• Vent set:You will receive 4 black ABS structural in-line exhaust vent valves, which help prevent sewer gases from entering your home, keeping you and your family free from unpleasant odors.
• Working principle:The air vent valve features a spring-loaded design. As water and waste flow through the drainpipe, negative pressure is created within the pipe, causing the seal to lift and allow air to enter. When the negative pressure subsides, the seal automatically returns to its original position.
