Invisible Water Leak: How to Detect and Repair Without Breaking Walls (Plumber Expertise)

It's the anxiety of every resident of an apartment in Paris: the damp stain that extends across the ceiling, the peeling paint, or worse, the neighbor downstairs ringing the doorbell ringing in anger. La Invisible Water Leak Is a devious enemy. It hides in walls, under wooden floors or in inaccessible technical columns.
The archaic reflex? Break the wall with a jackhammer to find the pierced pipe. Forget about that. Chez Network tubing, we use the latest technology for Non-Destructive Leak Search. Here's how we locate the invisible and how to manage this claim with your insurance.
Early Signs of a Built-In Leak
A leak can remain silent for weeks before causing visible damage. Here are the signs that should alert you immediately:
1. The Explosion of the Water Bill
If you receive a notification from your water supplier (Eau de Paris for example) indicating abnormal overconsumption, do not ignore it. A lightly leaking toilet flush can waste 600 liters per day. A leak under the slab, much more.
2. Boiler Pressure Drop
Do you have to put water back into your boiler every two days to maintain the pressure? This is an almost certain sign of a leak in the heating circuit, which is often embedded in the ground.
3. Visual and Olfactory Indices
- Molds in the corners of walls or baseboards that warp.
- Persistent Damp Earth or Musty Odor.
- Color change of tile joints.
How to Detect an Invisible Water Leak in Your Home
Our Leak Search Technologies (No Damage)
Our aim is to provide a surgical diagnosis. We only break if strictly necessary for repair, and only at the exact location of the leak.
The Thermal Camera (Infrared Thermography)
Ideal for hot water or heating leaks. The camera visualizes temperature differences in walls or floors. A hot water leak will appear as a red “spot” extending out of the straight line of the pipe. It's fast and completely non-invasive..
Video Inspection (Endoscopic Camera)
We slide a rotating head camera into your drain pipes (WC, shower, sinks). This allows you to see from the inside the breaks, the dislocations of connections or the intrusions of roots, which are frequent in old Parisian networks.
Insurance and IRSI Convention: Who pays for the Leak Search?
The administrative management of water damage is often more stressful than the leak itself. Since 2018, the IRSI Convention Simplifies things for claims under €5,000 excluding VAT.
Leak search is taken care of
