Endoscopy: inspecting inaccessible spaces
An endoscope is a small camera on the end of a flexible probe. It goes in through an existing opening (access hatch, air vent, joint, fixing hole) or a small drilled hole, to see inside a suspended ceiling, a service duct, dry lining or under a bath, without taking anything apart.
How it works
The probe is guided into the cavity while the picture is shown on a screen. This lets us follow a pipe, spot a dripping joint, water trails or wet material, and photograph what we see for the report. When a small hole is needed, it is easily filled, nothing like removing a bath panel or a ceiling.
When we use it
- checking a hidden joint behind a bath panel or a concealed WC frame;
- inspecting a service duct in a block of flats;
- following the path of the water in a suspended ceiling or a cavity;
- visually confirming a leak located by another method.
Limits
An endoscope only sees what is inside a cavity: it is no use for a pipe embedded in a solid screed. Its reach is limited to a few metres from the entry point.
