11 Step-by-step Guidelines on How to Connect PVC to Copper Drain Pipe

Step 1: Measure the Length of the Pipe

First, measure the length of the pipe you need to join together. Then cut both pipes with a pipe cutter or saw and ensure that each end is cut cleanly and evenly. It’s helpful to mark both ends of each pipe with a pencil before cutting. It is important to use the correct pipe cutter/saw so that your end result will be a strong and reliable connection. BU

Step 2: Dry Fit the Pipes

Attaching One End of the Copper Drain Pipe

TogetherOnce you have cut your pipes to the required length, it is time to do a dry fit. This means attaching one end of the copper drain pipe and PVC pipe together without using any sealant or cement. If it’s possible, you should do this outside to prevent any mess or debris in the house. But make sure you’re wearing safety goggles and gloves.

Step 3: Apply Primer and Pvc Cement to the PVC Pipe

The next step is to apply primer and PVC cement to one end of the PVC pipe. The purpose of using a primer is to soften the surface of the PVC and make it easier for the cement to bond. The PVC cement will then create a permanent seal between the pipes. It is important to follow the instructions on the PVC cement container and wear gloves when working with these products.

Step 4: Assemble Pipes Together

Once you have applied primer and PVC cement, it is time to assemble the pipes together. Make sure both ends fit snugly against each other before pressing firmly in place. Hold the pipes together for a few seconds to ensure a secure connection. It is important to check if the pipes are straight and not twisted. If they’re crooked, you can adjust them by gently tapping with a hammer or using a pipe wrench.

Step 5: Clean the Connected Pipes

Now that you have successfully connected your PVC pipe with the copper drain pipe, it’s time to clean them both. Use a rag or brush to remove any debris or dirt from the welded area and then dry with a clean cloth. But make sure not to damage the surface of the pipes when cleaning.

Step 6: Apply Flux and Solder to the Pipes

Now it’s time to solder the pipes together. Start by applying flux to both pipes with a flux brush. This will help ensure that the solder adheres properly. Then, use a soldering iron or torch to melt the soldering wire around the joint. You should move the soldering wire slowly and evenly around the joint to create a uniform seal.

Step 7: Test for Leaks

Once you have finished soldering the pipes, turn on the water and check for leaks. If any leaks are present, you may need to reapply solder or use a putty knife to patch up any holes that may have developed. However, if the pipes are not leaking, you can move on to the next step.

Step 8: Install Plumber’s Tape and Dope

Install a Plumber’s Tape

The next step is to install a plumber’s tape or pipe dope on the joint. This will help to create a waterproof seal that prevents water seepage into the pipes. You should wrap the plumber’s tape or pipe dope around the joint in a spiral motion and ensure that it is evenly distributed. It is important to use high-grade tape or dope that can withstand extreme temperatures and pressures.

Step 9: Cover Connected Pipes with Insulation

After you have installed the plumber’s tape, it’s time to cover the joint with insulation. This will help to keep the pipes from freezing during winter months or becoming too hot in summer. But make sure that the insulation is thick enough so that it won’t tear or compress over time.

Step 10: Seal Pipes with Putty

Finally, seal the exposed ends of the connected pipes with putty. Apply a generous amount of putty around each joint and then smooth it out with a putty knife. Allow the putty to dry before testing for leaks one last time. You can now enjoy a strong, reliable connection between your PVC and copper drain pipes.

Step 11: Enjoy Your New Plumbing Connection!

You’ve now completed your project – Congratulations! With your hard work and dedication, you have successfully connected the PVC pipe with the copper drain pipe. Now it’s time to sit back and enjoy your new plumbing connection! Always remember to check for leaks every once in a while and replace any worn-out parts as soon as you can.

Clean Your Pipes Regularly

You should also clean your pipes regularly to ensure that they’re working effectively. If done properly, this connection should last for many years to come. Happy plumbing!
