SIX7 PLUMBING
SIX7 Plumbing Leak Detection Colombo
Water travels — the stain is rarely the source. We cross-check meter isolation, thermal and acoustic traces and mark the point before anything gets broken. And we'll tell you plainly when tracing won't work.
The trace starts at the meter: isolate the house, watch the dial, confirm the loss is internal. Then thermal sweep and acoustic trace, two readings that cross-check each other, and a mark in centimetres. That mark is the difference between one broken tile and ten.
Honesty clause, because this is Colombo in summer: a slow drip inside a hot wall soaks the patch until the whole area reads cold and wet, and thermal cameras stop being useful; a drip that small is often inaudible to acoustic gear too. When the physics says no, we say no — and quote a targeted open-and-find instead of selling you a scan that can't resolve it. Detection here is skilled best-effort, not a magic wand, and we price it that way.
Not every loss is a leak. In Dehiwala's Hill Street area we've documented tapped neighbour lines — hidden connections where neither occupant knew water was being drawn off. Meter isolation separates a broken pipe from a stolen supply, in writing, before any quote. If the loss sits on the board's side of the meter, we say so and stop.

How We Find It
Our proven detection process finds the leak without unnecessary demolition.
Meter Isolation Test
We isolate your meter to confirm a leak exists and determine which side it's on — before we touch any tiles.
Thermal & Acoustic Trace
We sweep with thermal imaging and acoustic sensors to map the water path and find the exact source — no guessing.
Marked Point & Quote
We mark the point within centimetres and provide a written repair quote — so you know exactly what needs fixing.
Neighbor Approved
How we work on every call: findings written down, the point marked within centimetres, and a written quote before any repair starts.
"We mark the exact point before anything is broken — you approve the opening, not a guess."

One instrument can be wrong; two must agree — thermal and acoustic traces point at the same spot before anything is opened.

Built to Last
We use trace-grade thermal and acoustic equipment to pinpoint leaks with centimetre precision.
Thermal Imaging
Detects temperature differences from hidden water — no demolition required.
Acoustic Sensors
Listens for the sound of water escaping — precise enough to hear through concrete.
Meter Testing
Confirms the leak exists and which side of the meter it's on — before any work begins.
The Nitty Gritty
Hidden leaks live under slabs and inside walls. Guessing their position means breaking the wrong floor twice. Here's what we do:
- Meter Isolation Test: Confirm the leak exists and determine which side of the meter it's on.
- Thermal + Acoustic Trace: Map the water path using temperature and sound — no guessing.
- Marked Point + Photo: We mark within centimetres — one tile, not ten.
- Written Repair Quote: You know exactly what needs fixing before any demolition begins.

"The leak is where the stain is."
Water follows slab falls and pipe trenches; the source can be metres away.
Bill spikes usually appear 2–3 weeks before the first visible damp — that window is the cheap fix window.
Take a photo of your water meter reading before bed and again in the morning. If it moved while you slept, you have a leak.
