This Wallbarn 250mm x 80mm EPDM SIPHON roof outlet with a perforated flange provides a very tough and durable seal around outlet drainage holes. The material is suitable for bituminous and EPDM waterproofing membranes. This product is suitable for bonded installation using the sandwich technique.
This SIPHON variation of the standard Wallbarn EPDM drain connector incorporates a siphon mechanism to help eliminate bad smells and odours emitting from the drainpipe up to the roof or deck. As water drains off the roof it will fall into a well-type holding basin, effectively sealing the drainpipe. Only when a larger amount of water flows in will the water level rise above the internal lips and run down into the shaft and into the HDPE drainpipe. It works in a similar way to a U bend.
The EPDM material remains extremely flexible even at low temperatures, and will tolerate 120°C, so it is ideal for being applied in hot melt membranes. The material is UV stable, and resistant to ozone and other atmospheric chemicals. It can even tolerate movement in the structure without risk of splitting.
