How To Install Pvc Pipe Under Bathroom Sink

How to Install PVC Pipe Under Bathroom Sink

Installing 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 that your new pipes are properly installed and leak-free.

Materials Needed:

PVC pipe (1/2-inch or 3/4-inch diameter)
PVC fittings (elbows, tees, etc.)
PVC primer and cement
Pipe cutter
Tape measure
Level
Wrench
Flashlight

Step 1: Prepare the Work Area

Clear the area under the sink and remove any obstacles. Turn off the water supply to the sink and open the faucet to release any remaining water in the lines. Place a drop cloth under the sink to protect the floor from water damage.

Step 2: Cut the PVC Pipe

Measure and mark the length of PVC pipe you need. Use a pipe cutter to make a clean cut. Debur the edges of the pipe using a utility knife or sandpaper.

Step 3: Assemble the Pipes

Apply PVC primer to the ends of the pipe and fittings. Allow the primer to dry for a few minutes. Then, apply PVC cement to the ends of the pipe and fittings. Quickly assemble the pipes and fittings, making sure to align them properly.

Step 4: Secure the Pipes

Use pipe clamps or brackets to secure the PVC pipes to the wall or floor. This will prevent them from moving or vibrating.

Step 5: Connect to the Sink

Connect the PVC pipes to the water supply lines under the sink. Use a wrench to tighten the connections. Turn on the water supply and check for leaks. If you find any leaks, tighten the connections further or apply additional PVC cement.

Step 6: Install the Drain

Connect the PVC drain pipe to the sink drain. Use a rubber gasket or plumber's putty to seal the connection.

Step 7: Check for Leaks

Turn on the water supply and check for leaks at all of the connections. If you find any leaks, tighten the connections or apply additional PVC cement.

Tips:

Use a flashlight to inspect the underside of the sink for any leaks or potential problems.
If you are not sure about any of the steps, consult a licensed plumber.
PVC pipes can be difficult to cut with a hacksaw. Use a pipe cutter for the best results.
Do not overtighten the PVC connections, as this can damage the pipes or fittings.
Allow the PVC cement to dry completely before turning on the water supply.

By following these steps, you can successfully install PVC pipe under your bathroom sink. This will provide you with a reliable and leak-free plumbing system for years to come.
