24/7 Emergency Plumber in Milpitas, CA

A Homeowner’s Guide to Emergency Plumbing in Milpitas

First steps, in order

1. Stop the water. Close the fixture valve, or the main shutoff where the water line enters the house. For a leaking water heater, close the cold water valve on top of the tank and turn its gas control to off, or switch off its breaker.
2. Keep away from electricity. Stay clear of water near outlets, appliances and the panel.
3. Stop using drains if sewage is coming up, the washer and dishwasher included.
4. Gas smell: leave first, then call 911 and PG&E.
5. Call us at (408) 978-3093, any hour. We’ll tell you honestly whether it needs a plumber tonight or can wait for a regular appointment.

Who to call in Milpitas

Milpitas provides its own water and sewer service, so a problem on the street side goes to the City, not a water company or sanitary district:

• Weekdays, 7 a.m. to 5 p.m.: Public Works, 408-586-2600.
• 5 p.m. to 7 a.m., weekends and holidays: Police Dispatch, 408-586-2400. For a sewer spill, the City also lists 911.
• Gas: 911, then PG&E at 1-800-743-5000.
• Anything on your side of the meter or the property line: a plumber. That’s us.

The water service line runs from the main through the City meter to the house; the pipe from the meter to the house is private, and replacing it is done under a City plumbing permit. See water line replacement.

Burst pipes and high pressure

The City says water pressure in Milpitas ranges from 40 to 140 psi, depending on location. Its handouts follow the plumbing code: above 80 psi a pressure regulator with a strainer is required, and where a regulator, check valve or backflow preventer is installed, the water heater needs an expansion tank. When a regulator wears out, the full street pressure reaches every hose, valve and water heater in the house, so a burst supply line in a high-pressure neighborhood is worth a pressure check, not just a new hose. See burst pipe repair and leak detection.

Most Milpitas homes date from 1970 or later; the City’s 2015 Housing Element put the median at 1977. The older ones are more likely to have galvanized pipe that rusts from the inside. For hidden leaks, the City’s WaterSmart portal can send leak alerts.

Sewage backups

The City splits the side sewer at the property line. The House Sewer, from the house to the property line and its cleanout, is the owner’s to maintain and clear. The House Lateral, from there to the main, is public: when a broken pipe or other structural failure there causes the stoppage, the City repairs it at no charge. If the City is called out and finds grease, rags or no stoppage at all, the user pays its costs. We clear the line from the property-line cleanout by cable or hydro jetting. See drain cleaning in Milpitas and sewer line repair in Milpitas.

Water heater and gas emergencies

Any water heater replacement needs a plumbing permit. At a single-family home or duplex, a same-type replacement in the same place can be permitted online in eTRAKiT as ONL WATERHEATER, and a gas-to-heat-pump swap on a new circuit without a panel upgrade as ONL HP WH. Water heaters need seismic strapping, and a drain pan where a leak would cause damage. Silicon Valley Clean Energy’s Emergency Water Heater Replacement program works through SVCE partner contractors. See water heater service in Milpitas.

For gas, PG&E comes first. Repairs that alter or add to an existing gas system must include a seismic or excess-flow gas shutoff device after the PG&E service tee. See gas line services and all our plumbing services in Milpitas.
