Recoup Pipe HEX

The Recoup Pipe HEX is the latest evolution in WWHRS and successor to the UKs’ most-specified WWHRS product, the Recoup Pipe+ HE.

With the new Turbo Rotator helping to increase efficiency, achieving up to 68.5%. The new compact end design improves installation accuracy and durability. The Pipe HEX boasts a low price, incredible SAP points, easy installation, no end user interaction and a market leading 10 year warranty.

Along with the unrivalled benefits of its PVC outer, including cost reduction, on-site theft deterrent, and a reduced product weight; incredibly it offers an even better pound to points ratio in SAP than the Pipe+ HE.
