First of all, what is Waless?
Waless is a self-sealing trap for air conditioning drain water.
A silicone membrane is normally closed to prevent the entry of odors and pests.
Only when it flows, the membrane opens with the weight of drain water.
Until now, Waless was exclusively used for vertical piping, but this time Waless, a use as both of vertical and horizontal piping, has been released.
(Product number: YWLD20-25-30)
As the umbrella valve opens 360° anywhere, it can be used as a vertical or horizontal piping.
Maintenance can be easily done without tools because the membrane can be removed integrally with the inspection cap.
