The Hotun® range of dry trap tundishes allow you to run a PRV discharge to a waste pipe with ease.
The patented Hotun range of dry trap tundishes, allow a conspicuous, visible & safe means of discharge from a sealed system boiler or unvented water heater’s relief valve, to be compliantly connected to an internal waste or soil pipe without allowing foul odours or gasses back into the building.
VISIBLE & SAFE MEANS OF DISCHARGE FROM A SEALED SYSTEM BOILER
All Hotun products allow for easy identification of historical relief valve operation via its open-sided construction.

FOR SMALL UNVENTED WATER HEATERS
For small unvented water heaters (less than 15 litres capacity) the hotun dry trap tundish provides the perfect solution to compliantly resolve any PRV discharge issues. Being small and compact with 2 standard connections, hotun can be installed in a matter of minutes and in the most confined places.
Connect the water heater’s pressure relief valve (PRV) through hotun and then direct to a local waste or foul drain, without odours being ventilating back into the building.
This provides an air break to drain with a safe and visible means of discharge, thereby allowing a compliant* connection.
FOR LARGE UNVENTED WATER HEATERS – HIFLO RANGE
For large unvented water heaters (greater than 15 litres capacity), hotun hiflo dry trap tundish provides the perfect solution with a simple, compliant, single product T/PRV discharge installation.
Connect the water heater’s temperature/pressure relief valve (T/PRV) through hotun hiflo and then direct to a local waste or foul drain, without allowing odours to ventilate back into the building.
This provides an air break to drain with a safe and visible means of discharge, thereby allowing a single product compliant* connection.
The flow capacity of the hiflo unit is 18L/min. If your system T&PRV has the possibility of discharging volumes greater than this under failure operation, the installer must assess on a job by job basis that he/she is happy that the installation will operate safely under a failure on failure basis.
HOTUN RANGE WITH SPEEDFIT TECHNOLOGY
The Hotun SF features a John Guest inlet connection which simplifies installation and allows for easier compliance with building and water regulations. The Hotun SF allows the T&P and Pressure relief valve to connect directly to the internal waste or soil pipe eliminating the need for external discharge. The non-return valve within the Hotun dry trap tundish stops any foul odours from entering up through the tundish and back into the building.
The entire Hotun Speedfit range is WRAS accredited.
