"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 searched for a plumber yesterday and he was the first to call and respond to my need. He came on time, he knows what to do, very responsive to inquires via phone or text. Amazing, professional worker who won't price gouge or try to upsell you. Recommendable! Thanks Kenny!"

"An extremely informed, and very hard-working plumber. The work when completed was very fine. we would highly recommend him to anyone who might need a first rate plumber. Mr. Chajon, though still young, has absorbed the knowledge and craftsmanship of a professional twice his age. You should consider him a bargain."

"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!"

Affordable Plumbers FAQs, answered by experts

When a dishwasher discharges its wastewater, it uses a pump to quickly move a lot of water. If anything in the drain line or the garbage disposal impedes the high volume of water, it will back up into the sink through the drain or the garbage disposal. Following regular dishwasher maintenance tips like clearing clogs, keeping them cleared, and occasionally running the disposal will eliminate the problem.

In most cases, a dripping faucet will not stop on its own. Dripping usually occurs because of a failed cartridge or broken washers. Normal wear and tear eventually runs these parts down and causes the faucet to drip when you've already shut off your sink. Replacing the cartridge or washer should fix the problem.

Building codes don’t allow homeowners or businesses to run sewer pipes and water lines in the same trench for safety and environmental purposes. If the sewer line started leaking, it would risk contaminating the water supply to your house, which threatens the health of you and your family. These lines need to be in separate trenches and may need to be separated both horizontally by around 5 to 10 or more feet and vertically by 12 to 18 or more inches.

Sometimes. While many traditional homes use copper, galvanized steel, PVC, acrylonitrile butadiene styrene (ABS), and PEX, mobile homes will typically use PVC, CPVC, or PEX. These materials are more flexible, easier to work with, and handle colder temperatures.

National emergency plumbers usually have greater availability to address emergencies because they have more professionals at their disposal, but local plumbers may be located closer to your home and can arrive faster. We recommend contacting one or two local plumbers first to see how quickly they can arrive. Move ahead with the service if it’s within a reasonable time frame. If not, contact a national company to see if they can get out more quickly. National companies sometimes outsource work to third parties, which can often mean faster response times.
