You may use the piece that you cut off from a drain pipe to place it in the top of a tee. It will depend on the kind of the air admittance valve that you have. You may be capable of gluing it straight to that pipe or to that piece. You will be in need of installing the threaded adaptor and you have to screw in a valve. Be sure that the valve had lots of air that surrounds it to make it function properly.
To have the finish up or the final output, gently wipe away those PVC cements that had oozed outside of your pipe fittings and just allowed the cement to dry out.
The installation of the island sink may be a bit defying, but the capability to use the air admittance valve will make it more likely for the savvy homeowner in dealing without the help or the support of the expert plumbers. But, when you have to install that more conventional vent or you deal with any problems, you may choose to call the help or the assistance of the professionals.
Here are the instructions that you can follow when you install an AAV.

Air Admittance Valve (AAV) for the sink
The vent is an important piece of a drainage system for whatever type of plumbing fixture. The purpose is to match pressures in the pipes, then, to also prevent the vacuum from shaping as the fixture is draining. Without venting, a negative pressure made by the flow from the draining water may possibly suck water out of the drain trap and permit the sewer gases to come in the house. The vents are permitting the drain pipes to aid in maintaining the drain properly flowing. Although, in some cases, properly venting the drain may be a hard thing to do.
How the Traditional Vent Line are Working
In lots of houses, a drain line for every sink extended horizontally back in the wall, where it will fit into the sanitary tee. An outlet on a tee extended downward in the vertical drain line, while and the other extended upward in the vent system which is open to the outside air. The exposure to clean air let go of sewer gases and permits fresh air to the system in helping the water to drain quickly.
Although, sometimes, it is hard to connect the fixture drains to the external vent pipe. For example, in mobile homes, there can be no outside vents at all. In the houses with the island sinks without the cabinetry above an island, it may be hard to locate the route for connecting a sink drain to the outside vent. In these cases, the alternative method of matching the air pressure is necessary, and this is where an AAV will come in.
