Marley's dBlue Soil system hits all the right notes

Marley Plumbing and Drainage is pleased to announce that it has extended its popular dBlue soil range, which has been designed to reduce noise and acoustic vibrations to a level of 16dB at a 4 litres per second discharge rate, when using acoustic pipe brackets. The range includes soil pipes, sockets, brackets and backplates. 

As its name suggests, dBlue is uniquely blue in colour for easy identification on site, and has undergone rigorous acoustic testing by Fraunhofer, resulting in the range meeting the EN14366 noise measurement standard.  

The range includes 11 product including new backplates, brackets, an Akavent Aerator, an eight way collar boss to allow connections to other Marley systems, and a straight coupling. The Akavent Aerator, for example, is shaped uniquely to increase the capacity of the soil stack, allowing the soil and waste flow from the higher floors to smoothly converge with the flow on the lower floor. The entire range is particularly suited for multi-occupancy applications such as hospitals, hotels and apartment buildings where minimising noise is a necessity. 

Lloyd Winter, Head of Technical Services at Marley Plumbing & Drainage said: “At Marley we are dedicated to expanding and developing products that our customers want and need – and the dBlue range is no different. We have introduced two new brackets to the range: an acoustic bracket and a Phonoklip bracket. The Phonoklip is a patented acoustic body bracket, which has been designed to absorb noise generated by a building structure, giving it an acoustic rating of 16dB.” 

The dBlue acoustic soil pipe is constructed of three layers, which means that the propagation of noise generated by wastewater flowing inside the pipework is severely limited. The triple layered pipes also available in 110mm and 160mm and are lightweight, resulting in quick and easy installation – all while dramatically reducing the sound of wastewater.
