Mains Back up - AB air gap kit, suitable for fitting on existing tanks to ensure an air gap is available between the mains water and the maximum possible water level.

By seating the mains back up above the tank:

More of the available main tank capacity can be used
The mains top up device (e.g. RainAid, Solenoid) is easily accessible without entering the tank
The Air gap and overflow are visible/accessible
An overflow (spill weir) does not have to be cut into the main tank reducing the available tank volume and compromising the tank

Simply install the mains water inlet above the rectangular spillover slot.

The kit is supplied blank and so inlet, outlet, electrical connections for solenoid valves, tundish etc. must be drilled.

Features

Suitable for flows up to 32 l/m (maximum design inlet flow)
Designed to WRAS regulations
Unit height 245x190mm
Headroom for inlet device ~110mm
Stainless Steel insect cover
Front face removable for access.

Included Accessories

40mm Tundish

Notes

Once installed checks will be needed to ensure the inlet device has no contact with any fluids within the receiving vessel. This must be verified when the device is operating at the maximum flow rate under normal operating conditions. If the receiving vessel can be subject to positive back pressure, it is important that the inlet device is positioned so that the ascending/returning backflow fluid cannot exceed the maximum design inlet flow.
