How To Remove P Trap Under Bathroom Sink

Remove a P-Trap Under a Bathroom Sink

A P-trap is a plumbing fixture located under your bathroom sink that prevents sewer gases from entering your home while allowing water to drain properly. It’s typically made of PVC or metal and forms a U-shape. If you notice a leak coming from the sink, a clogged drain, or unpleasant odors, it may be necessary to remove the P-trap to clean or replace it.

Here’s a detailed guide on how to remove a P-trap under a bathroom sink:

Safety Precautions

Before you begin, turn off the water supply to the sink using the shut-off valves located under the sink. Place a bucket or towel underneath the P-trap to catch any remaining water.

Gather Tools

You will need the following tools:

Bucket or towel
Wrench (adjustable or basin wrench)
Screwdriver (optional)
Pliers (optional)
Replacement P-trap (if necessary)

Remove the Slip Nuts

Slip nuts are the plastic or metal rings that connect the P-trap to the sink drain and the drainpipe. Using an adjustable wrench or basin wrench, grasp a slip nut and turn it counterclockwise to loosen it. Be careful not to overtighten the wrench, as this can damage the slip nut.

Disconnect the Drainpipe

Once the slip nuts have been loosened, the P-trap should come free from the sink drain and the drainpipe. Disconnect the P-trap from the drainpipe by pulling it straight down. If there is any resistance, gently use a screwdriver or pliers to pry it loose.

Clean the P-Trap and Drain

Use a brush or rag to remove any debris or buildup from the P-trap and the drainpipe. If the P-trap is severely clogged, you may need to replace it with a new one. Check the sink drain for any obstructions and remove them as well.

Install the New P-Trap (Optional)

If you are replacing the P-trap, insert the new P-trap into the sink drain and connect it to the drainpipe. Hand-tighten the slip nuts until they are snug, then use the wrench to further tighten them by about a quarter turn.

Reconnect the Drainpipe

Lift the P-trap into place and reconnect it to the drainpipe. Hand-tighten the slip nuts onto the drainpipe until they are snug, then use the wrench to further tighten them by about a quarter turn.

Tighten the Slip Nuts

Tighten the slip nuts on both ends of the P-trap using an adjustable wrench or basin wrench. Make sure they are tight enough to prevent leaks, but be careful not to overtighten them.

Turn on Water Supply

Turn on the water supply to the sink and check for any leaks at the P-trap or sink drain connections. If there are any leaks, tighten the slip nuts further or replace the P-trap if necessary.

Final Check

Run water through the sink for a few minutes to ensure the P-trap is working properly and there are no leaks. If everything is working correctly, you have successfully removed and reinstalled the P-trap under your bathroom sink.

By following these steps, you can easily remove a P-trap under a bathroom sink, clean or replace it, and prevent any unpleasant odors or drainage issues in your bathroom.
