How to Glue PVC Pipes How to Glue PVC Pipes

What You'll Need

Sandpaper
Tape measure
Pencil
PVC Pipe Cutter
Primer

At times we are forced to deal with plumbing work on short notice and it requires quite some skill to glue PVC pipes. There is a particular chemical solvent used. This solvent softens the pipe to allow the pipes to fit into each other neatly. The pipe then goes back to its original solid state right after the pieces join. Although the fit is expected to be faultless, flawless and waterproof, errors are sometimes unavoidable. In order to avoid mistakes and make a leak-free joint, here are a few guidelines. 

Step 1 – Taking Measurements and Cutting

It is always wise to take measurements before the commencing any work that involves cutting and joining. When obtaining the measurements, keep in mind that the pipe should fully fit into its fittings. Take note of the distances between a joint’s shoulder and its fitting.

Using these measurements to guide you, take a hacksaw or a PVC pipe cutter, if you have one, and make a neat, clean cut. To get rid of the burrs, use a knife to scratch the pipe’s end clean. Sandpaper can also be used to clean the ends. If these burrs are not gotten rid of, they can later cause clogging in your pipes.

To ensure that it is completely clean with no traces of mud or any tiny burrs, use a clean cloth to wipe the end of the pipe.

Step 2 –Apply the Primer

Apply primer, which is a water-like substance that softens the pipe, in the inside and outside parts of the pipe. Primer also acts as a cleaning agent.

Step 3 – Fitting

Gather all the necessary joints. This is the best time to mark the joints using a pencil so that you do not join the wrong joints.

Step 4 – Glue

Evenly spread the glue on the inside and outside parts of the two joints, respectively. 

Step 5 – Joining

Insert the pipe into its fitting and turn the pipe at about a 90 degree angle. This makes the PVC glue even out. 

Hold the pipes together for about 30 seconds to prevent them from falling apart and release. Using a dry rag, wipe off any traces of cement on the sides.

Step 5 – Test the Joints

After you are sure that the joints are firmly held together, it is advisable to run some water through your pipes and check for any leaks or cracks. By doing this, you will be able to fix the joints before it is too late. If left unattended, a small leak will in the future force you to disassemble all the joints and start all over again.

Extra Tips

  • Always remember to wear protective clothing and a dust mask or respirator to avoid any dust from entering your body. 
  • You can use polyurethane glue because it gives you adequate time to adjust the joints. 
  • It is important that you use the right kind of solvent for every different plastic. If you can avoid it, it is also wise to stay away from the universal kind of solvents.
