Leak Location Visit Prep: A Checklist for Homeowners

What the plumber needs from you

Leak location depends on access and quiet. The plumber may need to reach the water heater, the house main, every fixture and the floor along the suspected pipe route, and acoustic equipment works best when nothing else in the house is making noise.

Information matters just as much. Your meter test results, symptom notes and any history of past leaks can shorten the search.

The day before

Move rugs, furniture and boxes away from warm or damp areas.
Clear space around the water heater and the house main.
Make sure the attic hatch is reachable if a reroute might be discussed.
Print your meter test log and symptom log.
Find records of past plumbing repairs, especially earlier slab leaks.
Locate your water bills for the last few months.

The morning of the visit

Avoid running water for an hour before arrival if possible.
Turn off irrigation timers, the dishwasher, washer and ice maker.
Plan to keep pets and children in a quiet room.
Switch off loud fans or a radio near the work area.
Have your questions written down.

What you will likely see

First minutes: Questions about your symptoms and meter results.
Early: Isolation of hot and cold sides and pressure testing.
Middle: Tracing the pipe route and marking it on the floor.
Later: Listening and scanning along the route for the leak point.
End: A marked location and a discussion of repair options.

Questions to have ready

What is your CSLB license number? I will check it at cslb.ca.gov.
Is leak location priced separately from repair?
Will I get the findings in writing?
Which repair options do you see, and why?
Can I keep using the unaffected side of the plumbing?

Common questions

Do I need to be home?

Usually, yes. The plumber will need access to valves and fixtures and will want to explain findings.

Should I turn the water off before the visit?

Only if the leak is heavy. Otherwise leave it on so the plumber can test the system as it normally runs.

Will furniture need to move?

Clearing the suspected area makes tracing and listening easier. Ask when booking if anything specific is needed.
