"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"Angel and Clever Plumbing team are the best! They replaced water heaters, repaired leaks, clogged drains and various other plumbing jobs. I highly recommend Clever Plumbing for any plumbing issues! He has helped me with multiple plumbing jobs, both big and small, and has always been great to work with. He’s very responsive, quick to schedule, and does a great job figuring out practical solutions. He’s reliable, knowledgeable, and someone I know I can count on when something comes up. I wouldn’t hesitate to call him again or recommend him to others, you will not regret it!"

"Short version:
They got the job done, but it took two visits and cost about 2-3 times more than it should have because they initially arrived with the wrong equipment and then recommended an unnecessary, expensive video scan.  The extra cost was due to their error and they should have covered at least some of it (if not all) but they refused.

Details:

Our sewer line backed up between our house and the street, and so I called In and Out to clear it.  They arrived with nothing but a hand snake because supposedly other equipment was in the shop.  The plumber was able to (temporarily) clear the obstruction with the hand snake.  Charge: $250, which also included cleaning the trap in one of our interior sinks.  So far so good (although if I'd known they'd come with just a hand snake, I would have done it myself...)
Two weeks later, the line backs up again, because the hand snake only punched a small hole in the obstruction rather clear it completely.  I called In and Out to come back with the correct equipment.  

This time they arrived with the proper equipment, including the full sized snake and water jet to clear the roots.  Given the previous failure to remove the blockage, they recommended sending the video camera down the pipes to diagnose the problem.  Problem = roots from the trees near the sewer line (surprise!).  They used the snake + water jet to remove the roots and clear the obstruction.  Now everything works.  Bill = another $775.  

 Why do they get a C grade?
Issue 1: they refused to refund any of the money from their first, failed intervention.  If they'd just arrived with the right equipment, we would have removed the roots on day one, sparing us another sewer back up and another expensive visit.  They brought the wrong equipment and didn't solve the problem -- there should be at least a partial refund.  Even an apology would have been nice.  But I didn't get either.   instead, we come to Issue 2

 Issue 2:  when they came back, they recommended an unnecessary (and very expensive) video scan of our system which just turned up the obvious problem of roots from the nearby tree.
Total cost was over $1000, for a job where most plumbers would have just gone in with the big snake + jet on day one and knocked out the roots for $250-400.   In and Out ultimately fixed the problem, but we had to endure 2 days of sewer back up and paid 2-3x what we should have.

On the plus side, they were always very prompt, professional, and friendly in person (aside from issues noted above)"

"Got a note from SFPUC for massive water use for the past several days, but no clear smoking gun. Was really worried and called Francisco asking for immediate help. He was at my house in 15 minutes and walked through all the most common culprits (toilets, etc), until we heard the water running outside and found that my kids had left the hose running. Paid him for his time and will definitely be calling him the future - amazing service. Kids learned a good lesson too."

"Kenneth Asire Plumbing is the epitome of responsiveness, expertise, and great customer service. Our water heater failed and left my wife and me with no hot water. I used Home Advisor to get estimates, etc. Mr. Asire came out and gave us an estimate the next day. After obtaining two more estimates, we hired KAP, and we've never regretted it. Kenneth is extraordinarily knowledgeable, experienced, professional and courteous. The crew that he dispatched for the new water heater installation was great. The installation crew, Justin and Jerwin, were personable, clearly very experienced and did a marvelous job installing the new water heater and removing the old one. They worked very efficiently - from start to finish the job was completed in under two hours. We are very pleased with all aspects of our experience with Kenneth Asire Plumbing, would hire them again in a heartbeat, and recommend them very highly."

FAQs for water heater repair or service projects in San Francisco, CA

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
