"Western Rooter to the rescue again! I had a small underground leak which appeared to be due to a bad sprinkler valve. A sprinkler repair company determined that it was not a bad sprinkler valve and thought it was due to a leak in the main water line. Daniel and Alex dug down to find that the leak was coming from a very old (at least 36 years) broken pvc line. After much testing and head scratching to try to figure out where the water was coming from, they decided to "chase the pipe." After much digging, they found that the very old broken pvc pipe was hooked up to a sprinkler valve that was buried 18 inches underground that had not been capped--only turned off. Roots from a nearby tree had opened the valve which caused the leak--crazy! The current sprinkler system has been the same one since we moved into the house in 1988. It took 36 years for the underground leak to occur!"

"Based purely on these reviews, GMC was the first and only company I called to install a recirculating tankless water heater. I found Geremi to be extremely reliable, and an excellent communicator via text or whatever. He told me in advance when he would arrive, which he confirmed often, he DID show up on time, the job site was clean and the installation was well done. I asked Geremi to come back to our house a few days later to make some minor adjustments to the system. He did so without hesitation and without any additional charges. I have nothing but positive comments for GMC plumbing."

"Javier scoped the main sewer line and accounted for each water outflow (kitchen, toilets, bathroom sinks, shower, bathtub and laundry). He showed me the line breakage and how the water was slowly seeping into the ground. I felt comfortable with him since he was so detailed and understood where to dig (instead of disrupting the whole yard/garden area). We were concerned about how dirty the job could be, but they tried to keep the movement of dirt to a minimum. As they finished the job each day, they cleaned up the area and getting it ready for the next days work. They only had to shut off the water/sewer usage for one day which made my 91 year old mom happy, We replaced and installed a new sewer system. The pipes to the kitchen, toilets, sinks, tub/shower and laundry were all replaced. They installed rebar dowels before cementing the floors. Upon completion of the whole project they put the yard/garden area back in order. Javier and crew did an outstanding job."

"My family recently moved Fresno. When we lived in LA we hired Johns Plumbing to install a new water heater. It was 40 gallon Bradford White water heater. John gave a free estimate first. Then his team installed water heater. Victor and his helper worked fast and accurate. We highly recomend Johns plumbing"

"Iâ ve worked with Alvin Ramirez, All Season Rooter and Plumbing on my sisterâ s home. My experience with Alvin has been truly outstanding. As she was in a care facility and I live 400 miles away, it was a challenge. It started out as a busted water pipe emergency. Subsequently, the house water, plumbing, gas and sewer/septic pipes have required replacement. I appreciated the personal care and assistance I received from Alvin with texts, pictures and phone calls. He performed in-depth analysis of the replacement costs for her home and made sure it was updated. The work was reasonably priced. With all the concerns of the situation, Iâ m grateful to have known that Alvin has been conscientious, honest and reliable. Heâ s truly gone above and beyond to be helpful in a very stressful situation."

Customers say: Quick response

"I stared to look for a plumber after I found water under my water heater. I jumped on Angi and posted my issue. With in minutes....Art messaged me and said he can be her 1st thing in the morning. BTW. This was 10pm at night. His quick response was a plus for me. I had one other respond but he over extended himself to my need. He came at 7amd and said....you need a new water heater. I can got get one and install it now. I was a bit reluctant and he said call me when your ready and left. My wife said his prices looked fair and he seemed like a good plumber. I called him back and said lets dance. He was back at my home in a hour and 1/2...and started the work. He protected my carpet and placed plastic on it. He warned my that maybe the cost might go up due to the age of the pipes and valves. He had the old one out and the new one in an an hour or so. He was quick, clean and polite. I paid him and shuck his hand. I recommend Art for your household plumbing needs. He was excellent."

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