HOTUN Dry Trap Tundish With Nut & Olive 15x22mm
The revolutionary, plumber-designed hotun dry trap tundish allows a compliant connection from any sealed system temperature and pressure relief valve to an internal waste or soil pipe. Allowing both trickle and full flow but preventing foul odours and gases from coming back into a property, hotun eliminates the need for an external discharge.
Due to its innovative and patented “air-break to drain” design, (the ultimate back-flow & back-siphonage protection), hotun can be cleaned and serviced (if required) in situ. There is no need to remove or dismantle from the pipeline which makes it ideal for use in hard water areas.
The 100C dry trap tundish has an open-sided construction and valve arrangement that allows water to be easily seen in the tundish, even after the temperature and pressure relief valve has stopped dripping. This means that diagnoses of any faults is quick and simple. 
As well as cost effective, hotun is a one-product solution and accepted for use by many leading water heater and boiler manufacturers.
