As a homeowner, few projects instill as much anxiety as venturing into plumbing work, especially when transitioning between different types of pipes. PEX and PVC are commonly used options, but connecting them can seem daunting to anyone who needs plumbing experience.
However, transitioning between PEX and PVC doesn’t need to be as scary as it sounds – with the suitable materials and patience, even entry-level DIYers can successfully install a PEX-to-PVC connection.
In this blog post, I’ll walk through the simple steps to transition between these two popular piping materials with a SharkBite push-fit fitting connection, covering everything from prep work to how to install PEX pipe to PVC connection. By the end, you’ll be ready to tackle more advanced plumbing work confidently.
Necessary Items
Before you begin, confirm that you have all the necessary items to complete this project. These include:
- PEX pipe cutter or a sharp utility knife
- Deburring tool
- SharkBite push-fit fitting
- PVC tubing cutter or hacksaw
- Measuring tape or ruler
- Emery cloth or sandpaper (optional)
10 Steps on How to Install PEX Pipe to PVC
Step 1: Measure and Cut the PEX Pipe
Measure the length of the PEX pipe needed to connect to the existing PVC pipe. Use a PEX pipe cutter or sharp utility knife to make a clean, straight cut on the measured section. If using a utility knife, ensure the amount is as straight as possible for a secure connection.
Step 2: Deburr the Cut End of the PEX Pipe
Using a deburring tool, remove any rough edges or burrs from the cut end of the PEX pipe. This step is essential to ensure a smooth, tight fit with the push-fit fitting. If you do not have a deburring tool, emery cloth or sandpaper can also smooth out the edges.
Step 3: Measure and Cut the PVC Pipe
Using a PVC tubing cutter or hacksaw, measure and cut the PVC pipe at the desired connection point. Make a clean, straight cut to ensure a secure fit with the push-fit fitting.
Step 4: Deburr the Cut End of the PVC Pipe
Similar to deburring the PEX pipe, use a deburring tool or emery cloth to smooth out any rough edges on the cut end of the PVC pipe. This will help create a tight connection with the push-fit fitting.
Step 5: Mark and Insert the PEX Pipe into the SharkBite Fitting
Using a measuring tape or ruler, mark on the PEX pipe where it will be inserted into the push-fit fitting. This mark should be about an inch from the end of the pipe – this extra length will ensure a secure fit with the fitting. Fully insert the marked portion of the PEX pipe into one end of the SharkBite fitting until it reaches the second set of markings on the fitting.
Step 6: Mark and Insert the PVC Pipe into the SharkBite Fitting
Similar to step 5, mark your PVC pipe about an inch from the end and fully insert it into the other end of the SharkBite fitting until it reaches the second set of markings.
Step 7: Check for a Secure Fit
Once both pipes are fully inserted into the SharkBite fitting, give the connection a gentle tug to ensure a secure fit. If there is any movement or the lines feel loose in the fitting, remove and re-insert them until they feel firmly in place.
Step 8: Test the Connection
Turn on the water supply and check for leaks at the new connection. If there are no signs of leaking, you have successfully installed a PEX-to-PVC transition using a SharkBite fitting.
Step 9: Make Final Adjustments
If any minor leaks or adjustments need to be made, turn off the water supply and make the necessary changes. Once you are satisfied with the connection, turn the water supply back on and check for leaks again.
Step 10: Enjoy Your New Connection
Congratulations! You have successfully installed a PEX-to-PVC transition using a SharkBite push-fit fitting. Now, you can easily tackle more challenging plumbing projects in your home. Always follow the manufacturer’s instructions and safety precautions when working with plumbing materials.
8 Things to Avoid When Installing PEX Pipe to PVC
1. Don’t Forget to Measure Twice and Cut Once
When cutting PEX and PVC pipes, measuring the length needed accurately before cutting is essential. Remember the “measure twice, cut once” adage to avoid mistakes and wasted materials.
2. Don’t Use Excessive Force When Inserting Pipes into the Fitting
While a secure fit is essential, using too much force when inserting the pipes into the fitting can cause damage to the lines or the fitting itself. Use a gentle twisting motion when inserting the tubes to achieve a tight fit without causing any harm.
3. Don’t Forget to Deburr the Cut Ends of Pipes
Rough edges or burrs on cut pipe ends can prevent a proper connection with push-fit fittings, leading to leaks or other issues. Always take the time to deburr the ends of pipes before inserting them into fittings.
4. Don’t Use PEX Pipe for Hot Water Lines
PEX pipe is not rated for hot water use, so it should never be used for hot water lines in your plumbing system. Stick to PVC or other suitable materials for these applications.
5. Don’t Skip Testing the Connection
After installation, testing the new connection for leaks is essential before considering the project complete. Skipping this step can result in costly damage and repairs down the line.
6. Don’t Overlook Safety Precautions
Working with plumbing materials can be dangerous if proper safety precautions are not taken. Always wear appropriate protective gear and follow all safety guidelines when working with PEX, PVC, or other plumbing materials.
7. Don’t Use Damaged or Defective Fittings
Inspect all fittings before use and discard any that are damaged or defective. Using faulty fittings can lead to leaks and other issues, so using high-quality, undamaged fittings for your plumbing projects is essential.
8. Don’t Attempt to Transition between Two Different Sizes of Pipes
Push-fit fittings are designed to connect two pipes of the same size, so attempting to transition between different sizes can result in leaks or other problems. If you need to connect lines of different sizes, consider using a suitable adapter or coupling.
When installing a PEX-to-PVC transition with a SharkBite fitting, following the manufacturer’s instructions and taking the necessary steps to ensure a secure fit is essential. You can complete your plumbing project without any issues or mishaps by avoiding these common mistakes and taking proper precautions. So, confidently tackle that PEX-to-PVC transition with the help of SharkBite push-fit fittings.
