Common Water Line Repair Scenarios
Main Water Line Leak
A leaking main water line between the meter and your home can flood your yard and foundation. Soggy areas, low pressure, or a spinning meter with everything off are warning signs.
Water Line Replacement
Old galvanized or lead water lines should be replaced with copper or PEX. Essential for homes built before 1960 that still have original supply lines.
Low Water Pressure
Consistently low pressure throughout your home often points to a corroded, partially blocked, or undersized main water supply line.
Water Line Freeze Protection
Insulating and protecting water lines from freezing — critical in colder regions to prevent burst pipes and service interruption.
Frequently Asked Questions
How much does water line repair cost in Sunnyvale, CA?
Water line repair in Sunnyvale costs $500-$3,000 for spot repairs. Full main water line replacement runs $1,500-$5,000+ depending on length, depth, and landscaping impact. Trenchless methods can reduce yard damage at a modest premium.
Who is responsible for the water line in Sunnyvale?
In Sunnyvale and Santa Clara County, homeowners typically own and are responsible for the water line from the meter to the house. The municipality maintains the line from the street main to the meter. Check with your local water utility for exact boundaries.
How long does a water line last?
Copper water lines last 50-70 years. Galvanized steel lasts 20-50 years (and can leach rust). PEX lasts 40-50+ years. Lead pipes (pre-1950s homes) should be replaced regardless of condition. If your Sunnyvale home has the original water line and it's over 50 years old, schedule an inspection.
Can a water line be replaced without digging up my yard?
Yes — trenchless methods like pipe bursting or directional boring can replace water lines with minimal excavation. Not all situations qualify (sharp bends, very shallow lines, or rocky soil may require traditional excavation). Ask the pros below for a trenchless assessment.
