SAVE WATER: AUTOMATIC WATER SHUT-OFF CONTROL
SAVE WATER + ENERGY: CONTROL BOTH THE WATER SUPPLY & LIGHTS etc.
EARN EXTRA BREEAM (Wat 4 Credits) BY INSTALLING THESE TO WASHROOMS

The Problem:
Faulty WC appliances or taps & showers (+ lights etc.) deliberately left on when a washroom is empty are not only an expensive waste of water and energy but also pose a possible risk of damage from flooding.

The Solution:
A PIR switch is used to control the water supply (+ lights etc.) into a room. When the PIR switch detects that the room is occupied, it will automatically turn the water supply (+ lights etc.) “ON” so that the appliances work as normal.
 
For PIR specifiction - please see details on our PIR switch lighting controls above.

Once the washroom has been unoccupied for a pre-set but adjustable time, the system will automatically turn the water supply (+ lights etc.) “OFF” again, thus saving water if the taps are prone to leak, or are deliberately left on. As such it is ideal in commercial buildings with public toilets (eg: Office Blocks, Hotel Rooms etc.) or where there is a risk of vandalism (eg: Municipal Public Toilets,Universities,Military Barracks etc.)

This system can also be used to control special indoor water features (eg: Fountains etc.) that you only want to operate when the room is occupied.

NB
It is strongly recommended that you fit an in-line strainer immediately prior to each valve to prevent gunge getting into the valve and causing it to fail.
