"Juan came to the house and installed a new gas valve controller for my RHEEM water heater. He honored his over the phone price quote, and did a great job. He even checked my water pressure. No run-around here, just the honest truth from True-Blue Plumbing."

"We have worked with many plumbers in Los Angeles, and our experience with GMC Plumbing was by far the best. They are responsive, honest and trustworthy. They did a great job and helped us avoid paying the thousands of dollars other plumbers told us would be needed to fix the problem. We highly recommend them"

"I was skeptical at first of using HomeAdvisor to get more bids for work on our residential sewer lines but went ahead and accepted a connection with So-Cal Plumbing & Rooter. Jose called me immediately and his partner Alex and crew were here within half an hour. They did a thorough job diagnosing our issue and provided the most reasonable and fair bid we've seen. Once we accepted their offer, they began working straight away and returned in the morning to complete the job. We couldn't be happier with the experience and are grateful to Jose & Alex for their professionalism, honesty and thorough work. They will be our go-to plumbers from now on!"

"I recently had a gas leak scare and called L.A. Plumbing pros. He was fantastic! The plumber who came out his name was Victor he was professional, communicative, and very efficient. He was able to quickly locate the source of the gas leak and explained everything clearly throughout the process. I felt confident in his expertise and appreciated his willingness to answer all my questions. The repair itself was done promptly and the work area was left clean afterwards. I highly recommend L.A. Plumbing pros for any plumbing needs, especially if you suspect a gas leak. Their fast response, clear communication, and quality service were all top-notch!"

"OMG. I couldn?t have found a more professional plumber than Johnathan. He was on the job within minutes. He swapped out my kitchen sink faucet in record time. Just an unbelievable, honest and thorough plumber. He was reasonably priced and he exceeded my expectations times 10 over. I would not hesitate to recommend Jonathan for your plumbing needs. You won't be sorry."

Plumbing FAQs, answered by experts

A shower cartridge is a component located inside the shower valve. While the terms are sometimes used interchangeably, they are two different parts. The shower valve is the entire device that regulates the flow and temperature of water in your shower. The cartridge is the inner part of the valve that connects to the shower controls, allowing you to adjust the water's temperature and flow by balancing the mix of hot and cold water. While the signs of a failing valve and cartridge can be similar, if you are experiencing issues with water temperature, you may need to replace the entire valve.

Installing a clawfoot tub with a minimum of 6 inches of clearance from surrounding walls allows ample room for the faucet and pipework, makes cleaning easier, and reduces the chance of moisture being trapped between the tub and the walls. It might need to be closer if the faucet comes directly out of the wall.

Yes, insulating your pipes can reduce plumbing noises because it dampens vibrations and reduces the transmission of sound, making your home a quieter place. So if you've ever been annoyed by the sounds of water rushing through your pipes or the clanging noises when someone turns on the faucet, insulation can help.

No, you can’t drain your sump pump into your home’s sewer system. In fact, it’s against the law in many places because dumping extra water into a municipal water system can disrupt or overwhelm the treatment process. And for similar reasons, you shouldn’t discharge a sump pump into your septic system, either.

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.
