Vent cowl 75mm for soil / vent / waste pipe
The vent plays an important role in the sanitary installation and should be used to terminate every riser pipe after it has been routed above the roof.
The vent prevents negative pressure and water being sucked out of the traps of sanitary appliances,
as well as sewage digestion gases entering the premises.
It allows air to flow freely while preventing rainwater from entering the installation.
