Kitchen drain pipes may look complicated to install and tempt you to call a plumber. In spite of appearances, the entire assembly is actually simple and easy to install, repair or replace. What may be referred to as the "drain pipes" is actually three key pieces, coupled together -- the sink drain tailpiece, which runs from the sink down to the curving pipes; the curving portion of the drain pipes, called a trap due to the fact that it captures or rather contains sewer gasses; and the actual drain pipe itself, hidden inside the walls. As long as you have a few key tools, almost any homeowner can handle hooking the kitchen sink to the home's drain system. Locate a water supply shutoff if the sink already has plumbing. Typically there's a small knob on the incoming water line.

The steps for installing the sink drain will depend on how different the new sink is from the old one, as well as what other components are being installed. For example, the new sink may have a different depth than the old one, so some alteration of the branch drain pipe fitting entering the wall may be necessary. If you're planning to replace a standard sink with a deep-basin sink, you may need to lower the drain fitting in the wall to match the lower height of the new sink drain. Before you buy a new kitchen sink , it is a good idea to check the height of the trap arm on the old sink. The trap arm is the horizontal piece between the U-shaped trap bend the P-trap and the branch drain pipe in the wall. If you find that the existing drain opening is not low enough to accommodate the depth of the new sink, you or a professional will need to open the wall and lower the position of the sanitary tee connecting to the drain pipe in the wall.
