Most people describe a leak in words. A leak is a number, and you can measure it yourself in about fifteen minutes.
That matters because the rate of loss narrows the possibilities dramatically before anyone arrives. A meter dial that barely creeps and a meter dial that visibly spins are not the same problem, they're not caused by the same kind of failure, and they don't call for the same response. One is very likely a toilet or a weeping fitting. The other is a substantial break, probably buried, and it's costing you money by the hour.
Same symptom on the bill. Completely different job.
So before you book anyone, measure it. The method is below, it costs nothing, and it will make every quote you receive more accurate — including ours.
Flash Plumbing Co locates leaks across Aberdeen — measured first, then narrowed, then found without opening the building.
Tap to call, or take the measurement below first.
How to do it. Turn off every tap and appliance that uses water, and don't flush anything. Find your water meter. Most have a small leak indicator — a triangle, a star, or a low-flow dial — that moves with even a trickle. Note the position and the exact time, wait at least fifteen to thirty minutes without using any water, then read it again.
If nothing has moved at all, nothing is being lost on the pressurised side of your plumbing. That's genuinely useful information rather than a dead end — it means any damp you have is coming from a drain, from rainwater, or from condensation, and it stops anyone hunting for supply pipes in your walls.
Barely perceptible movement. The indicator creeps rather than turns. Most likely: a toilet flapper passing water, a dripping tap, a weeping fitting or valve, or a slow seep at a supply connection. What to do: dye-test your toilets first, then look at visible fittings. This band is where the free fixes live.
Slow but clearly continuous movement. The indicator turns steadily, and the reading changes noticeably over half an hour. Most likely: a persistent toilet leak, a small supply leak inside the structure, an irrigation valve seeping, or an early slab leak. What to do: isolate the irrigation and the water heater to halve the search, then book detection. This band is worth acting on now, because it's cheap to find and it won't stay this size.
Fast, obvious movement with everything off. The indicator turns visibly and continuously. Most likely: a slab leak, a service line break between the boundary and the building, a failed irrigation line, or a substantial leak inside the structure. What to do: shut off the main at the building — if the meter keeps moving, the leak is outside and it's the service line. Then call. This band costs real money every day it continues.
Movement so fast the dial is spinning. A major break. Shut off the water at the main immediately and call. There's no diagnostic value in leaving it running.
One caveat worth knowing: meters differ in what they measure and how sensitively they display it, so treat the bands as a way of sorting the problem rather than a precise measurement. What matters is the difference between nothing, barely, steadily, and fast — and that difference is obvious on any meter.
Those four steps take under an hour and between them they resolve or dramatically narrow the majority of unexplained losses.
If you're not sure which band you're in, call and describe what the meter did. That's a two-minute conversation, not a callout.
Isolation and pressure testing. The foundation of the search — confirming which section is losing water, and confirming which sections hold. It costs nothing but method and it does most of the narrowing.
Acoustic detection. Pressurised water escaping through a small opening makes a characteristic sound carried through pipe and structure. Amplified listening equipment locates it through slabs, walls, and floors. It needs pressure, which is why it's a supply-side tool.
Thermal imaging. Maps temperature differences at surfaces — excellent on hot-side leaks and on evaporative cooling where water has spread through materials. It shows the extent of wetting, not just the point.
Moisture meters. Confirm how far moisture has actually travelled, which is almost always further than the visible mark suggests.
Drain camera inspection. For waste-side leaks — cracks, offsets, and failed joints found directly.
Tracer gas. Where a line can be emptied and charged with a detectable gas that escapes through the failure and is picked up at the surface. Useful where acoustic methods struggle.
Dye testing. For shower pans, toilet seals, and fixtures, confirming where water leaves the intended path.
Which we use depends entirely on what the measurement and the isolation established. No single tool finds everything.
The two categories behind most fast meter readings with nothing visible indoors.
A slab leak is a supply line failing beneath or within a concrete slab. The tells: a warm patch on the floor, an unexplained bill, running water with everything off, and new cracking in flooring or slab. It doesn't stop — water under pressure erodes the material supporting the concrete, which is why delay reliably increases the eventual cost. Repair options include opening the slab at the failure point, rerouting the line above the slab, or lining in some cases — and which suits depends on location, pipe material, and how many failures there have been.
A service line leak is between the boundary and the building, buried and invisible. The meter test at the main valve identifies it in a minute — if the meter keeps turning with the building isolated, it's out there. Repair cost depends heavily on what's above it: open lawn is manageable, a driveway or a mature tree is not. Trenchless replacement is frequently available and worth pricing against excavation.
They're different jobs with different amounts of work in them, and neither can be priced accurately before the other is done.
A leak at an accessible fitting takes minutes to repair once located. A slab leak may take hours to locate and then be either straightforward or substantial.
So you'll get the search price before we start, and the repair price once we know what failed and where. Anyone quoting a single number to find and fix a leak nobody has located yet is either padding it heavily or planning to revise it.
The repair cost is generally stable. The damage cost isn't. That's the honest reason not to keep an eye on it.
We locate leaks for restaurants, retail, offices, warehouses, and multi-unit residential buildings across Aberdeen.
The meter is even more useful commercially, because consumption is usually monitored and an unexplained increase is noticed earlier — provided someone is reading it.
Larger systems make isolation more valuable, not less. Long runs, multiple risers, and undocumented modifications mean methodical elimination frequently does more work than any instrument.
In multi-unit residential, water travels between units and the affected unit is often not the source, which makes detection a coordination exercise as much as a technical one.
Irrigation and landscape systems account for a large share of unexplained commercial water use, and they're the first thing worth isolating on any site with grounds.
The variables, so you can see where a number comes from.
Detection is quoted before we search; repair is quoted before we fix. And the measurement you took before calling makes the first of those more accurate.
Flash Plumbing Co proudly serves Aberdeen, MS and the surrounding neighborhoods, locating and repairing leaks in residential and commercial properties throughout the area. Unsure whether you're in range? Call and ask.
Turn everything off, note your meter's leak indicator and the time, wait fifteen to thirty minutes without using water, and read it again. Any movement means water is being lost.
Usually a toilet flapper, a dripping tap, or a weeping fitting. Dye-test your toilets first — that alone explains a large share of small losses, and it's a cheap part.
Shut the main at the building. If it keeps turning, the leak is outside on the service line. If it stops, it's inside. Either way, call — that rate costs real money daily.
Yes, and it's useful. No movement means no pressurised leak, so the damp is coming from a drain, from rainwater, or from condensation. Those are three very different fixes.
Very possibly, especially if the increase is seasonal. Isolate the irrigation and repeat the meter check — it's the cheapest thing to rule out.
Shut the cold inlet to your water heater with the meter running. If the loss slows or stops, it's the hot side or the heater. A warm floor patch points the same way.
Locating it, usually yes — isolation, acoustic, thermal, and camera methods exist for exactly that. Repair may need access, but to a known point rather than an exploratory one.
A supply line failure beneath a concrete slab. A warm floor patch, an unexplained bill, running water sounds with everything off, and new cracking are the usual signs. It doesn't stop on its own.
Then it's probably not a plumbing leak. Timing tied to weather rather than water use points at roof, flashing, windows, grading, or foundation.
Because they're different jobs and neither can be priced accurately before the other is done. You'll know the search cost before we start and the repair cost once we know what failed.
Rarely. Water travels along joists and pipe runs before it drops, which is exactly why detection exists as a service.
More urgent than it feels, and the rate tells you how much. The repair cost stays roughly stable; the damage cost accumulates continuously.
Mostly driven by how far isolation gets us before equipment is needed, and by accessibility. You'll have the detection price before we begin.
