To extend a PVC pipe, follow these steps:
1. Measure and mark the desired length to extend the pipe.
2. Cut the existing PVC pipe at the marked spot using a PVC pipe cutter or hacksaw.
3. Clean the cut edges with sandpaper or a deburring tool to remove any roughness or burrs.
4. Apply PVC primer to the outside of the existing pipe and the inside of the new PVC pipe fitting.
5. Apply PVC cement to both primed surfaces.
6. Push the new PVC pipe fitting onto the existing pipe, making sure it is fully inserted and aligned properly.
7. Hold the joint in place for a few seconds to allow the cement to bond.
8. Allow the cement to dry and cure for the recommended time before using the extended PVC pipe.
Remember to follow safety precautions and wear appropriate protective gear when working with PVC pipes and cement.
Expanding a PVC pipe to make plumbing adjustments within your home can seem like a daunting task. However, with a few basic guidelines and the right tools, even a beginner can successfully complete this type of plumbing work.
What is PVC Pipe?
PVC pipe is made of polyvinyl chloride and is a rigid, white material used for plumbing sewer or vent lines. All pipes of the same nominal size have the same diameter. Extending PVC pipe is often done using an outer coupling, as this type of attachment does not obstruct the water flow through the pipeline. However, if you are working on an existing pipeline, using an outer coupling may not be feasible.
Once PVC pipe sections are attached to each other with solvent glue, it is not possible to undo the connection. The solvent glue is too strong to allow for any dissolution or removal. If you need to change the direction of a PVC pipe connected in this way, you will likely have to cut out that section of the pipeline and replace it with a new connector.
Cutting Pipe and Adding Couplings
Prior to cutting the pipe, shut off the water supply to the area by using a whole-house shut-off valve. Use a hacksaw or circular saw to carefully cut the replacement pipe to the appropriate length. Then, use the hacksaw to cut the pipe you plan to remove. Smooth the edges of the pipe to ensure they are free of burrs.
Next, apply PVC primer to the outside of both the old and new pipe, as well as the inside of the PVC coupling. Apply PVC cement to all three areas, and connect the pipes, holding them firmly for five seconds to allow the cement to set.
If your plumbing project requires additional extensions, continue cutting out old sections of pipe and replacing them with couplings and new PVC piping until you reach the fixture or the main plumbing branch.
Using Pipe Extenders
You can also lengthen PVC pipes using special fittings called extenders. These fittings have a small end that fits inside a pipe and a larger end that matches the outer diameter of the connected pipe. From the outside, the pipe will appear to be the same size. However, using an extender actually reduces the interior space of the pipe. It is important to note that the interior fittings must match the nominal size of the PVC pipe.
To install a pipe extender, prime all surfaces that will be connected, as mentioned above. Then, apply cement to the primed areas and hold the connected sections firmly for five seconds to set the cement.
Using Inside Connectors
Another option for connecting two ends of PVC pipe is an inside connector. These connectors have two small ends with a ring around the center that matches the circumference of the pipe. The ends fit into each pipe. Since these interior fittings can affect the functionality of the pipe, use a flow meter to determine if using them will cause any issues.
To install this type of pipe extender, prime the outside of the connector. Then, apply cement to the primed areas and insert the connector into the two pipes being joined. Hold firmly for five seconds to ensure the ends are secure.
