We are very proud to have had our Basin Waste with Purus Universal Membrane (PUM) technology selected for use in the Utopia Basin Collection. The PUM is a new revolutionary membrane which saves space without reducing the flow capacity, which can be particularly crucial in bathroom cabinets. It also functions as an air admittance valve when there is a negative pressure in the drainage system (secondary air ventilation), which gives much better flow in the drainage pipe. The new technique stops bad air coming up through the drainage system.
The PUM product video is available to view now on our Videos page; with more product details available here.
