Repair & Replacement Execution: the full procedure

Perform the approved work cleanly, with the right parts, in the standard sequence the shop expects.

• Applies to: Plumber or apprentice doing approved repair/install work.
• Frequency: Every repair or installation job.
• Scope: Covers staging, performing, and documenting the approved physical work. Does NOT cover code-compliant installation methods, gas work, or backflow assembly, which defer to a licensed plumber, the plumbing/gas code, and the business safety plan.

What you need

• Approved work order / quote
• Hand and power tools for the task
• Replacement parts and fittings
• Shop materials (solder, tape, sealant, etc.)
• Camera for progress photos
• Drop cloths / containment (see Site Protection SOP)

The procedure, step by step

1. Confirm scope and approval before starting — Re-read the approved work order and verify it matches what the customer agreed to. Do not expand scope without a new approval.
2. Stage parts, tools, and the work area — Lay out everything needed and protect the area before opening anything up. Reduce trips and mess.
3. Shut off water to the work zone — Isolate the line per the Water Shutoff SOP before disconnecting anything. Confirm the line is dead before cutting.
4. Perform the work to shop standard — Use the methods, parts, and fittings the shop specifies for that repair. Defer any code-governed, gas, or backflow assembly step to a licensed plumber.
5. Handle hidden conditions correctly — If you find a problem beyond the approved scope, stop and get a new written approval before proceeding. Never silently add or skip work.
6. Document the work in progress — Take progress and after photos showing the completed repair. Note part numbers and quantities used.
7. Restore water and check the immediate area — Slowly turn water back on per the shutoff SOP and watch for leaks at every joint you touched. Bleed air from lines as needed.
8. Prepare for testing — Hand off to the Testing & Verification SOP before declaring the job done. Do not skip the formal test.

Quality check before you finish

• Work matches the approved scope exactly
• Water isolated and confirmed dead before cutting
• Shop-standard parts and methods used
• Hidden-condition work re-approved in writing
• Code/gas/backflow steps handled by a licensed plumber
• After photos and parts used documented
• No leaks at any joint touched after restoring water

This is a free, source-anchored standard operating procedure (SOP) you can print and hand to staff. It documents the work sequence for a Plumbing business — not safety or regulatory rulings, which defer to the cited authorities, the applicable code, and your own health-and-safety plan.
