A wet patch in the yard, dropping water pressure, or a water bill that won't quit usually points to a failing main line. Master Plumbing locates, repairs, and replaces water service lines across Twin Falls & the Magic Valley - with trenchless options that spare your yard.
Fast response - available 24/7
Your main water line runs from the meter to your home. When it cracks, corrodes, or gets root-invaded, the symptoms show up long before the pipe fully fails. Catch it early and save thousands.
Unexplained wet spots, puddles, or lush green patches over the line often mean water is escaping underground.
A sudden or gradual drop in pressure throughout the house can signal a leak or restriction in the main line.
Water usage climbing with no change in habits? You may be paying for water leaking into the ground.
Rusty, brown, or gritty water points to corroded galvanized or aging pipe that's due for replacement.
Where the line allows, we replace it with minimal digging - protecting your driveway, lawn, and landscaping.
From spot repairs to complete water service replacement in copper or PEX, built to last and code-compliant.

Older galvanized and poly lines corrode and weaken over decades of use.
Idaho soil and mineral content eat away at metal pipe from the outside in.
Roots seek out moisture and crack or crush buried water lines.
Hard Idaho winters can freeze and burst lines that sit too shallow.
Settling and ground movement put stress on joints until they fail.

"Our water bill doubled overnight. They found the underground leak fast and replaced the line with barely any digging. Impressed."
"Honest about what needed fixing - they repaired the section instead of upselling a full replacement. Fair and professional."
"Trenchless replacement saved my new driveway. Clean work, clear pricing, and my pressure is back to normal."
It depends on the age and condition of the line and where the damage is. We diagnose accurately first, then give you an honest recommendation - a targeted spot repair when that's all you need, or a full replacement when the line is at the end of its life.
