Showers and WC’s are a potential risk to other areas within the building as there are usually a number of water services with high volumes of water running through them.

In most cases, a shower or WC will only need covering if they are above or adjacent to a room that is a high risk such as a data centre, comms room or server room.

However, it is also a possibility, that they will need covering purely because of the volumes of water and the potential damage that could be caused to the building due to a large leak.

The recommended method of leak detection is usually for a length of TT1000 to be installed in the floor void around the perimeter of the room. For areas such as this a single zone alarm panel is usually adequate as a leak can be spotted quickly, however if there are other areas that need covering a multi zone alarm or digital system (AT-MZA/ TTDM) would be more appropriate.

WC cisterns can be fitted with AT-350A overflow sensors to detect high water levels and monitored by local single or multi zone alarm panels.
