Product Details
✓1-1/2 Inch NPT ABS In Line Vent: This 1-1/2'' NPT ABS in line vent can replace any secondary plumbing vent which protecting the traps of lavatory sinks, bathroom basins, tubs, showers or washing machines; It helps prevent sewer gas from entering your home, no more suffering from the smelly sewer gas caused by garbage disposal
✓Durable ABS Construction: Made of durable and strong ABS material, it is durable and able to withstand stress without cracking, also has good resistance to various chemicals, including acids, alkalis, and oils, though it can be affected by strong liquid, which can use for a long time
✓How it Works: Air admittance valves are operated by gravity; When water and waste move down a drain line, it creates negative air pressure in the pipe; This negative pressure lifts the sealing washer and lets air in, which allows the waste to drain away freely; When the negative pressure ceases, the sealing washer falls back in place; Earlier versions of this device were spring operated; Such units are still available but are unreliable and don't meet code in most areas
✓Easy to Install: The sealing disc of the vent must be at least 6 inches above the top of the trap arm; To ensure that this requirement is met, you can extend the tube using a sliding joint; An angle installation of no more than 15 inches from the vertical direction is acceptable; After determining the placement, you can install the Air Admittance Valve on the PVC drain line
✓Warm Tips: The vents must be easily inspected or replaced; If mounted inside a wall, a simple access panel must be provided; Important note: This item is only applied as an auxiliary ventilation device; Every drainage system that uses vents must have a main vent to the atmosphere, which should be located to facilitate the ventilation of the toilet bowl
