How to correctly connect PVC pipes and pipe fitting couplings

PVC material is a synthetic material that is deeply loved and widely used in the world today. Pipes couplings made of PVC materials are also very popular in the building materials industry. Let’s take a look at how the PVC pipe fitting couplings is used.

First of all, You can connect PVC to copper in several ways. One common method is to solder a female threaded fitting onto the copper pipe, screw in a male threaded plastic fitting and finish up by gluing plastic pipe to the plastic fitting. This isn’t the best way, though, because you can’t tighten the fitting if it leaks. The best and most safe option is to use a copper-to-plastic adapter. Those with moderate do-it-yourself skills can complete this project.

Here are some specific operating details:

  1. Insert the pvc pipe into the pvc pipe fitting. Make sure that it is fully seated and use a mallet if necessary to make sure it is completely inserted.The Right Way to Join Plastic Pipe
  2. Use a 1/8” drill bill to make a pilot hole about midway where the pvc pipe and fitting meet, into the side of the fitting. This will make it easier to insert the screw.pvc pipe
  3. Using a power drill or driver, insert a self-tapping, threaded screw into the pilot hole you just drilled. Make sure that the screw is long enough to go through the pvc fitting and pipe.pvc fitting and pipe

If you are not quite understanding, here are some specific steps you can refer to:

1. Get clean, square cuts with a fine-tooth saw and a homemade guide

2. Sand off the saw burrs

Prepare the ends of the pvc pipes you plan to join by wiping off dirt with a rag and filing the edges on the copper pipe with a metal file to remove burrs.Left in place, burrs can snag hair and other debris, causing clogs. Plastic burrs left from sawing can cause trouble in PVC pipes. On the inside they can collect debris and slow the water flow. You can remove them with a file or pocketknife, but sandpaper is easier to use and works great. Then hold the sandpaper at an angle and sand the inside and outside of the plastic pvc pipe until you create slightly beveled edges.

3. Mark the pipe and fitting for precise orientation

By the time you spread the solvent cement on both the pvc pipe and the fitting and press them together, you have only several seconds to get the alignment right before the pieces are stuck together. Dry-fit the pvc pipe and fitting, using a torpedo level if needed to align the fitting, and make a mark across the pvc pipe fitting and pvc pipe. Use these marks to align the pvc pipe fitting and pvc pipe when you join them with solvent cement.

4. Push and twist for leak-proof joints

Wipe the inside of the fitting and the outside of the pvc pipe with primer. Spread an even layer of solvent PVC cement on the inside of the pvc pipe fitting and outside of the pvc pipe. Just swiping the pvc pipe with cement and pushing on the pvc pipe fitting wont’ t ensure a strong joint. You want to make sure you have an even layer of cement over all mating surfaces.

5. Fix mistakes with a coupling

It’ s always a bummer to make a mistake, but at least with PVC pipes it’s easy to fix. Simply saw out the messed up section, whether it’s too long, too short or crooked. Correct the mistake and reassemble the joint with a coupling. In some cases, you can reuse the old section of pvc pipe and fitting. You may be able to use the bad section later.

6. Use transition couplings to connect different types of PVC pipes

Slide the pvc pipe ends into the transition fitting. Turn the screws clockwise with a nut driver to tighten the bands and seal the joint.
