A home expansion and the addition of multiple bathrooms increased water demand at this Morden Road property in Oakville. We upgraded the existing 5/8-inch water service to new 1-1/4-inch Type K soft copper piping. The larger incoming water line provides additional supply capacity for the expanded home and its added plumbing fixtures. This project addressed the service connection as part of adapting the property's plumbing to its changed requirements. Replacing the smaller line gives the home a larger copper water supply connection, supporting the increased demand associated with more bathrooms and preparing the service for the expanded residential plumbing layout.
