Details

Draining water can create negative pressure and suck dry kitchen sink water seals, leading to foul odors. This 1.5″ anti-vac kitchen sink trap adapter solves the issue. It adds an air admittance valve directly after the sink trap to equalize pressure, eliminate gurgling, and protect your water seal.

Instructions

1. Simply slide the white nut over the pipe first along with the nylon washer, before the pointed black rubber washer
2. Make sure that the black rubber washer is pointing the thin end towards the white fitting you have yet to put on and slide the rubber on an inch or so
3. Push the rest of the fitting on so that the rubber joins up with the plastic fitting, you may then try and push the fitting with the rubber further down the pipe if need be
4. Finally bring the nut back and screw onto the rest of the fitting, compressing the pointed washer against the plastic to make a seal, then repeat the action for the other side and that’s it!
