When a drain line is PVC, the IMC dictates that it should be supported every 4 when horizontal (while maintaining proper pitch) and every 10 vertically. The Sabik 500 has been designed to provide balanced and sustainable ventilation whilst incorporating modular features and user friendly controllability resulting in a high efficiency, market leading ventilation system. Solutions often proposed are for a trap of sufficient depth that water in the trap will not evaporate sufficiently to lose the trap seal during periods when no condensate is being produced. Thanks so much for watching and well see you on the next blog!
