Read about itMountain View, CA · Answered 24/7
Mountain View sits at the northwest edge of our regular area. Its water is mostly Hetch Hetchy, and its older neighborhoods have the galvanized pipe problems you would expect.
Mountain View is in our regular service area from the North San Jose office, and phones are answered 24/7. About 87 percent of Mountain View's water comes from Hetch Hetchy through the San Francisco PUC, so scale is less of a problem than in well-water cities, while older homes in Old Mountain View still carry failing galvanized pipe.
About 87 percent of Mountain View's drinking water comes from the San Francisco Public Utilities Commission, mostly from Hetch Hetchy, about 10 percent from Valley Water, and about 3 percent from city wells. Small parts of the city are served by California Water Service instead.
Hetch Hetchy water is soft compared with groundwater, so heaters and fixtures usually see less scale here than in well-supplied cities. That changes what we recommend: a softener is often unnecessary, while routine water heater maintenance still pays off.
Most Mountain View homes built before 1970 were plumbed with galvanized steel, and Old Mountain View has a high concentration of galvanized failures. Even with soft water, galvanized pipe rusts from the inside, so pressure drops and water runs brown after sitting. A whole-house repipe is the lasting fix.

Mountain View is the northwest edge of our regular area; Palo Alto and the Peninsula beyond are further than we normally go, so call and ask first from there. For Mountain View itself, we handle everything from drain cleaning to sewer line repair.
