Please Note:
This is a bare product and requires fittings to connect both the inlet and outlet to the pipework.
See related items below for information and to purchase if required.

The product is supplied, as standard, with a flat-faced rubber inlet washer which must be used and only hand tightened. DO NOT use a fibre washer.

hotun and hotun hiflo are patented, dry trap tundishes, that allow a safe and visible means of discharge from a sealed system boiler or unvented water heater’s Pressure Relief Valve to be connected to an internal waste or soil pipe without allowing foul odours back into the building.

hotun dry trap tundish allows trickle and a full flow discharge capacity of 12 litres per minute, temperature rated to 100°C. The perfect solution to allow running the pressure relief valve (PRV) outlet directly into a foul drain.

1/2? flat faced tap connector inlet (not supplied), 22mm compression outlet (nut and olive not supplied)

Comes with full installation, maintenance and warranty documents and typical diagrammatic installation option drawings
