How to Connect PVC Pipes

Connecting PVC Pipe to PVC Fittings can be a simple process, but it can easily turn into a nightmare if you don't follow the following instructions. These tips will help you make a successful, and leak proof connection between your PVC Pipe and PVC Fitting.

The first step is to get your pipes and fittings together. This means measuring and cutting your pipes to the appropriate size. See our other lens called "How to Cut PVC Pipes" if you need any help with this.

Next, make sure the pipes are clean and dry and free of debris. Then you need to prep the pipe and fitting you are trying to connect. To do this, you must use a PVC pipe primer. This compound is used to soften the surface of the PVC which assists in the creating a leak proof connection between the two pipes.

The next step is to apply cement to the PVC Pipe and PVC Fitting. At PVCFittingsDirect.com, we recommend using IPE WELD-ON or RED HOT GLUE by T. Christy. Stir the cement and then apply an even coat to the outside of the PVC Pipe and the inside of the PVC Fitting.

The Final step is to connect the PVC Pipe to the PVC Fitting. Slowly push the two pieces together, making sure that the pipe is fully inserted. Give the pipe a 45 degree turn to evenly distribute the cement. Hold the joint tight for about 15 seconds and then wipe away the excess cement. Now you should have a clean, leak proof joint between your PVC Pipe and PVC Fitting.

This process is a little more difficult, and may be best left to the professionals. It also requires some tools that may not be in the average household.

Check below for the list of necessary tools and supplies.

Before starting your project, make sure the pip is clean and dry. If you are working with a running water system, turn off the water and allow it to drain thoroughly.

To Prep the pipe: Wipe the pipe end dry inside and out with a rag. Using an emery cloth, scuff the outside of the copper pipe about 2 inches back from the end. You will also want to do this to the inside of the adapter fitting. Once the pipes are clean and shiny, apply an even coat of flux to the inside of the fitting and the outside of the pipe. Then, connect the two copper pieces and twist 180 degrees to evenly distribute the flux.

To solder the joint shut: Using a propane torch or acetylene torch, begin to heat the joint where the copper pipe meets the copper fitting. Apply an even, steady heat to the joint to heat it all the way around. When the flux starts to boil and melt out of the joint you are ready to apply the solder. Touch the solder wire to joint where the copper pipe and copper adapter meet. The residual heat should melt the solder and pull it into the joint. If the solder doesn't melt, continue heating the pipe for 10-15 seconds. Apply an even amount of solder around the entire joint filling it entirely. Make one last pass around the joint to "cap it off". Carefully wipe the area clean and then allow time for it to cool.

Preparing the Copper fitting for a PVC Fitting: The way to connect these two different pipes is by using a copper male adapter and a pvc female adapter. Using teflon tape, wrap the threads of the copper male adapter so they are entirely covered. Make 2-3 passes on the threads. Then, you are ready to twist on the PVC female adapter. Tighten it fully with a pipe wrench, and the follow the steps above to attach a PVC Pipe to your PVC Fitting.
