Restaurant and food-service leak detection
The line is under the kitchen slab, the kitchen cannot close, and the wet floor is never where the pipe is. Finding it before anything gets cut.
Why kitchens are the hard ones
A commercial kitchen is the most awkward slab in the Valley
Everything about the room works against a search. Quarry tile and thick housekeeping pads sit over the concrete. Equipment is bolted down. A hot-water recirculation line often runs under the slab, so the floor is warm in places for innocent reasons. Floor sinks and drains are everywhere, which makes a wet floor normal and stops it being evidence. And the room is occupied from prep to deep clean.
The water lies to you as well. The damp patch by the dish pit is usually the last place the water passes through, not where it left the pipe, so cutting at the wet spot is how a small locate becomes a large hole under a cook line.
Hot line or cold line changes the whole approach
A leaking hot-water recirculation line under a kitchen slab is one of the few leaks thermal imaging reads beautifully: a warm stripe across the floor that does not match where the piping should be. A cold line gives no heat signature at all, so it is acoustic listening instead. Which leg is losing is therefore the first test, not a detail — and many kitchens can hold one leg while the other keeps the room working.
Method
Working around service, not through it
The schedule of the room decides the order of the work, so we ask about the day's shape before we ask about the leak.
Learn the day before planning the test
Prep, open, the rush, close, deep clean: every kitchen has an hour quieter than the rest, and that hour is worth more here than any piece of equipment.
Do everything that does not need the water off
Meter reading, exterior and slab-edge listening, thermal across the floor, moisture readings at the perimeter, plus the patio irrigation and mister line — none of it interrupts service.
Isolate the kitchen from the rest of the building
Front of house, restrooms, patio and landscaping all come out of the picture at existing valves, which in a strip-center space also separates your bay from your neighbour's.
Test hot and cold separately
Two smaller tests fit a service day where one large one does not, and the result says immediately whether thermal or acoustic work carries the rest of the job.
Take the water-off test into the closed window
Pressure isolation belongs in the gap between close and prep, or on a dark day, agreed in advance so nobody is waiting on anybody.
Mark the tile, photograph it, then talk about cutting
Rerouting a line overhead or through a wall is often far less disruptive than opening a slab under a cook line, and that choice should be made deliberately.
On site
The patio is a real suspect
Phoenix restaurants run misting lines, irrigated planters and shade-structure plumbing the kitchen never thinks about. A mister line weeping at a fitting shows up as a consumption change that appears in May and disappears in October.
It is also the easiest thing on the property to test, so it is ruled out early.
Scope, said out loud
What is ours in a kitchen and what is not
A kitchen is the room where a reader assumes a plumber does everything, so it is worth being blunt. We are leak detection and leak repair: water under pressure.
Ours
- Hot and cold supply lines under the slab and in the walls
- The buried line from the meter to the building, including runs under a parking lot or a drive-through lane
- The service line and water main feeding the site
- Patio irrigation, planters and mister lines, and the repair once the leak has an address
Not ours
- Floor drains, floor sinks, drain cleaning and sewer lines
- Grease traps
- Gas lines to the range and fryers
- Water heaters, fixtures and equipment connections
- Backflow assemblies
If the water on your floor turns out to be a drain rather than a pressurised line we will tell you, and you can put the right trade on it.
Reporting upward
The operator is rarely the only reader
A restaurant leak nearly always has to be explained to somebody who has never stood in the kitchen: a brand, a landlord, an owner in another city, sometimes a carrier. So the locate is written to travel — what was isolated, what held, where the failure is, and photographs of the mark before anything was opened.
The landlord conversation in particular runs on one fact: whether the failed section is on your side of the demising wall and downstream of your shut-off, or the building's. We state that plainly and leave the lease reading to the people whose job it is.

Straight answers
What operators and franchisees ask
Can you find it without closing the kitchen?
Most of the search happens with the kitchen running: meter readings, thermal across the floor, listening at the slab edge and outside, and checking the patio. The pressure test needs a section isolated, and that fits the gap between close and prep, or a dark day.
There is water by the dish pit every night. Is that not just a drain?
Often it is, and that is a useful answer to get. Drains are not our work, but we can establish quickly whether the water is arriving under pressure or backing up.
Do we have to cut the slab?
Not to find it; locating happens on top of the floor, through the tile. For the repair, rerouting the run overhead or through a wall is frequently possible and far less disruptive than opening concrete under equipment.
Our landlord says the line is ours. How do we find out?
By where the failed section sits: which side of the demising wall, and whether it is upstream or downstream of your suite's shut-off valve. We put that in the locate in plain language so both sides read the same facts.
Send a photo of the floor and tell us your quiet hour
A picture of the wet tile or the meter, and the time of day the room is calmest, is enough for us to plan a visit that does not interrupt service.
