"Perfect! I called Western Rooter the AM my disposal went out. They were at the house the same day, at the time they stated they would arrive. The work was done efficiently and professionally and completed within an hour. I have called on Western Rooter for many years for various plumbing needs (clogged drains, replace water-heater, replace main water line, etc.) and have always had great, timely service at reasonable $$$."

"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."

"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

"We scheduled an appointment with Johns Plumbing to get an estimate for a couple of non-emmergency issues including water heater replacement and faucet installation. Price was fair and we decided to go with them. Plumbers were working fast, and they completed all the work within one day. I would recommend Johns Plumbing to everyone."

"Wes came out to look at a water heater issue my mom was having. He took the time to explain what the issue was, offered options, and ultimately replaced the water heater and some of the old piping around it that needed it. Never had a problem since. After that, we also hired Wes for other pipe replacement in the garage and in the laundry area. Again, haven’t had an issue since. He is a professional and I appreciate trusting that the job is done right and not being gauged for it. I would absolutely recommend Rapid Rescue Rooter & Plumbing."

"Project involved major repair of main sewer line, requiring installation of clean-out, jetting, and re-lining. Company seems very well equipped to tackle any size job. The 7 workers that were involved at various times all seemed to be well trained. Michael I, the lead plumber, is very intelligent, knowledgeable, and good to work with. Very nice people all around."

"I absolutely love that they work within your schedule to come out to perform services requested. I contacted their office late at night and they were able to schedule Chris the manager the next morning to provide me with a free second opinion. I had another local company that wanted to gouge me for everything that I had. This prompted me ti contact Renowned. After Chris did his free diagnosis, he went to me a reassured me that my issue was not as bad. I went ahead and had Chris and his team repair the section of sewer that only needed to be replaced. The entire sewer line did not need replacement like the other company stated it did.. Itâ s very hard to find trustworthy plumbers these days. Im so blessed I found mine."

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