The best moment to look for the main stopcock or the consumer unit is not when water is already running across the floor. When moving into a home, it is worth locating a few basic items and knowing what belongs to the home, what is part of a common installation, and who to contact if the problem goes beyond the unit.
Why do this survey as soon as you move in?
Because a small failure becomes simpler when the occupant knows their home.
Knowing where the stopcock or the consumer unit is makes it possible to react without searching a service duct under stress.
This is not an invitation to work on technical equipment. It is precisely a way of avoiding improvisation.
Where can the water inlet be?
Depending on the building, inside the home, in a duct or in a service space.
There may be several valves, and not all of them are meant for the occupant.
The relevant device therefore has to be identified when moving in, with the owner, the manager or the documentation available.
What should you know about the consumer unit?
At the very least where it is, and the main device serving the home.
If a circuit trips, the occupant needs to be able to tell a simple reset provided for by the installation from a situation that calls for an electrician.
A wet area, a smell of burning or damaged equipment are not invitations to "try once more".
Which information is particularly useful to a tenant?
A move-in sheet can set out the accessible shut-off points, the building contacts, the rules specific to the common parts and the reporting procedure.
For a home let or made available, the 2019 regulations on sanitation, hygiene, safety and habitability also set criteria the landlord has to meet.
That does not remove the need for practical information: knowing where to shut the water off is still more useful on a Sunday evening than a regulatory reference.
Why not touch the common installations?
Because equipment that is visible or reachable is not always at the occupant's disposal.
The co-ownership law provides that the use of the common parts must not affect the rights of the other co-owners or the purpose of the building, while the syndic is responsible for keeping and maintaining the common parts. (loi du 16 mai 1975, art. 2 et 21)
How can this be passed on without overloading a tenant's arrival?
A few items are enough.
They can be handed over with the keys, placed in a digital folder or triggered automatically when a new occupant is registered.
The aim is not to produce a thirty-page manual, but to answer four or five questions before they become urgent.
