Mostly Hetch Hetchy

The city says it buys about 87 percent of its water from the SFPUC, about 10 percent from Valley Water and the rest from local wells, and it has been working on a purification plant to cut reliance on San Francisco supply. Check the city for any notice or restriction. Pipes beyond the meter, inside and out, are your responsibility.

Postwar Ranch Homes

Many Mountain View homes date to the 1950s and 1960s. Expect galvanized supply, cast iron drains and clay laterals. Ask for a written inspection ahead of a sale or remodel; it shows what is still original.

Soft Water and Scale

Hetch Hetchy water is soft, so scale is lighter than in valley groundwater, but heaters still collect sediment. Flush the tank yearly.

Condos, Apartments and Tech Housing

Mountain View has many condos and apartments where walls and stacks are shared. Ask who owns each part of the plumbing and where the unit shutoff is.

Bracing Your Water Heater

A loose heater can tip and tear its own water and gas lines. Look for two straps, flexible water and gas connectors and a gas shutoff you can reach. An automatic gas shutoff valve is worth asking a plumber about.

Meter Test for Hidden Leaks

Pipes in slabs and walls leak quietly. Musty smells and cracked grout can also point to water below. Finding the exact spot keeps the repair small. Emergency plumbing is there for leaks that cannot wait.

Drains and Roots

Backups that return after cleaning usually mean roots, a belly or a cracked pipe. A locator marks the spot so any repair stays small. Simple clogs call for drain cleaning; a cracked or collapsed line calls for sewer line repair.

Stops and Supply Lines

Flexible lines and shutoff stops wear out quietly. Press on the line gently and look for beads of water at the nut. A plumber can swap them quickly and test for leaks.

Quick Checks Before You Call a Plumber in Mountain View

Clean the aerators. Unscrew the tip of each faucet, rinse out grit and soak it in vinegar for an hour if there is white crust. Low flow at a single faucet is often just a clogged aerator rather than a plumbing fault. If flow is still weak after cleaning, mention it when you call, because a partly closed stop valve or a worn cartridge may be the cause of the problem.

Before a long trip, turn off the main, open a faucet at the lowest point to drain the lines and set the water heater to vacation or pilot. Ask a neighbor to check the home, and tell them where the shutoff is. A burst supply line in an empty house can run for days, which is why many Mountain View insurers recommend shutting off water when you leave for more than a few days.

Be careful with chemical drain cleaners. They can damage older pipe, harm a septic system and burn skin and eyes, and a bottle left in a standing sink makes the next repair hazardous. A strainer, hot water, a plunger or a professional cleaning is safer for the pipe and for the person who does the work. Tell the plumber if you already used any product.

Flush the water heater once a year if it is a tank model. Turn off power or gas, connect a hose to the drain valve and run the water until it clears. On an old tank that has never been flushed, ask a plumber first, since moving old sediment can expose leaks. Regular flushing slows scale buildup and keeps the burner or elements working efficiently for longer.

If you rent, tell the landlord or manager about a leak in writing, even if you also call a plumber. Keep copies of messages and photograph the damage. Know where your unit’s shutoff is, and ask who is authorized to call a plumber. Clear communication protects your deposit and your belongings, and it makes sure the right person pays for the repair.

When to Call Right Now — and When It Can Wait
