PUM - Purus Universal Membrane

PUM is a product range which offers you new possibilities. Patented technology which sets its own standard. PUM is also type-approved. The PUM works as a mechanical odour trap, using a silicone membrane instead of a water trap. The membrane is always closed, but is opened by the flow of water. The PUM also functions as an air admittance valve if there is negative pressure in the drainage system – it opens and lets air in when necessary.

Install a PUM to make life easier. No more blockages in drains, overflowing water, dried-out water traps or unwanted odours from drains. The PUM is easy to clean - you only have to rinse it under the tap - and it also makes space for other things in the bathroom cabinet. The choice is obvious, we think!
