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