AquaPIR Automatic Water Supply Shut-off

PIR Water Leak Detector

Automatic water supply shut-off

Designed to comply with BREEAM WAT04 automatic sanitary shut off requirements.  The Aqua-PIR uses a PIR sensor to detect the presence of people in a room, which when activated, switches a solenoid valve to open the water supply.

  • Designed to comply with BREEAM WAT04
  • Prevents loss of water through leaking cisterns and taps being left running
  • Valve sizes available in ½”, ¾”, 1”, 1¼”, 1½” other sizes available to order

The Aqua-PIR can prevent wastage of water and as a result can help prevent excessive consumption and damage caused by water leaks.  With the valves in a normally closed position, the water supply to a WC or washroom is switched off.  When the PIR detects that the room is occupied, the valve opens and water is allowed to flow normally.  On leaving the room, a pre-set length of time will elapse and the valve closes again.

The Aqua-PIR can also be connected into the lighting system to switch the lights on and off during room occupancy.

Detection Range: 5m at 2,2m ceiling height.
5m at 2,2m ceiling height. 5 seconds – 40 minutes
Connections (BSP): ½”, ¾”, 1”, 1¼”, 1½”
Supply Requirements: 230VAC
Operating Temperature: -10 to 80⁰C


PIR Sensor

Aqualeak offer two different PIR infrared sensors, a ceiling flush mount and a ceiling surface mount version.

The infrared sensors are available in 240VAC and 24VAC and can be set to operate at between 10 and 40 minutes. It is possible to have a number of PIR sensors connected in parallel and can handle currents up to 6 Amps, which when used with the Aqualeak solenoid valves can have up to 3 connected to one PIR.

Water Leak Detection Valve Range

Solenoid valves are available for controlling the water flow to either switch off the supply in the event of a leak, or switch it on when demanded.

Valves are available in sizes between ½” and 2” and have zero lift specification and do not require any pressure differential for them to operate.  Water Leak Detection Valve Range Details
