• Main trunk lines, branch lines, and fixture stops.
• Hose bibbs, laundry, refrigerator, dishwasher, and ice maker connections.
• New shutoff valves at fixtures.
• Pressure-reducing valve, expansion tank, or water heater code updates if needed.
• Removal or abandonment of old piping.
• Access openings, dust control, and protection of finished areas.
• Drywall, plaster, tile, paint, flooring, or cabinet repair.
• Permit, inspection, and water shutoff coordination.
• Final pressure test, flushing, and homeowner walkthrough.

Lead and water quality questions

• Has the service line material been identified from the curb stop to the home?
• Is there a local utility inventory or replacement program for lead service lines?
• Will any old galvanized pipe remain downstream of newer copper or PEX?
• Is water testing recommended before or after work?
• Will the system be flushed before normal use?
• Are filters, softeners, or treatment systems affected by the new layout?

Red flags to slow down

• The quote does not say which lines are included.
• Finished-wall repair is assumed but not written.
• The plumber will not discuss permits or inspection.
• Lead service line questions are ignored in an older home.
• The material warranty is presented without explaining labor coverage.
• The quote requires major access work but does not show where openings are likely.
