Common Questions
Water Service Line FAQ
How much does water service line replacement cost?
Water service line replacement typically costs $3,800–$16,000+ depending on line length, depth, material, and regional factors. Copper costs more than poly pipe. Use the calculator for a quick estimate specific to your area.
What is trenchless water service line replacement?
Trenchless water service line replacement pulls a new pipe through an underground path with minimal digging. Only small entry and exit pits are needed, leaving your yard almost undisturbed, unlike traditional open-trench excavation.
How long does it take?
Most water service line replacements are completed in 1 day. The new water service line is fully operational the same day, with minimal excavation and yard disruption.
Is poly pipe or copper better for water service lines?
Both are excellent. Poly pipe (HDPE) is flexible, corrosion-resistant, and comes with a 25-year parts and labor warranty. Copper is traditional, premium, preferred by some HOAs, and backed by a 30-year warranty. Choose based on preference and budget.
Will trenchless work damage my yard?
Trenchless water service line work causes minimal disruption. Only small pits at entry and exit points are needed. Your landscape and hardscape remain mostly untouched, unlike traditional open-trench excavation that requires full yard restoration.
