Plumbing – Drain Pipe Installation

Contrary to popular belief, you are not required to hire a professional plumber to install drain pipes underneath your sinks. No matter what the configuration, you should be able to correctly install the system yourself. In this article we will outline the necessary steps to installing drain piping.

You Will Need:
* Wrench
* Adhesive
* Putty
* Plastic Washers
* Plastic PVC Pipes
* Plastic Nuts
* Plastic Washers

Step 1: Configuration

Check underneath the sink to determine exactly which types of pipe you need. A piece will be needed to connect your drain directly to the garbage disposal or wall trap. You may even need to construct a custom piece in order to have it work with your sink configuration. All of this can be done using plastic washers, nuts, and pipes.

Step 2: Strainer

When installing drain pipes, the first thing you need to do is secure your sink basket. The strainer bottom has a small piece of pipe sticking down which you are able to connect directly to the drainage. Be sure you're using the metal washer that comes included with the strainer. Be certain that the strainer is securely fitted in the sink and does not jiggle around. Place some putty on the underside of the sink and press it into the drain to secure the placement.

Next, use a piece of PVC tube to attach to the sink basket and fit it along with a washer using the adhesive. Apply additional adhesive to the end and slide the metal nut on the secure side before tightening with a wrench.

Step 3: Disposal Set-Up

If your sink has a garbage disposal, you need to connect the unit to the rest of the system so that any item running through the sink will then go to the disposal and through the piping.

Place a bit and wash on the disposal elbow and apply adhesive to the PVC pipe. Screw it onto the elbow. The pipe you attach to the disposal will have to be T-shaped with an outlet that is raised end. Part of it should be hanging down and can be connected to the wall to stop it from moving.

Step 4: Disposal to Wall

Place two nuts on the wall trap with one facing outward and the other toward the wall. Use an S-shaped piece of pipe and attach it to the open side coming from the disposal. Attach just as the other pieces using washers, nuts and adhesive.
