Your home’s water main is the underground pipe that brings water from the city’s supply to your house. You probably don’t think about it much—until there’s a problem.
For this home in Seattle’s Leschi neighborhood, JT Plumbing NW replaced the existing water main using a trenchless water main replacement, a method that allows a new water line to be installed with significantly less excavation than a traditional replacement.
Older Seattle homes can have water lines that have been underground for decades. Over time, pipes can corrode, develop leaks, become restricted by buildup, or simply reach the end of their useful life.
Signs of a water main problem can include low water pressure, unexplained increases in water usage, wet areas in the yard, discolored water, or a noticeable loss of water pressure throughout the house.

Trenchless replacement isn’t right for every property, but when conditions allow, it can mean a faster, cleaner water main replacement with less impact on the home and surrounding landscape.
JT Plumbing NW can evaluate an existing water main, identify the cause of the problem, and recommend the right replacement method for the property. For this Leschi homeowner, trenchless technology meant getting a new, reliable water main without unnecessarily tearing up the property to get it there.
