Product Description

Type AA Air Gap or Air Break.

Ideal for use as an air gap to prevent back-flow.

The 3P Tundish acts as a Type AA air gap to comply with BS8515 and BSEN13076 - "Devices to prevent pollution by back-flow of potable water". Properly fitted this Tundish prevents any possibility of contamination of the mains potable water supply with rainwater in accordance with the Water Fittings Regulations.

Install the Tundish so that the potable water can feed freely into the tank.
