Altecnic Straight Black Plastic Tundish 22mm x 28mm

The use of a tundish meets the requirements of water regulations G19.1,
G19.3 and G19.4 contained in the “The Water Supply (Water Fittings)
Regulations 1999” and the “Water Byelaws 2000 (Scotland)” for sealed
or unvented systems.
The discharge pipe from expansion valves, temperature relief valves and
combined temperature and pressure relief valves should pass through a tundish with an AUK3 air gap.
The tundish must be located within the same room, as near as possible to the relief valve, since it is important that the discharge is clearly seen to warn of a possible problem within the system..
All Altecnic tundishes provide a type AA air gap since they all provide a minimum air break of 20mm.
A device with a type AA air gap provides additional protection above a AUK3 air gap and is suitable to protect against category 5 Back Pressure and category 5 Back Siphonage.
All Altecnic tundishes are WRAS approved products.
