Has an automatic odour barrier instead of a water trap, so that it cannot dry out.
Can be removed for cleaning. VA-approved.
– SHOULD NOT BE USED IN MULTI-STOREY BUILDINGS
– Can react to the over- and under-pressure in the drainage system
– Correct venting of the drain system is therefore important, so that the odour barrier functions correctly
– Opens and closes with the help of a spring
– A rubber seal ensures that the odour barrier is closed when not in used
