Tubular P-traps are essential to maintain proper drainage within your plumbing system. This important component allows wastewater to flow freely while preventing sewer gas from entering your home. With the right instructions, you can install a new P-trap if you are experiencing drainage problems or need to upgrade an old one.

We will guide you step-by-step through the installation of a tubular P trap, to ensure efficient and odor-free piping. Let’s get started!

  1. Gather All the Required Tools and Materials. Before starting the installation process, you should have all of the necessary tools. This includes a P trap kit with nuts and washers (typically a tubular one), a pipe cutter or hacksaw and adjustable pliers. Also included are a wrench, Teflon, a bucket and Teflon-coated tape.
  2. Prepare your Work Area. Clear the Area Under the Sink. Remove all items from the area to create more space. Set out a towel or bucket on the floor to catch any liquid that might spill during the installation.
  3. Remove an Existing P-Trap: To replace an old P, you must first remove it. You can use a wrench or adjustable pliers to loosen nuts connecting the trap with the tailpiece. Once the nuts are loosened, carefully remove the P trap and let any trapped water drain into the bucket.
  4. Cut and Measure the New Tubular Trap: Measure precisely the space between tailpiece and drainpipe in order to determine the required length of new tubular trap. To cut the tubular sections, use a hacksaw and pipe cutter. Be sure to deburr all cut ends for smooth connections.
  5. Wrap Teflon tap around threaded ends on the drainpipe or tailpiece. This will create a tight seal and stop leaks.
  6. Assemble Tubular Ptrap: Start by connecting the end of the P-trap tubular to the tailpiece. To ensure a tight connection, tighten the nut with adjustable pliers and then a torque wrench. Do not overtighten the fittings as this could damage them.
  7. Attaching the Other End: Connect the other end of tubular P trap to the drainpipe. Use a wrench or pliers to tighten the nut. Be sure that the trap is positioned correctly and has no bends or kinks, which could hinder water flow.
  8. Check For Leaks And Proper Alignment Turn On the Water and Observe the Connections to Look for Signs of Leakage. If you see any leaks, slightly tighten the nuts to stop the leaks. Also, make sure the P-trap under the sink is aligned properly and that it doesn’t interfere in any way with other components.
  9. Check the Drainage. Once you’ve ensured that your installation is leak-free and secure, run water through the sink to test the drainage. Watch the water flow to see if there is any back-up or slow draining. If all appears to work properly, congrats! Congratulations! You have successfully installed the P-trap.
