A guide can help you shut off water, spot a failing part or know what to ask. It cannot see inside a wall or a buried pipe. When the symptom is active water, repeating clogs or no hot water, move from reading to calling.
Some signs mean you should stop trying fixes. A tub gurgling when another fixture drains, sewage in a floor drain, or a hot water tank that is leaking or hissing all call for a plumber. Shut the water off and call for sewer line cleaning, water heater repair or a burst pipe fix.
Repeated slow drains often point past the fixture. A plumber can use drain cleaning, then hydro jetting if grease or roots are packed in. A camera through sewer inspection shows what is actually in the pipe.
If your water bill has jumped or your meter keeps moving with everything off, leak detection finds the pipe without opening the wall. If the pipe turns out to be failing across the house, the plumber can explain whether repiping is worth it.
Gas is the exception to everything here. If you smell gas, leave the building, call 911, then call Pacific Gas and Electric. A plumber is not the first call.
Whatever the job, ask for a clear price before work starts. Our licensed and insured plumbers explain what they find, then you decide. You can also see the full list on our services page, or find your town on the areas page. Our guides point to the California Plumbing Code, which is based on the Uniform Plumbing Code (UPC) and to utility guidelines where they apply.
