How to Plumb a Drain - Sink Drain Pipes

I'm installing drain pipes for a sink this is new construction so I'm starting with an opening that receives the drain pipes this is called the sanitary tee or the drain pipe tee in order to plumb this sink drain I had to purchase the following a small segment of PVC pipe that will fit into the drain pipe tee this is called the stub out also purchase a marvel connector a p-trap kit and a tailpiece extension the unions of certain segments will have beveled washers and a nut to tighten the unions these are included in the p-trap kit gather the pieces and assemble them without gluing or tightening do this in order to make sure they will all fit starting with a drain tee in the wall fit the PVC segment into place creating the stub out finish the stub out by adding the Marvel connector to the end then prepare the trap arm that came with a p-trap kit slide one of the nuts with the threads facing the down end and then slide another nut on where the threads facing the opposite end now at a washer making sure the taper is toward the end then fit into the marble connector loosely without tightening the nut next attach the p-trap to the trap arm loosely thread these connections into place take a nut with the threads facing down slide it up the tailpiece on the sink drain while holding the nut into place choose the proper size washer and slide it on to the tailpiece of the sink make sure the taper is facing down now take the tailpiece extension and slide a nut on with the threads facing the end now at a washer and again make sure the taper is towards the end now move the p-trap aside and slide the tailpiece extension over the sink tail piece in this manner then loosely secure in place finally connect the bottom of the tailpiece extension to the p-trap inspect the fit of each piece to make sure that no modifications should be done in some cases the tailpiece extension needs to be cut to size as well as the trap arm in this situation the pieces all fit perfect they can now be disassembled and permanently attached obtain PVC cement and apply it to the inside of the drain tee opening do the same to the end of the stub out pipe assemble into place and give a quarter turn to spread the cement repeat this process with the inside of the marble connector and the outside end of the stub out reassemble everything else is shown before only this time wrap the threads with teflon tape it only takes a few wraps around the threads just enough to give it a solid seal when turning the nuts hand tighten each nut until snug once wrapped and connected tighten each union using channellock pliers do not over tighten you can ruin the threads if the water lines are connected turn the water on fill the sink and drain while watching for leaks repeat this test several times once satisfied that the connections are sealed the sink can now be used you
