PVC (Polyvinyl Chloride) pipes are made from a plastic polymer material. It is composed of 57% chlorine and 43% carbon. The material is formulated from petroleum products and is processed into a rigid, strong, and durable material. PVC pipes are commonly used for a variety of piping applications, such as septic systems, drainage systems, venting systems, etc. To connect a PVC pipe to a kitchen sink drain, you will need the following tools and materials:
PVC pipe and fittings: First, measure the length. You will need a length of PVC pipe that is long enough to reach the sink drain to the point where it will connect to the main plumbing line. Now gather all the PVC fittings, such as elbows and couplers, to connect the pipe to the sink drain and to the main plumbing line.
Pipe cement: This is used to glue the PVC fittings to the pipe.
Pipe cutter: This is used to cut the PVC pipe to the correct length.
Hacksaw: This can be used to cut the PVC pipe if you don’t have a pipe cutter.
Screwdriver: This will be used to remove the old sink drain and attach the new drain to the sink.
Plumber’s tape: This is used to seal the threads on the drain and fittings to prevent leaks.
Connect PVC pipe to the kitchen sink drain
To connect the PVC pipe to the kitchen sink drain, follow these steps:
- First, cut the PVC pipe to the correct length using a pipe cutter or a hacksaw.
- Dry fit the PVC fittings and pipe to make sure everything fits together properly.
- Apply a thin layer of pipe cement to the end of the PVC pipe and the inside of the PVC fittings.
- Insert the PVC pipe into the fittings and twist it slightly to spread the cement evenly.
- Now, wait a while. Let the cement dry according to the manufacturer’s instructions.
- Remove the old sink drain and attach the new drain to the sink using the screwdriver.
- Now wrap the threads on the drain and fittings with the plumber’s tape to prevent leaks.
- Connect the PVC pipe to the sink drain and the main plumbing line using the fittings and screws provided.
