RWC TUND6000005 Dry Trap Tundish 15x22mm

Reliance Valves Dry Trap Tundish is a type AA backflow prevention device, meaning it is an unrestricted air gap. It is designed to take any discharge that may occur from either a Pressure Relief Valve or a Pressure & Temperature Relief Valve fitted to an unvented hot water cylinder. Water flowing through a tundish is an indication of a fault with the system and alerts the occupants of the issue.

It is typical practice to fit both a trap, to prevent odours coming up through the drainage system, and a tundish to prevent backflow into the potable water system. The Reliance Valves Dry Trap Tundish type incorporates a waste trap, saving time and cost when installing a discharge pipe into a soil or waste pipe. The specially designed seal prevents odours or gases from entering the building, while still allowing discharged water to be conveyed to waste safely.
