Plumbing Standard Operating Procedure

What a good one includes

• A pre-entry protocol detailing how technicians should greet customers, put on shoe covers, and lay down protective tarps before bringing tools inside.
• A standardized diagnostic checklist that includes shutting off the main water valve and checking water pressure before starting any repair.
• A truck stock and material logging procedure to track parts used and ensure the service van is restocked daily.
• Step-by-step installation and repair verification steps, including specific pressure or leak tests that must be witnessed and documented.
• A strict job-site restoration routine requiring technicians to wipe down fixtures, sweep the area, and remove all old parts and debris.
• A clear billing and sign-off procedure for presenting the invoice, collecting payment, and capturing a digital customer signature.

Common mistakes to avoid

• Making the procedures too complex and wordy, which leads to technicians ignoring the document entirely in the field.
• Forgetting to include photo documentation requirements, which leaves the business vulnerable to false damage claims from clients.
• Omitting clear safety protocols for high-risk tasks like using torches or working in confined crawlspaces.
• Failing to update the SOP when local plumbing codes change or when new invoicing software is adopted.
