"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."

"Victor responded after hours to replace 2 water pressure regulators. Had necessary equipment and completed job and checked main, ADU and house to inspect water inlets working. I would not hesitate to call for all plumbing work at both my houses. I have found a plumber I can respect and count on that charges reasonable fair prices. Will recommend him to family and friends.

"Unfortunately there was a defective fitting that caused a pipe to burst. The house was vacant so we didn't learn about it until the next day. Alvin bent over backwards to repaire the damage, replace the ruined water heater, and make us whole. He even changed the water heater to a tankless model because the location of the ruined water heater didn't meet code and tankless was our only option."

"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"

"We had a 50-gallon gas heater that started leaking, and we needed to get it replaced urgently. I submitted an online request, and they literally called me within 10 seconds! They arranged for a visit for an estimate within one hour. The on-site project manager was Jason V. He assessed the situation and gave us a very clear, on-the-spot estimate. After that, he went to the supplier to acquire the new water heater and other parts. They came back within an hour to start the job. Jason and his coworker Hulices took about 3 hours to complete the job. They were both extremely courteous, professional, and knowledgeable. We felt very comfortable having them at our home, and their work was outstanding. We were particularly impressed with how fast the project came together and that is was fully completed the same day. We also had guests arriving soon, and there were going to be 6 people in the house that weekend, so we couldn't risk having a damaged water heater. So, they really saved us!!"

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.
