"My water heater was leaking and I needed it fixed asap because we had no hot water and I have small kids at home. Robert came, he saw the problem and fixed it fast and efficiently. He was professional and polite and the price was right. I will definitely call him again in the future. And have recommended him to family and friends. Thank you Drain Right Plumbing!!"

"Leo did a very extensive plumbing repair that required digging through my bathroom floor and replacing a huge pipe to the outside. He also prepared and installed piping and fixtures for a bathroom remodel. Always showed up when he said he would and had a great crew. Cleaned up as well. Would highly recommend. "

"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."

"They did a number of things. Braced and restrapped water heater and ran copper line for pressure relief to outside. Unclogged master toilet and reseated. Bolted down second toilet. Reconnected clothes dryer vent. Repaired air gap/garbage disposal and drain line under kitchen sink, crawled under house and remove galvanized pipe straps and replaced with nylon pipe clamps. I was a contractor and used to do this work, o an very critical. They did an outstanding job. Went the extra mile several times. I was expecting a bill for a higher amount but they stuck with their estimate. I recommend them highly and would use them again!!"

"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."

"Found that the dispenser was damaged inside.  Could not fix.  Had to come back the next morning to fix leaking under the sink due to the work on the dispenser.  Re routed the water line so that we would still have water to the refrigerator but the join leaked so I had to turn it off at the valve.  The rerouting meant that I could not push back the sliding shelf that holds the supplies.  Had to remove it to be able to close the cabinet door. <br />"

"Steve installed an earthquake gas shutoff valve. He carefully and thoughtfully considered the best way to make it fit in the limited space, and ultimately came up with a super-efficient solution that required a minimum of new piping. He explained and demonstrated how it worked, and how to turn it on and off. As he turned on the pilot light for the water heater after installation, he explained how to do it if I ever needed to do it myself. Quick to respond to my initial inquiry and further questions. Excellent service -- highly recommended!"

"My wife and I bought a house a couple years ago, and became owners of a radiant heating systems installed more than 20 years ago. Tony and Damian did a great job of understanding how my radiant heating system works, what repairs were needed/what was failing, and where upgrades were needed. They replaced the pump, both expansion tanks, and the neutralizer. Additionally, they noticed the hot water tank was installed incorrectly, and the hot and cold water connections were flipped. It's amazing the system worked, and it's nice to have a system that's correctly installed (even if it's 20 years later!). Additionally, they secured the expansion tanks to the wall (now required by code), replaced the deteriorating copper pipes connected to the neutralizer with plastic (I'm sure this is code now as well), and re-routed the overflow pipes to the outside (rather than the floor!). You can't go wrong with these guys, well done, they're true craftsmen to the trade."

FAQs for water main install, replace or repair projects in San Francisco, CA

If you notice puddles or standing water in your yard, a sudden drop in water pressure, cracks forming in your foundation, frequent clogs in your plumbing fixtures, or water that looks or smells unusual, you might have a leak in your main water line. These signs mean it's time to call a professional to evaluate the issue and prevent further damage.

A professional water main inspection is a comprehensive evaluation performed by a licensed plumber who checks every section of your plumbing system. The inspection costs $165 and uses advanced diagnostic techniques to identify hidden leaks or wear. This service clarifies the exact condition of your water main, enabling precise repairs that prevent future damage and ensure the overall health of your plumbing system.

Protect your water main by scheduling a cleaning and inspection every two to five years. The average cost of a sewer line cleaning is $400. It’s also important to never dig in your yard without first calling the dig line (811) to ensure you don't accidentally hit the water or sewer lines. Watch for soil erosion, low water pressure, or wet spots in your yard, and take immediate action if you suspect a leak. Remember, the longer you leave it, the worse the problem gets and the more costly it is to fix.

When properly maintained, your water main is engineered to remain functional for 50 years or longer. A durable water service in excellent condition should consistently perform without major issues for half a century. In contrast, metal pipes exposed to acidic soil corrode faster, whereas modern plastic pipes resist corrosion and function for decades beyond metal alternatives. Regular maintenance and inspections are essential for confirming your system’s longevity.

No, homeowners insurance does not cover the cost to repair a water main. Insurers fund only sudden, unforeseen events like a burst pipe and exclude gradual issues or normal wear and tear. Damage resulting from leaks, such as mold remediation or property claims, is not covered. It is essential to contact your insurance provider immediately to confirm your policy’s details and any potential adjustments needed.
