"My elderly mother needed a new water heater . I gave her the contact info for a great, honest plumber. But due to her dementia, she forgot and ended up having a neighbor call a plumber, they chose Albert Nahman . Two plumbers came out and spoke with her and my 85 year old uncle and they were convinced to hire them at a price of over $6k (which, if you can believe, included the "senior discount"). My mom and uncle are clearly confused and easy to take advantage of, and these guys went above and beyond to take advantage of them, charging 4 times what this job should have cost. I called and spoke to a manager and got a ridiculous story of how complicated this job was, and how they were charged a reasonable price. I took away that this company is corrupt from top to bottom. If you want to be taken advantage of, charged way more than any decent plumber would charge, and then treated like an idiot who doesn't know that they are being cheated, this is the company for you!"

"Rarely write reviews, but I had to take the time to recognize the incredible service I received from Green Arrow Plumbing. From start to finish, this was hands-down one of the best service experiences I’ve ever had! I originally called for a relatively simple job replacing a shower head but while they were here, I also mentioned a persistent issue with my main house drain being clogged. Without hesitation, they jumped into action and took care of both problems quickly, efficiently, and with zero mess left behind. They were punctual, professional, and friendly . They explained everything in simple terms, gave a fair and honest quote, and stuck to it. No upselling, no surprises just quality work done right the first time. If you need a reliable, honest, and highly skilled plumber I highly recommend Cornelio. I’ll definitely be calling them again for any future needs. Thank you for making what could have been a stressful situation completely stress free!"

"When I needed to get a water heater replaced before a weekend after calling it on a Wednesday afternoon, they did it. Every other plumber called could barely send someone to give a quote! It can be hard to find a service company in San Francisco that behaves like they want your business so I was truly grateful. And while the job cost a lot more than I expected, they were able to help with the price because I was in a tight spot financially. Also, when I had an issue that I discovered later on with hot water not getting to the hydronic central heating, Adam came back to bleed the line when I was out of town! That's excellent customer service right there! They have a great team and they run a tight ship!"

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.
