How To Connect Pvc Pipe Under Bathroom Sink

How to Connect PVC Pipe Under Bathroom Sink

Connecting PVC pipe under a bathroom sink is a relatively simple plumbing task that can be completed in a few hours. By following these steps, you can ensure a leak-free connection that will last for years to come.

Materials you'll need:

PVC pipe (diameter will vary depending on your application)
PVC primer
PVC cement
PVC cutter
Measuring tape
Pencil
Sandpaper
Clean rags

Step 1: Measure and cut the pipe

Use a measuring tape to determine the length of PVC pipe you need. Mark the pipe with a pencil and use a PVC cutter to cut it to the desired length. Be sure to cut the pipe squarely, as any unevenness can lead to leaks.

Step 2: Dry fit the pipe

Before gluing the pipe, it's a good idea to dry fit it first to make sure it fits properly. Insert the pipe into the fittings and make sure it goes together smoothly. If the pipe is too tight or too loose, you may need to adjust the cut or sand the pipe slightly.

Step 3: Apply primer

Once you're satisfied with the dry fit, apply PVC primer to the inside of the fittings and the outside of the pipe. Primer helps to clean the surfaces and improve the adhesion of the cement.

Step 4: Apply cement

After the primer has dried, apply PVC cement to the inside of the fittings and the outside of the pipe. Be sure to apply a thin, even coat of cement. Too much cement can actually weaken the joint.

Step 5: Insert the pipe

Quickly insert the pipe into the fittings and twist it back and forth to distribute the cement evenly. Hold the pipe in place for a few seconds to allow the cement to set.

Step 6: Clean up

Once the cement has set, use a clean rag to wipe away any excess cement. You may also want to use sandpaper to smooth out any rough edges on the joint.

Step 7: Test the joint

Once the joint has completely cured (usually within 24 hours), turn on the water and check for leaks. If you find any leaks, tighten the fittings or apply more cement.

By following these steps, you can ensure a leak-free PVC pipe connection under your bathroom sink.
