West Seattle neighborhoods such as Admiral, Alki, and Delridge include many homes with underground water lines that may be decades old. Over time, older service lines can corrode, shift, or develop leaks underground. Homeowners may notice low water pressure, unexplained wet spots in the yard, or unexpected spikes in their water bill. Installing a new water main line connection can restore reliable water service and prevent future problems. Our plumbing team helps West Seattle homeowners evaluate their existing line and install a new supply line designed for long-term performance. In some cases, installing a properly sized water pressure regulator can also help protect the new line and maintain stable pressure throughout the plumbing system.
