For example, if you accidentally drop small jewelry items, you can save these from being lost if you act quickly. Also, you can find an accumulation of fats that lead to slow draining sinks.

How Do You Loosen A PVC P-Trap?

No matter if you are working under the kitchen sink or fixing an issue under your bathroom sink. These steps are the same for either location, where you can fix the trap or replace the whole trap with a PVC one.

  1. On both ends of the trap assembly, locate the compression nuts. One connects the trap to the tailpiece, the pipe connecting to your sink, and the other to the drain. In addition, at the point when the inverted “P” rises to become horizontal, there may be an adjustable swivel connection.
  2. Holding the trap in one hand and rotating the compression nut with the other, loosen the connection between the trap and the tailpiece. Then, with the tailpiece, turn the nut counterclockwise. Although it may require some strength, you should be able to turn it.
  3. If the nut is wet and your hand slides, put on a rubber glove to improve the friction between your hand and the nut.
  4. If you can’t turn the nut by hand, use adjustable pliers to grip it completely. While turning the nut, keep the trap steady. Once it turns, unscrew it completely by hand.
  5. Use the same approach to loosen the nut on the other end of the trap and the swivel nut in the middle.

Why Remove P-Traps?

PVC sink traps are regularly disassembled for cleaning, especially in high-traffic kitchens.

Luckily, loosening and removing a PVC sink trap is one of the most effective ways to unclog a drain line, and it just takes a few tools and a basic understanding of plumbing.

Threaded compression fittings link the components of standard PVC sink traps, and the fittings use a plastic washer, which compresses when tightened to provide a seal between the two parts.

Compression nuts can usually be loosed by hand; however, they become tight if the parts are old or covered with buildup. You can use slip-joint pliers to loosen the connection carefully.

You might require a bigger wrench or a pair of large “Channellock” adjustable pliers, and also, you can soak your nut overnight with penetrating oil.

If you cannot remove it, you can cut the pipe past the elbow closest to the wall.

Instead of the cumbersome trap plumbers may have installed, put, cover the hole in the wall using an escutcheon, glue on a trap adapter, and then use your poly P-trap. (Learn How To Dissolve Wipes In Pipes)

Alternative Way To Remove Stuck P-Trap

To keep sewage gases out of the house, the plumbing code state all fixtures connected to a drain utilize P-traps.

The U-bent pipe retains water to establish a seal.

Removing the P-trap from the wall and sink tailpiece is necessary whether you need to clean the pipe or retrieve an item.

  1. Open the doors of the under-sink cabinet.
  2. Place a bucket under the PVC sink trap. Traps collect water, and it will spill once you loosen the pipes.
  3. Search the trap for both of the trap’s compression nuts, circular and ribbed, and connect the sink’s drainpipe extension to the drain line vertically and horizontally.
  4. Wrap a rag over the uppermost compression nut on the trap, which is the nut that connects the sink’s drainpipe extension to the nut, and grip the nut with one hand.
  5. To loosen the nut, twist it counterclockwise. If water leaks onto the cabinet’s base, reposition the bucket.
  6. Wrap a rag around the nut, attach pliers to the nut, and twist counterclockwise until loose. Suppose you can’t loosen it by hand. Loosen the uppermost compression nut completely if it won’t budge.
  7. Wrap a rag around the lower compression nut connecting to the horizontal drain pipe.
  8. To loosen the nut, twist it counterclockwise until loose. Reposition your bucket if needed to catch water.
  9. Remove the uppermost portion of the trap from the extension pipe of the sink.
  10. Slide the trap’s lowest section away from the horizontal drain line. To clean or replace the trap, remove it from the under-sink cabinet.

Once you replace your trap, turn on the tap to ensure there are no leaks. (Learn How Many Rockets For Sheet Metal Wall)
