Repiping Procedures

Purpose

Procedures for whole-house and partial repiping jobs.

Customer has approved a repiping estimate (galvanized to PEX/copper, polybutylene replacement, etc.)

Review the scope: which lines are being replaced, what material, what access method

Protect the entire home: drop cloths on all paths, furniture covers if needed

Shut off main water supply

Plan your route through the home — minimize wall cuts and ceiling penetrations

Install new lines: PEX is standard for most residential repipes. Follow manufacturer specs for fittings and support

Support lines properly: hangers at required intervals, no sagging

Pressure test the new system before connecting fixtures (minimum 60 PSI for 30 minutes)

Connect all fixtures and verify operation

Patch wall/ceiling openings or coordinate with a drywall contractor per the estimate

Final pressure test with fixtures connected

Flush the entire system to clear debris before the customer uses it

Document everything with photos

Use the correct PEX type (A, B, or F) per Spartan standards

Crimp or expansion fittings per system specification — do not mix systems

Protect PEX from UV exposure — no exposed runs near windows

Support PEX per code: hangers every 32 inches horizontal, every 10 feet vertical

Leave expansion loops for thermal movement

Repiping is a multi-day job for most homes — see Multi-Day Job Coordination
Customer communication is critical — explain the timeline, mess, and restoration plan upfront
Advantages of PEX: corrosion resistance, flexibility, faster installation, fewer fittings
Present Good/Better/Best: partial repipe vs. full repipe vs. full repipe with water treatment
