at least 2 metres away from the home to prevent penetration back into the building.
Sump pump discharge pipes require a check valve to prevent water in the pipe above the sump pump from coming back into the house after the pump shuts off. The length of discharge pipe should be as short as possible to reduce pump stress. Sump pumps should also be on their own dedicated electrical circuit. in the event of power interruption, a battery back-up is advisable.
