Best Backflow Replacement in San Francisco CA

Available 24/7 for emergencies which is what I had on a Saturday evening. Showed up in less than an hour and repaired a leaking pipe underneath the kitchen sink. Super professional and the pricing is per job rather than by the hour. Would definitely use them again if I needed plumbing repair.

Grateful to find once source plumbing. Very professional, on time, accurately priced. Highly recommend.

We needed a plumber this morning which is a Sunday emergency call to snake my drain. Isaac showed up within the hour and was amazing. He fixed the problem and was very professional. I will highly recommend Isaac to my family, friends and neighbors for any of their plumbing and/or heating needs.

I have had a recurring issue with my toilet that had become a real embarrassment when I had guests over. Other companies have given me estimates to fix it / replace it, but it was just too pricey. When I finally called O'Grady plumbing they informed me it didn't have to cost me an arm and a leg. I was sold on a low flow toilet that will actually save me money in the long run. Plus the staff was very knowledgeable and courteous, which goes a long way with me

Jonathan and the team are spectacular!! The crew is friendly and professional. Just a world class team with expert technicians. Would definitely recommend.

Best birthday gift ever!
Clearing the sewer lateral clogged by tree root!

Perhaps the best plumbing company I've ever used, from the first phone call I made (at 7:30 am!), to the serviceman's on-time arrival and his rapid completion of the task. He even provided a mini-tutorial while under the sink showing his activities along the way to part replacement. We will certainly use Advanced whenever anything else becomes a problem. Alex Fernandez certainly deserves the 5.0-star rating he had even before we added ours.

I can't say enough about what a great job Angelo and his crew from Discount Plumbing did with our rental home in Oakland. Angelo called me right away to set up a next day estimate. He and his crew were on time and very thorough. originally, it look like it was going to a straight forward trenchless project and Angelos's quote came in well below several other bids.

Angelo and the crew got to work on time the next day and we were lucky enough to get the once in a blue moon plumbing disaster. A city tree had a root that grew into the line and ran over 52 feet to the house from street. Angelo called me right away and kept myself and my up-to-date with multiple messages as our simple trenchless project turned into a massive multiple trench sewer excavation. After seeing the extensive work that had to be performed it was an incredible relief when Angelo gave us the additional expense from the original quote which was incredibly reasonable. At this point we were at his mercy and I felt that he made sure that he didn't take advantage of the situation. In this day I think this type of honesty is hard to come by and it almost brought me to tears.

Angelo and his crew worked long hours for two days on our little sewer project and they we so professional. The kept the area as clean as possible and communicated clearly with my neighbors, my renter and myself. Angelo was so extremely helpful and positive even as the project got bigger and bigger.

We found Discount Plumbing through all of the fantastic BBB and we could be more pleased than with the support, They earned my highest recommendation and I mean earned it!

Nice guys and Very informative. Helped me understand what was my exact problem and the best options for solutions!

The plumber was prompt, even a bit early, and fixed my stopped up drain. I will definitely use them again.

Moe was top notch! Will definitely have him come back in the future

Great Job, thanks AB Plumbing Team :)
The price was affordable and the service very reliable.

Jason (owner) is a great person to work with. I called about 10 plumbing company’s on a Saturday and he was the first to call me back. He came over and helped me out right away. Jason is a true knowledgeable professional to work with. I had a complicated issue at my house and he was dedicated to seeing me through the end and making sure I always understood what was going with the plumbing. As a contractor myself I could not recommend him more to work with. His right hand man Frank has good plumbing jokes too!

The job is amazing,
