Whole-house repipe
New supply lines to every fixture are what a whole-house repipe delivers, and the route they take through your walls and floors is planned first. Talk through your home’s layout when you call.
Repiping and Water Line Replacement in San Jose
Replacing the supply pipes in a house, or the line running in from the water meter, is a bigger job than a repair. Call to talk through what your home needs and what the work involves.
We cover whole-house and partial repipes, new water lines from the meter, and the choice of pipe material. The notes below explain the City’s permit rules and your water retailer.
Repiping choices
Partial repipe
A single failed run, such as the pipe feeding one bathroom, can be replaced on its own as a partial repipe. Say which run is failing and you hear whether that suits your house.
New water line from the meter
The water service line is the stretch from the meter to the house, and replacing it is its own job apart from interior repiping. When you call, say what is wrong with yours and the plumber you hire picks it up from there.
Choosing the pipe material
PEX and copper are two materials plumbers choose between for supply lines. The plumber you hire sets out the options for your house and what each involves.
Two kinds of repipe
San Jose splits the work into two jobs. An interior repipe replaces the water lines inside the home, and a water service project means repiping the exterior lines from the house to the water meter.
Pipe repair and the permit behind it
A plumbing permit is required for a repipe or water service project in San Jose. The same permit covers repiping, water service and water heater replacement as needed.
A building permit is also needed if shear walls, firewalls or any structural member are affected, and that job comes with plans.
Frequently asked questions
Does my water retailer matter for lead pipes?
Yes, it depends on your retailer. The San Jose Municipal Water System says it has no lead service lines, private side included. San Jose Water Company says it has none either, though some homes potentially have a lead gooseneck.
