The Hotun HW100C 15mm x 22mm Dry Trap Tundish is designed to provide a safe, visible and compliant discharge solution for pressure relief valves on small unvented hot water systems. Featuring an innovative dry trap design, it allows discharge water to connect directly into an internal waste or soil pipe without allowing unpleasant foul odours to escape back into the building.
Suitable for small unvented water heaters with a capacity of less than 15 litres, the Hotun HW100C offers greater flexibility when planning installations. Its design can eliminate the need for a separate external discharge pipe, helping avoid drilling through external walls and providing more options for appliance positioning.
The open-sided tundish design allows discharged water to remain visible, helping installers and property owners identify when a pressure relief valve has operated. With 15mm x 22mm compression connections, a flow capacity of up to 12 litres per minute and WRAS approval, it provides a practical solution for compatible installations.
