We replaced the sewer line at this Highcliff Crescent property in Scarborough, covering the connection from inside the house to the exterior property line. The trenchless installation method reduced the need for continuous excavation along the replacement route. As part of the work, we removed the old clay building trap and installed a backwater valve. The new sewer line updates the property's drainage infrastructure, while the valve helps protect against reverse sewage flow during a sewer backup. Completing these improvements together addressed aging drain components and added backup protection in one project, renewing the connection that carries wastewater away.
