WATERLESS TRAPS
The installers’ alternative to water traps AN INNOVATIVE WATERLESS TRAP, WAVIN HEPVO AVOIDS THE BUILD-OF WASTE MATERIAL, CAUSING BLOCKAGES AND SMELLS, ASSOCIATED WITH U-BENDS IN TRADITIONAL TRAPS…
Water traps have remained a key part of modern plumbing solutions since they were first invented centuries ago. But traditional water traps can lose their seal due to evaporation, siphonage, leaking or movement. Wavin HepVO is an innovative waterless trap which avoids these issues and is suitable for use on a range of sanitary appliances. The unique design of Wavin HepVO means there’s no U-bend in which waste material can potentially build up, causing blockages and smells. HepVO has been rigorously tested and is resistant to common household chemicals such as cleaners and detergents. Soaps, hair or food particles are less likely to cause a block with the HepVO valve. Wavin’s HepVO waterless traps were introduced 20 years ago as first-of-its- kind technology, developed with an elastomeric membrane which creates a seal between the sewer and the occupied space above. As water enters the silicone valve, the membrane opens until the flow stops. The outer pipe is a rigid structure which prevents any damage to the inside membrane. The membrane is so lightweight that only a very small amount of water is required to open it, meaning it can also be used in condensate drainage systems. With no need for a U-bend, the trap can be installed vertically or horizontally without impacting on the system’s ability to seal off discharge systems. As HepVO admits air into the drainage system, there’s no need to add a 40mm air admittance valve for branch ventilation to relieve negative pressures, which means an absence of the gurgling noises you get with a traditional water trap. HepVO will perform under back pressures which are 10 times greater than those experienced in a typical soil and waste system. It can also be used in temperature and pressure relief valves from unvented hot water storage systems. Additionally, if properties are left unoccupied for long periods of time, or drainage systems aren’t properly
HepVO is ideal for modern minimalist bathroom or kitchen designs.

maintained, the typical ‘U’ trap with a water seal can sometimes dry out and fail, meaning sewer gases can make their way back into living spaces. This is a common issue for holiday homes, motor homes or even boats. HepVO negates these concerns. As space in modern builds is at an absolute premium, HepVO also offers the benefit of being suitable to be used for a wide range of household plumbing applications, from showers to kitchen sinks, meaning homeowners can save space in multiple rooms across the home. HepVO is ideal for modern minimalist
bathroom or kitchen designs. Its smooth lines means that the valve has a very limited impact on the overall look of a space and can be left exposed without creating an eyesore. Declan Conlon, Wavin Sales Director, said, “HepVO allows installers to provide customers with both value-adding expertise and the best possible result. Given the multi-application nature of the product, it offers great versatility and negates the need to carry multiple traps to projects.” Contact Wavin for further information: www.wavin.ie
