Frequently Asked Questions
How much does it cost to replace a main water line?
Main water line replacement costs $3,500-$7,500 for a typical 50-75 foot run. Short runs (under 30 feet) cost $2,000-$3,500. Long runs or difficult access can reach $10,000-$15,000. Includes excavation, pipe, connection, and basic restoration.
How long does water line replacement take?
Main water line replacement takes 1-2 days. Excavation takes half a day, pipe installation 2-4 hours, and backfill/restoration the remainder. Complex projects with concrete or landscaping may take 2-3 days.
What are signs I need to replace my water line?
Signs include rusty water, low water pressure throughout the house, unexplained wet spots in the yard, higher water bills, and frequent leaks. Galvanized pipes over 50 years old and polybutylene pipes from 1978-1995 should be replaced.
What is the best material for water lines?
PEX (cross-linked polyethylene) is the most popular choice in 2026. It's flexible, freeze-resistant, and affordable ($0.50-1/LF). Copper lasts longer but costs 3-4x more. CPVC works but is less flexible than PEX.
