Emergency Plumbing Services

Nights, weekends and holidays, for homes, HOAs and businesses.

  • Burst and leaking pipes

    We stop the water, find the break and repair it. See burst pipe repair.

  • Sewer backups

    Main lines cleared from the cleanout, by cable or jetter, and the cause found.

  • Overflowing and clogged toilets

    Especially when it's the only toilet, or water is reaching other rooms.

  • Water heater leaks and failures

    Leaking tanks shut down safely and replaced, often the same or next day.

  • Gas line leaks

    After PG&E has made it safe, we find and repair the leak. If you smell gas, leave and call PG&E or 911 first.

  • Main water line breaks

    Water bubbling up in the yard or no water at all. See water line repair.

Is It a Plumbing Emergency?

Call right away for these. Smaller problems, like a dripping faucet, can wait for a regular appointment and save you the emergency rate.

  • Water you can't stop

    A burst pipe or failed supply line, especially if the shutoff won't close.

  • Sewage backing up

    Wastewater coming up in a shower, tub, floor drain or cleanout.

  • Water near electrical

    Leaks near outlets, light fixtures or the panel. Stay clear and turn off power only if it's safe.

  • No water

    Loss of all water, often from a main line break or a failed main valve.

  • A leaking water heater

    Water around the tank, or a relief valve discharging continuously.

  • Gas smell

    Leave first, call PG&E or 911, then us.

What to Do in a Plumbing Emergency

  1. Stop the water. Close the fixture shutoff (behind the toilet, under the sink) or the main shutoff for the house. For a water heater leak, close the cold water valve on top of the heater and turn the gas to “off” or switch off its breaker.
  2. Stay safe. Keep away from water near outlets, appliances and the electrical panel. If you smell gas, leave and call 911 or PG&E from a safe distance.
  3. Stop using drains if sewage is backing up, including toilets, sinks, the washer and the dishwasher.
  4. Call us at (408) 978-3093. We’ll talk you through anything else you can do safely.
  5. Document the damage with photos for your insurance before cleanup.

Emergency or Next-Day Appointment?

Emergency service costs more, so we’ll be honest about whether you need it. A running toilet, a dripping faucet or a slow drain can usually wait. Water you can’t stop, sewage in the house, a gas smell, no water or your only toilet out of service shouldn’t. Often we can make things safe tonight and finish the repair the next business day at the standard rate.

Be Ready Before It Happens

  • Find your main water shutoff and make sure it turns; replace it if it’s seized.
  • Label the water heater’s gas valve or breaker.
  • Know where your sewer cleanout is.
  • Save our number: (408) 978-3093.
  • Consider a service plan for priority scheduling.

  • Our HOA manager recommended CPI when our toilet overflowed on a Saturday evening in July. They picked up the phone at 8:30pm on a Saturday night. One of their plumbers showed up 30 minutes later. He quickly determined that the clog was a bigger issue further down the sewer line which required a professional hydro jetting cleaning to resolve. After checking with the HOA manager, CPI sent a jetter machine and another plumber within half an hour. Their crew worked until 11:30pm to clear the clog. We were so happy that we could use the bathroom again! CPI was responsive, communicated well, worked fast, and resolved the issue during off-hours. We will definitely call them again.

  • I called your emergency number first thing Saturday morning and Dustin called me right back. He went out there late morning and found a hole in the drain pipe and a backup nearby that was making the leak even worse. He snaked the line and temporarily patched the line so gases wouldn’t escape. He said I would need to get restoration out there to (again) dry out the crawlspace before CPI could replace the drain pipe. It is plastic not cast iron apparently.

    Dustin was really great, communicative, and helpful. Really appreciated his work.

  • Danny fixed a broken flange before a water meter that had caused a huge water geyser. He was calm and put in a new flange quickly and effectively. Love working with Danny, who is skilled, knowledgeable, and friendly!

How much does an emergency plumber cost?

Most emergency repairs are quoted as a fixed price before we start. Night, weekend and holiday prices are typically based on $200 to $300 an hour plus parts and drive time, with a minimum charge.

What should I do while I wait?

Shut off the water at the main valve or the fixture, stay away from water near electrical, stop using drains if sewage is backing up, and move belongings out of the way.

Can a plumbing problem wait until morning?

If you can stop the water and it's not affecting electrical, sewage or your only toilet, waiting for a regular appointment saves the emergency rate. We'll help you decide on the phone.

Yes. We respond to after-hours calls for restaurants, offices, condo complexes and apartment buildings.
