hotun SF 

Product Overview

Now with 10 Year Warranty!

The hotun SF range of products, combines a tundish and dry-trap to provide a safe and visible discharge from a relief valve direct to a local waste or soil pipe, allowing a flow of water from the discharging T/PRV, whilst eliminating the risk of foul odours from the foul system entering back into the building AND providing regulation required, back-flow contamination & back-siphonage protection to prevent contamination of any wholesome water when connecting to the waste pipe (Category 5 risk water)

In a relief valve discharge application, due to the infrequent nature of the relief valve operating, a wet trap would dry out in time and thereafter allow foul odours back into the building, so is therefore not allowed to be used for PRV discharges.

The hotun 100C dry trap tundish was invented and patented back in 2014/15. It was the very first and original, dry trap tundish to be available specifically for boiler and unvented water heater installations as a one product solution and was the very first dry trap tundish to be accepted for use with many of Britains major and most respected boiler manufacturers, such as Worcester Bosch, Vaillant, Glowworm, Ideal, Baxi, Potterton, Ariston, Intergas etc.

The Speefit range of the hotun tundish now allows a quick and easy way to fit the tundish on the pipe using the well know and trusted John Guest brand of fittings. The collet insert allows for the tundish to be fitted to the D1 pipework in a matter of seconds
