Best Installation Tankless Water Heaters in San Francisco CA

This is my first time ever leaving a review. I am so thankful for One Sources help at 4:30 am I had to share it. I woke to water coming from the kitchen upstairs through the lights in my downstairs bathroom. A pipe malfunctioned on the dishwasher and was flowing onto the kitchen floor and then flooding the kitchen. I frantically called 4 plumbers who said 24hr service but it turns out they just have an answering service and I was told someone would get back to me. No one did. The 5th company was One Source and he talked me through how to shut off the water which turns out to be pretty easy if you know where to look. I wasn't charged anything and it was just a very nice decent thing to do for someone at that ungodly hour in the morning. Thank you, Thank you!!

super nice and professional!

O’Grady was great. They came in, did a thorough job. The work has held up. Had to replace pipes under my sink & rather than mess w having my landlord do a slapdash job, I called them— got a reasonable quote and work is done. I’d recommend them.

Aside from being an ace plumber, John was courteous and professional in every way.

Great team over there from the dispatcher to the plumber, Kyle. They expediently got a replacement water heater installed when our in-laws were at our house. Kyle even came back to ensure that everything was secured to our liking.

The only con is that there's a premium price attached to the high quality service; we didn't have time to shop around though.

I'd still recommend them!

Polite and Professional. Arrived on time. Explained what needed to be done and did it. Shower fixed! Thanks Robert.

Chris was very helpful! He walked us through the whole process and everything was fixed super fast

After a no-show from another company in SF, I called 3 other places. Paul was friendly, courteous, and was efficient. He had a new water heater installed in this unit in less than 3 hours. Thank you Paul for making this so easy for me! I'll keep your number handy.

Incredible service! Very knowledgeable, and fairly priced. Only plumbing company I'll use from now on!

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!

Purchased a new washer and the valve was messed up from the old one. (I don't understand plumbing talk). Anyway, they came immediately and fixed it immediately. The household owner forgot to pay them directly, but they were kind and courteous and waited longer than they should have for their payment. Really nice company and people.

Next time, I'll pay them directly and the owner can reimburse me.

We need to replace our garbage disposal and checked Discount Plumbing. Was able to set up an appointment for the next day. Carlos came on time and worked on replacing the disposal as well as the pipes connections. Carlos is professional and helpful, he explained we need to run warm soapy water every so often to keep the grease from clogging disposal and pipes clear. Thank you Carlos.

Leak in the bathroom regarding toilet
Was told on phone plumber would arrive in 30minutes, he did arrive on time.on a Sunday morning.
Friendly, professional and repair completed promptly. Great experience
I would use them again. Thanks for your help Smelly Mel's.

Nick & team were reliable, friendly, super helpful, easy to communicate with and fixed our water heater! Really appreciated that Nick took the extra time to explain how the heater works, what was fixed and what to expect in the future. Highly recommend this business!

Mo is amazing! Came by quickly and repaired my dishwasher. He figured out what was wrong and fixed it in 10mins. Definitely gonna give him a call again.

Had a terrible experience of being over priced and told I had to pay $225 for an unsuccessful attempt at dislodging an object from the toilet. It was a five minute task that did not work. I said I’d pay for a house visit, but no way was i paying $225 for a “try at it” that yielded no results. He huffed off and told me that no one acts that way. It all felt disingenuous to me.
