Greenwich Creekside

Greenwich Creekside

Greenwich Creekside UK Case Study


The Studor P.A.P.A. (Positive Air Pressure Attenuator), along with quality advice and speedy service, quickly solved the problem of unpleasant bathroom smells ‘back drafting’ into a prestigious fifteenth floor penthouse apartment in London, UK.


Greenwich Creekside, a superb flagship development of four multi-storey buildings designed by Thelford Homes, offers contemporary and sophisticated one, two and three bedroom apartments and penthouses close to the River Thames in South London.

Woodford Heating & Energy, who had been commissioned to install the heating and plumbing systems at Greenwich Creekside, was surprised to be called back because of sewage smells entering the penthouse apartment of block A. Woodford had followed the M&E designer’s specification and installed conventional Air Admittance Valves (AAVs) as directed. Block A was the only stack to have AAVs installed on the top floor; the other three blocks all vented into the atmosphere.

They quickly found that the smell was a result of the AAVs not being designed to work in such a high rise building, causing the traps to be sucked dry and resulting in back pressure with the inevitable sewage ‘return’.

Studor P.A.P.A. Solution

Roger Thomas, Contracts Director at Woodford Heating & Energy, looked for a solution on the internet and found the Studor P.A.P.A.: “I had not come across this problem before and was unaware of the Studor P.A.P.A., but I immediately realised that it would be the ideal solution”.


Roger further commented: “Since installing four P.A.P.A. units, in association with the AAVs, we have had no further incidents of bad smells being reported. I cannot fault Studor on efficiency, excellent customer service and speed of delivery. Our order was dispatched immediately and received the next day. We will certainly use Studor products again in the future, especially for high rise applications such as Creekside.”

The Studor P.A.P.A is a revolutionary ‘world-first’ system developed to resolve the problems of positive pressures within the drainage systems of multi-storey and high rise developments. The P.A.P.A. is the perfect complement to the range of Studor AAVs, providing a complete venting solution for any multi-storey building.
