hotun – it’s not just a tundish
In one simple fitting, the hotun dry trap tundish solves the problem of compliantly running a Pressure Relief Valve (PRV) discharge from a pressurized hot water cylinder temperature and pressure relief valve (T/PRV) or boiler pressure relief valve (PRV) to a local waste or soil pipe. Furthermore, it allows flow in one direction while also stopping foul smells and odours from escaping back into the building.
In addition, hotun is fully compliant with Water and Building Regulations
hotun detect – It makes hotun sense!
hotun detect is another RA Tech innovation. For the first time ever, you can now have a clip-on, battery-operated, in-tundish water detection and temperature sensing alarm system thereby automatically alerting the homeowner or building user to any water dripping from the PRV through the hotun dry trap tundish.
