Before you sign off
The last day of a repipe is the best time to ask questions, while the crew is still there and the details are fresh. Go room by room, run each fixture, and make sure you know where every new valve is.
Ask for the final inspection record if a permit was pulled, and keep it with your house documents.
Walk it in order
Main shutoff
Have the installer show you the main valve and close it once while you watch.
Every fixture
Run hot and cold at each sink, tub, shower and hose bib. Flush each toilet.
Appliances
Check the washer, dishwasher, refrigerator line and water heater connections for drips.
Attic and walls
Look at accessible runs for supports and protection where lines pass framing.
Patching
Walk every opening and compare it with what the estimate promised.
Documents to collect
- Final inspection sign-off or permit record.
- Written description of material and layout installed.
- Location of manifold or new valves, ideally marked on a sketch.
- Written terms on workmanship.
- Final invoice that matches the agreed scope.
Watch list for the first weeks
| What you might notice | Why | What to do |
|---|---|---|
| Air sputtering at faucets | Air left in new lines | Run fixtures briefly; call if it continues |
| Cloudy water that clears | Tiny air bubbles | Let it sit; it should clear from the bottom up |
| New stain on a patch | Possible slow drip | Shut off water nearby and call the contractor |
| Banging pipes | Loose support or pressure issue | Ask the contractor to check |
Common questions
Should I make final payment at the walkthrough?
Many owners pay after the walkthrough, inspection sign-off and patching are complete, per the contract.
What if I find a problem after a few weeks?
Shut off water if leaking and contact the contractor with photos and the date.
Do I need to flush the water heater?
Ask the installer whether any sediment was disturbed and what they recommend.
