Pre-purchase slab leak inspection: what to know in Arizona
Standard inspections do not look under the slab. A leak may not show until after you move in.
A check tests the lines and listens for signs in the time available.

Calls are answered around the clock, and same-day visits are the aim.

Arizona homes are slab-built and many have decades-old copper. The age of the plumbing and any previous repairs are worth knowing before purchase.
The inspection period is the time to ask.
What to do about a pre-purchase slab leak check
Ask the seller about plumbing history, repairs and any repipe. Request a meter check with the house quiet. Arrange access with your agent.
A technician can test the lines and report what was found.
What a leak detection technician does
If a leak is found, you can negotiate with the seller using the findings. If none is found, you know the lines were tested at that time.
A test is a snapshot, not a guarantee.
Nothing is opened until the leak is marked and you have heard the options.
Warm Tile Underfoot? Call NowQuestions to ask before closing
Ask the seller whether there have been leaks, what was done and who did it. A record of earlier repairs is useful.
A meter test with everything off is a quick check. Warm floor spots and signs of damp are worth noting.
Detection can be booked as part of an inspection period. It tests the lines and tells you what it found.
It does not give a view on the value of the house or on any claim.
What a pre-purchase leak check can show
A pre-purchase check looks for signs that water is leaving the system now. With everything off, the technician reads the meter and watches the leak indicator. If it moves, the lines are isolated and tested to find which one is losing water. If it does not move, that is a reading on the day, not a promise about the future.
The technician can also look for the usual surface signs: warm spots, damp baseboards, lifting tile and grout that stays dark. None of these proves a slab leak on its own, but together with the meter they build a picture of the house on the day of the visit.
The check does not tell you how long the lines will last or what material they are made of. Pipe material is confirmed only where a line is exposed, and the condition of a buried line cannot be read from the surface.
What you get is a description of what was tested and what was found, in plain language. You decide what to do with it, together with whoever is advising you on the purchase.
Arranging access and timing
The house you are buying belongs to someone else until closing. Access for any check goes through the seller or their agent, and the owner decides whether water can be shut off and lines tested. Ask your own agent how access is arranged for this kind of visit.
Allow time. Locating takes longer if the meter moves and lines need to be isolated one by one. If a leak is found, the seller may want to bring in their own crew. A check booked early in the process leaves room for those conversations.
An empty house can be easier to test than an occupied one, because nothing else is using water. If the home is vacant, mention it when you call. If it is occupied, the seller should know that water will be off to parts of the house during testing.
Pools and irrigation systems complicate a quick check. If the house has either, the technician separates them from the house lines first, just as they would for an owner. That step is part of the visit, not an extra.
After the check
If the meter stayed still and the lines held pressure, you have a reading from that day. Keep the written findings with your other purchase papers. If you move in and later notice a sign, the earlier reading is a useful comparison.
If a leak was found, the technician marks where it is and explains the repair options, just as they would for an owner. Who arranges and pays for a repair is a matter between you and the seller, and we do not advise on that.
If the results are unclear, for example a slow movement on the meter that could be a fixture or an outdoor line, the technician says so. A second visit after the seller has checked toilets, hose bibs and irrigation can settle it.
Once you own the home, the same first checks apply as for any homeowner: the meter with everything off, the irrigation controller off, and the pool level if there is a pool. Knowing where the main shutoff is on day one is also worth the few minutes it takes.
What to bring to the visit
Bring any information the seller has shared about the plumbing: earlier leaks, repairs, reroutes or repipes. It helps the technician know what to look for.
Ask whether the home has a pool, irrigation or outbuildings. Each adds a line to check.
Ask whether the water is on and whether the house is occupied. Both affect how testing is planned.
Bring a notebook or use your phone to note what the technician finds as they go.
Ask for the findings in writing.
If the check finds nothing
A still meter and lines that hold pressure are a good reading on the day. They do not promise anything about the future.
Keep the written findings with your purchase papers.
Once you move in, do the meter check every few months.
Know where the main shutoff is from day one.
If a sign appears later, the earlier reading is a useful comparison.
Reading the findings
The written findings from a pre-purchase check describe what was tested and what was found. Read them carefully and ask about anything that is unclear.
A still meter means no water was leaving at the time. It does not describe the lines themselves.
A moving meter means water was leaving somewhere. The findings say where testing pointed.
If a leak was located, the findings say where and what the options are.
Share the findings with whoever is advising you on the purchase.
Common questions from buyers
Buyers often ask whether a check can tell them the age or material of the lines. It cannot, except where a line is exposed. The year built gives a hint, but remodels and earlier repairs change the picture.
They ask whether an earlier repair is a warning sign. Not necessarily. One repaired leak on a line that otherwise tests well is common. Several leaks on the same run say more, and the seller may have records.
They ask whether a still meter means there is no risk. It means no water was leaving on the day. That is useful, but it is a reading, not a forecast.
And they ask what to do if a leak is found. The technician marks it and explains the options. What happens next, and who arranges it, is between buyer and seller and outside what we advise on.
Have the meter result ready: what the dial did with everything off, and again with the irrigation off.
Another Pinhole? Call NowQuestions about a pre-purchase slab leak check
Can you test an empty house?
Yes, with the water on. The house must have water running to the fixtures for the test to be meaningful.
How long does an Arizona slab leak job take (slab leak check before buying)?
A few hours. The technician explains what was found before leaving.
Do you provide a report for an Arizona job?
Ask the technician what documentation is available for an Arizona job. If a report matters for the purchase, say so when you book.
What if the seller refuses?
That is a decision for you and your agent. We can only test what we are given access to.
Can detection be done before I buy?
Yes, with the owner's agreement. Tell us when you call so access can be arranged.
Does it find every issue?
No. It reports what was tested.
Should I ask about earlier repairs?
Yes. Earlier repairs tell the technician where to look.
Do you advise on the sale?
No. The technician locates leaks and explains what is found, and the decision about the sale stays with you and your advisers.
