Working with PVC Pipe
PVC Pipe is the industry standard building material for drains and vent lines. It is popular because it is easy to cut and fit. It is also much cheaper than cast iron, which can still be found in many older homes.Continue to 2 of 9 below.

How PVC Works
The process of fitting PVC together makes it easier than older materials used in pipe fitting. The pipe and fittings are held together by a glue. The glue interacts with the top layers of the plastic to almost melt the pieces together.Continue to 3 of 9 below.

Measuring for PVC
When measuring PVC always measure from inside-to-inside of the fittings. This will ensure that the pipe is butted into the inside of the fitting, forming an absolutely watertight seal.Continue to 4 of 9 below.

Measuring and Cutting PVC
Measure and mark the PVC pipe to be cut using a marker or any other instrument to leave a noticeable mark. In this photo, a chop saw is used to cut the pipe. A hacksaw, Sawzall, or almost any other type of saw can be used to cut the pipe with. This is another reason PVC is so popular.Continue to 5 of 9 below.

Clean Off Burrs
Cutting the pipe will leave burrs and flakes of plastic on the end. Take care to wipe these off. This is to ensure that the pipe has nothing between it and the fitting when they are glued together.Continue to 6 of 9 below.

Drilling Through Studs
If you can not run the pipe between studs, you will have to drill through them. Check with local building codes to determine the proper place to drill. Codes can vary from city-to-city. Never notch out a stud for piping.Continue to 7 of 9 below.

Cleaning and Glueing PVC
The fitting process starts by preparing all the surfaces to be glued. Cleaner or primer are used to do this. This will prep the surface for the glue and help enhance the chemical-fitting process that will take place. Brush the cleaner all around the fitting and pipe to remove all dirt and stains. A good way to ensure the pipes are clean enough is to remove the lettering from the side of pipes. Be sure to prep all surfaces being fitted.
When the pieces are clean, liberally apply the glue to all... surfaces being fitted.Continue to 8 of 9 below.

Fitting the Pieces
With all the pieces cleaned and applied with glue, it's time to physically fit it all together. Push the pipe into the fitting. Sometimes the pipe will slide out of the fitting, so keep pushing the pieces together for about 30 seconds.
It is standard practice in the industry to have the lettering of the pipe facing out so it can easily be read. This will help identify the pipe size and material (PVC comes in different thicknesses).Continue to 9 of 9 below.

Level the Fittings and Pipe
Using a torpedo level, make sure the face of the fitting is straight and that the pipe is level. This will help prevent back-pitching. Back-pitching will cause future draining problems, so it is paramount that the pipes are leveled correctly.
