"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. "

"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."

"In and out plumbing is great!  Easy to make an appointment... called at 9pm and scheduled service for the following day.  Plumber Mike was on-time and polite.  After showing him our leaky shower faucet, he provided two quotes- one to replace parts, the second to upgrade the plumbing to today's standards (1955 house).  After a few minutes we opted for the former.  Unfortunately there was a bolt that seemed to be glued in and so the handle stems had to be cutt off (also explains why my husband couldn't unsrew it the evening before).  The replacement were of an old design therefore Mike warned us that it may be difficult to find at a store.  He spend 45 minutes looking for it that day and upon not finding it at open stores, returned at 9am sharp the following morning to pick up the broken part (which he had replaced the night before so that the water could be turned back on for us) and spent about 60 minutes away while at another store.  Luckily he was able to find the part and had the faucet fixed by 11am.  During the entire work Mike was kind, communicative and obviously working hard to successfully complete the job. <br /> <br /> Additionally, another plumber, Steve from In and Out Plumbing provided service just a few days prior for another problem... a corroded pipe with a hole was leaking water from our kitchen drain.  Steve was also very polite, communicative about our options for the repair, and was able to replace 2 feet of piping in about 30 minutes.  <br /> <br /> In and Out Plumbing has been great on two occasions!  We will definitely use them again if we have any more plumbing issues."

"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.
