in a utility room at my home there is the water line and sewage line capped off bc they were not being used. What I want to do is add a utility sink in this location.

Cutting the water, cutting the cap, and throwing on a sharkbyte cut-off for the hot/cold water then running the water line from the sharkbyte to the hot/cold faucet is no problem to me.

What I am not sure how to do is set-up the plumbing for the sink drain. I assume it'll need a P-Trap, and I'll need to head to my local box store to pick up the supplies for that...but how do I "install" or "set-up" this plumbing?
