"Jesus did a great job: the house builders installed irrigation that tapped into the water main before the valve into the house, so that a leak in the irrigation system (plastic pipes) meant that we had to shut off water to the house at the water meter at the curb. We had a leak in a buried plastic irrigation pipe, and so we had to do without water until it could be fixed. Jess installed a copper pipe to split off from the main pipe and added a valve, and mated copper pipe to the irrigation plastic pipes, so that if there were a future leak in the irrigation system, it's easy to shut that off w/o having to shut off the whole house. Jesus was on time, did a great job, fixed things quickly, and I'd definitely hire him again."

"Leo and Tony and Able are wonderful and amazing. They installed new shut off valves throughout the house and the main. New P-traps throughout, power washed all my decks and fixed two leaks on the second floor and repaired the ceiling. The most beautiful work was installing a new bathtub and tile surround. Able is an artist! Leo is so fair and honest and his team just works hard every minute they were at my house. Came when they said they would. Gave me updates. Did additional work that I asked them for. I would hire them again in a heartbeat. "

"**Highly recommend FDL Plumbing!** Francisco from FDL Plumbing was prompt, professional, and efficient. He arrived at 10am to diagnose my water heater issue and clearly explained my options. After discussing pricing, we agreed to proceed, and Francisco had a new unit installed by 11:45am, exceeding his initial timeframe. Francisco was a pleasure to work with â he completed the job expertly while maintaining a friendly demeanor. His work ethic and competitive pricing (especially for San Francisco) were refreshing. Thank you, Francisco, for the outstanding service!"

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