Wallbarn EPDM SIPHON Roof Outlet (Perforated Flange) - H250mm - D100mm

WALLBARN PRESENTS A HIGHLY ENGINEERED ROOF OUTLET WITH A SPECIAL ANTI-SMELL SIPHON, TO CUT OFF ALL UNWANTED ODOURS FROM DRAINPIPES AND GUTTERS. THEY ARE A MASSIVE ADVANCE IN ROOF TECHNOLOGY TO TRADITIONAL CIRCULAR / DOWNPIPE OUTLETS

EPDM drain connector with anti-smell SIPHON.

Wallbarn has an ingenious product designed to improve the environment around drainage holes on roofs and podium decks. These products specifically target any unwanted smells, and are particularly useful on terraces or balconies, where greater pedestrian presence is anticipated, where the deck is used for dining, for example.
The SIPHON outlet is a variation on the design of the standard drain connector in EPDM which incorporates the perforated flange and spigot, but also contains 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 a small amount will be held in a well-type section, effectively sealing the drainpipe, in a similar way to a U bend beneath a sink unit. As the rainwater runs off the roof and into the outlet, the water level will rise over the internal lip and then flow into the drain pipe.

H is the height of the spigot or pipe

H1 is the height of the well – where the water will collect to block out the bad smells, and the excess flow into the pipe

D1 is the outer diameter of the flange or surrounding ring

D2 is the inner diameter of the pipe at the top

D3 is the inner diameter of the pipe at the bottom

D4 is the outer diameter of the well at the top and also the outer diameter of the leaf guard

D5 is the outer diameter pipe at the top
