Whole-house repipes are the kind of plumbing project nobody plans for. Most Salt Lake area homeowners learn the term after their second slab leak or pinhole copper failure, when the plumber finally says the magic words: it is time to repipe. The decision is real, the cost is significant, and getting the right answer the first time saves you tens of thousands of dollars over the life of the house.
What makes a repipe necessary
Three signs that should put repipe on the table: multiple leaks on the same vintage of pipe within a short window, visible corrosion or pinhole leaks on accessible copper, or persistent low water pressure that pressure-boosting cannot fix. Utah hard water accelerates copper failure — older homes along the Wasatch Front frequently see pinhole leaks starting around year 25.
Galvanized steel is overdue
If you have galvanized steel supply lines (anything pre-1960), repipe was already overdue. Galvanized rusts from the inside, restricts flow, and contaminates water. The EPA drinking water guidance notes that corroding metallic pipes are a recognized source of contamination.
Copper vs PEX in Utah
The two real choices for a modern repipe: Type L copper or PEX-A tubing. Copper is proven and code-compliant. Downside: about 50% more than PEX, and Utah hard water continues to corrode copper over a 40-year horizon. PEX-A is flexible, faster to install, less expensive, and immune to most corrosion modes. Most reputable plumbers recommend PEX-A for whole-house repipes today.
What the work involves
A whole-house repipe runs new supply lines from the meter to every fixture. Stages: planning (1 week), permits (1-2 weeks), demo and access cuts (1-2 days), new pipe installation (2-4 days), pressure testing and inspection (1 day), drywall patching (2-3 days), paint (1 day). Most repipes complete in 5-7 working days inside the house. You can usually stay during the work.
Cost ranges
For a 2,000 square foot single-story slab-on-grade Utah home, expect $8,000-15,000 for a PEX repipe with drywall patching. Two-story homes run 30-50% more. Custom or large homes can run $25,000-40,000+.
Multi-state plumbing coordination
For property owners with multiple homes or investment properties across markets, regional plumbing providers handle each market. For related needs, we recommend residential and commercial plumbing services in the DFW region.
Permits and inspections
Whole-house repipes require permits in every Utah jurisdiction. Two inspections: rough-in (after pipe is run, before drywall closes) and final (after fixtures are reconnected and pressure tested). Permits add $300-800. Skipping permits jeopardizes resale and homeowner insurance.
