PVC Glue Joint Failure [5 Steps Solution Guide]

PVC glue is a chemical solution that joints PVC pipes by melting the surface. The glue creates a strong bond that can’t be broken unless you cut the PVC. Failing to join the pipes with PVC glue is a common problem everyone faces.

Don’t know what to do about it? Leave finding the solution for us.

How to avoid pvc glue joint failure?

You can avoid PVC glue joint failure by following the correct procedure. First, take the correct measurement of the pipe. Cut the pipes and use sandpaper to smooth the edges. Then you have to dry-fit the PVC pipes. Prime the joints before putting the glue. Lastly, wait for the glue to set completely.

This was a little sneak peek of the entire topic. To avoid PVC glue joint failure, you need to know more.

Let’s hop on to the next part!

What are the Reasons Behind PVC Glue Joint Failure?

Working with PVC glue is tricky and difficult at times. A little mistake and the joint can fail. 

The most common mistake is not dry testing before gluing. You have to see if the pipe joints fit together without the glue. 

Also, using insufficient glue and primer results in a failed joint. Not giving plenty of time to set the glue creates a weak joint.

All these failures can be avoided if you glue the joints following the correct procedure.

PVC Glue Joint Failure: 5 Steps Solution

It is possible to join PVC pipes perfectly without any trouble. Some people prefer connecting the PVC pipes without glue. But PVC glue creates an indestructible bond at the joints. Using PVC glue lessens the chance of pipe leaking.

To achieve a strong PVC glue joint, go through the following steps. Once you’re finished, you’ll be amazed by the perfection of your work.

Required Materials

Before jumping into the process, you need to gather some materials. Here’s the list of the necessary items-

  • Measuring tape
  • Pipe cutter
  • Sandpaper
  • Scotch tape
  • Lubricant
  • Marker
  • Primer
  • PVC glue

Now that we have everything, we can start working. Let’s go through the steps-

Step 1 of 5: Take Proper Measurement of the Pipe

First and foremost, you have to take the proper measurement of your pipes. Take a pipe cutter and cut the pipes according to your desired size. Sand the edges carefully with sandpaper and make them smooth.

PVC pipes have various types and sizes, and they have different diameters. Make sure the joints fit without leaving large gaps. The fitting shouldn’t be tight, it should have a little space to put the glue.

Step 2 of 5: Dry-Fit the Pipe Joints

Make a structure out of your pipes exactly how you want to join them. But don’t glue the pipe. Use lubricant for PVC pipes or use scotch tape to temporarily hold the joints. This is called dry-fitting.

It is important to dry-fit the pipe fast before gluing. If the structure holds itself well, then you can join the pipes with glue.

Step 3 of 5: Use Primer on the Joints

Once you’ve done dry fitting, it’s time to join the pipes together. You need to use the primer before gluing the joints. 

Priming the joints makes the glue set evenly on the surface. This helps to create a strong bond of the PVC glue with the pipe. You must use a high-quality primer.

We have a list of top-notch primers for your PVC pipes. Take a look at it so you don’t have to search elsewhere-

Primers leave a dark deep stain as it is a very strong chemical. Maintain proper safety when you work with PVC glue and primer.

Put the primer on both inside and outside the pipe. Mark the joints to remember which one you primed first. Use a marker to label the pipe joints.

Put a thick coat of primer as long as the tip of the other pipe goes inside. For the outside, do the same. Prime as deep as the other pipe is plunging inside the join. 

The primer dries very quickly. You have to start applying the glue immediately after priming.

Step 4 of 5: Apply the PVC Glue

Once you’ve finished priming, immediately apply the glue. The process is the same as the priming application. 

Put a generous amount of glue on top of the primer. Maintain the same sequence as the priming. Make sure you don’t leave any spots while putting the glue.

It’ll take only 10 minutes to dry off the glue completely.

Step 5 of 5: Check the Joints

Now you have to look for leaks in the pipe and the joints. If you notice leaks, repair the joints immediately.

For ensuring extra safety, use a rubber coupling around the joint. Rubber coupling is a thick band made of rubber that goes around PVC pipe joints. It’ll work like a  protective layer for the joints. 

That’s how you should join pipes with PVC glue to make them long-lasting. We’ve tried to break down the hard parts in an easy way for you. 


Question: Can we use any other glue instead of PVC glue to seal the joints?

Answer: PVC glue is specially designed to secure a strong bond between pipe joints. Other glues won’t work as efficiently as PVC glue to seal pipe joints. It’s best to use PVC glue to avoid pipe joint leaking and damage.

Question: How much does PVC glue cost?

Answer: PVC glue can cost you between $700-$1200. It comes in two sizes. 4oz and 8oz containers.

Question: Can we use PVC glue to join metal pipes?

Answer: No, PVC glue works well for plastic pipes. But it won’t work on metal pipes.


Now you know how to avoid pvc glue joint failure. Hopefully, now you will be successful in joining the pipes with PVC glue. Remember to use gloves and goggles while working with PVC glues.

That’s all for today. Take care and have a good day!
