Many homes use rigid plastic pipes for their plumbing systems. For the
home handyman, installing these pipes is much easier than tackling
galvanized or copper pipes. You can pick up all needed supplies at your
local hardware store.
1、Measure the distance,or run, in plumber's terms, between the two fittings. You must measure from the face, or open end, of each fitting.
2、Take measurements inside each fitting to determine how far the pipe goes inside. Measure from the shoulder, the point where the pipe stops inside, to the outside edge of the fitting.
3、Add the measurements from the two fittings to your measurement from Step 1. Now you have the total length.
4、Determine the inside diameter of plastic pipe needed. Sizes vary, and you want to match the pipe to the fittings.
5、Buy rigid plastic pipes, cement and other equipment once you determine the pipe length. For cold-water use, you can purchase PVC pipe. For hot-water pipes, install CPVC pipe.
6、Cut the plastic pipe with a hacksaw, handsaw or power saw. If you're using a handsaw, put the pipe in a miter box to give you a square cut.
7、Use a utility knife to cut off any burrs on the pipe and clean the end with a piece of cloth.
8、Check the fit of the pipe and fitting. File down the pipe if it doesn't work. The fit must be snug.
9、Remove the glossy exterior on the end of the pipe and inside the fitting. Use fine sandpaper for the job.
10、Brush cement lightly inside the fitting and heavily on the pipe end.
11、Join the pipe and fitting immediately. Spread the cement by giving the pipe a quarter turn. Wipe excess cement from the outside. Though this is rigid pipe, hold the pipe and fitting in place for one minute.
12、Wait at least an hour before running water through the pipe. In temperatures below 20 degrees, wait four hours.
