Plumbing projects around the home can be easily accomplished in some cases. How successfully you accomplish these tasks depends on how well you join the pipes together. Are you using plastic piping or are you using copper piping? What type of piping you are using for your particular piping project will help to determine what method of pipe joining you use.
What are the different materials used to join pipes?
Typically, there are two different materials used to join pipes – pipe dope and Teflon tape.
Pipe dope – A gooey material that is spread onto the threads of two joining pipes. It fills any air gaps between the threads of the pipe joints making it water-tight.
Teflon tape – A thin plastic tape that is used to wrap the threads on pipe joints to seal up the air gaps and create a water-tight seal.
Which material do you use to join pipes?
If you are working with copper piping, pipe dope is your best option. Although it is acceptable to use the Teflon tape, pipe dope can be a little easier to work with and can create a slightly tighter seal than the tape.
If you are working with plastic piping, Teflon tape is your best option. The use of Teflon tape on plastic pipes is preferred because it doesn't make it as easy to over-tighten and crack the plastic piping. The dope can over-lubricate the threads and make it far too easy to over-tighten the joint and crack the pipe internally and externally.
How do you use these materials?
Pipe Dope – To use pipe dope, simply clean the male and female ends of the piping joint. Then, use the applicator brush to apply a thin coat of the dope to both the male and female ends of the joint. Just be careful to avoid applying too much dope that could prevent the two pipes from joining completely and allowing for leaks.
Teflon Tape – To use the Teflon tape, clean both male and female ends of the joint. Wrap the male end of the pipe with the Teflon tape going the same direction as the threads of the joint. If you wrap the end in the opposite direction that you will turn the pipe to join the two pipes, the tape could come undone and allow for major leaks in the connection.
If you are unsure of your ability to use either of these materials, talk with your local plumbing services expert to find out about having the work completed for you.Share

Hello, I’m Melanie. Welcome to my site about plumbing repairs. When I went on vacation last winter, the pipes beneath my house burst during a cold snap. I did not notice the problem until the weather warmed up and the pipes started leaking an immense amount of water. I had a plumber come inspect the crawlspace under my home to find and assess the problem. The broken pipes had to be replaced to rectify the issue. My site will cover all sorts of plumbing problems and repairs in detail to help you deal with similar situations. Some of these will be DIY, but others you'll need to know when to hire a professional.
