"The services we received from Oak Plumbing was FANTASTIC from the customer service (the ladies that answered the phones), to the Technicians. The quote/price for the repairs was very reasonable, as will as quick service. One of the things that I really appreciate was that both the technician that can to give the quote, and the technician that can to do the repairs both respected COVID Protocol including fresh booties for their shoes. Oak Plumbing will be my go-to plumbers for all my plumbing needs."

"Superior plumbing has saved the day for me on countless occasions. I hit a sewer pipe with a lawnmower because it was sticking out of the ground and hidden by overgrown grass. I didn't know what it was, and sewage started coming out a few days later. I had another plumbing company come out and quote me $30k for a sewer lateral. I then had Superior Plumbing come out since they had recently installed a sewer lateral for my parents' house for much less. They said a piece of the pipe fell into the pipe, causing it to clog. They pulled out the piece, then cut the pipe to the ground and put a concrete cap that said "sewer," so I wouldn't hit it with the lawn mower again. It cost $1700 instead of $30k! Last week, the landscapers hit the cast iron sewer pipe coming from the bathroom outside. I immediately called Superior Plumbing, and they came out in 30minutes, as luckily they were close by. They addressed the issue and returned a few days later to replace the pipe with PVS, which proved to be very affordable. I then had them return to strap pipes under the house and install a water pressure regulator, as the water pressure was 95 when it should be 60. This could cause major problems with too high water pressure down the road with burst or leaking pipes. Look no further than Superior Plumbing for your plumbing needs!"

"Freddy was very reponsive. Seemed knowledgeable. Worked with us to reduce costs for the repair of a broken sewer line. And got the job done. He also returned about a month later for a problem related to the original cause of the break, roots."

"3 men showed up, 2 seemed to be in training- Original bid was around $200. Lead plummer suggested I replace rather than repair which would cost around $300. When he was finished I was charged for both- the repair and the replacement. He also recommended replacing the valve inside the toilet. Since he changed this the toilet has been stopped up twice."

"Tyler was awesome and originally we thought we'd just need a faucet water hose to be looked at, but he discovered the real source of the issue and was able to fix that. He then discovered a few other things that had been/were leaking and took care of all of that in the time he was at the house. A very honest person, had high integrity, was polite and very professional. He was able to answer a lot of questions we had and made us feel confident in his abilities to get he job done right. I'd definitely hire again for any plumbing needs."

"The job finally got done, but it was a painful process. We called WDR around 9am and were told someone would be at our house between 12pm and 2pm to extract the water. Someone showed up at 2pm and did not have a large enough extractor to do the job. He called for another truck to come with a larger extractor. The 2nd truck showed up with two people in it shortly after 4pm and their extractor was also not large enough to do the job. They estimated that it would take them 5 hours to extract all of the water in our basement with their 100 gallon extractor. They sent the first truck to San Leandro to pick up a sump pump to pump the water out onto the street (fortunately, it was clean water). While the first truck driver was picking up the sump pump, the 2 men in the 2nd truck refused to continue to pump out the water with their truck until we signed their contracts. They provided us an estimate of $1140 when they had been at our house for almost 4 hours without having done very much work. We finally settled on an agreement just as the 1st driver showed up with the sump pump. An hour and a half later, the job was done and the final quote we were given was very fair, almost half of the original estimate. Toward the end of the job, the team was accommodating and worked to reduce cost by sending home everyone but the lead tech.
Having a flooded basement is traumatic and having a water extraction team that wasted so much of our time and energy was not at all helpful. Fortunately, everyone was nice and cordial and we worked out a satisfactory deal in the end, but unfortunately, I can't say that I would use this service again.

"Water heater was drained on Monday, but the workman did not have the proper equipment for the hose bib. As a result, a second workman had to come back the next day to replace the hose bib. It would have been better if the first workman came prepared to handle the entire job. Fortunately, my schedule was flexible so I was home the next day. It would have been a problem if I was not,
During the installation of the bib, it was discovered that the water shut off valve for my house was not working so I asked him to replace that for a separate fee, which, of course, increased the cost. Very happy overall with the work.

"The plumbers showed up on time, were very courteous and polite. They advised me of all the small problems that came up before just fixing it. After they left a plasterer came in and repaired all of the holes in the walls to change out the plumbing. I had minimal problems and would surely recommend this company.

FAQs for water main install, replace or repair projects in Knightsen, 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.
