The purpose of inspecting appliances connected to the drinking water network is to guarantee the quality of drinking water in your home or building, and to protect the public drinking water network.

During the inspection, the inspector checks whether the correct safety devices and non-return valves are correctly installed in the system. Connections to rainwater or other alternative water sources are also checked. It is essential that there is always a strict separation between tap water and non-potable water.

An inspection is mandatory in the following cases:
- new installation;
- in the event of significant changes to your installation (new bathroom, new rainwater tank);
- when recommissioning after closure;
- after identifying a breach or after carrying out remedial measures following a non-compliant inspection.
