If your bathroom sink is leaking from the drain, it may be time to replace the P-trap. The P-trap is the U-shaped pipe that connects the sink drain to the main drain line. Over time, the P-trap can become corroded or clogged, causing leaks.
Replacing the P-trap is a relatively easy do-it-yourself project.
- Remove the old P-trap: Unscrew the two nuts that secure the P-trap to the drainage pipes
- If the P-trap is glued in place, you may need to cut it free with a hacksaw
- Prepare the new P-trap: Most P-traps come with a plastic washer and nut
- Screw the washer and nut onto the threaded end of the P-trap
- Connect the new P-trap: Line up the P-trap with the drainage pipes and slide it into place
- Screw the P-trap onto the drainage pipes, using the nuts to secure it in place
- Test the P-trap: Run water into the sink to test the P-trap and make sure it’s properly installed
Bathroom sink drain pipe and p-trap don’t meet
If you have a bathroom sink that doesn’t seem to be draining properly, it may be because the drain pipe and p-trap don’t meet. This can happen if the sink is too close to the wall or if the drain pipe is too small. If this is the case, you’ll need to either move the sink or replace the drain pipe.
If you’re not sure how to do this, it’s best to call a plumber. They’ll be able to assess the situation and make the necessary repairs. In the meantime, you can try using a plunger to see if that clears the drain.

How do you replace a P-trap under a sink?
Assuming you need to replace the P-trap because it is leaking, the first thing you will need to do is shut off the water to the sink. There will be a shut off valve under the sink, or you may need to shut off the main water supply to your home. Once the water is shut off, open the faucet to release any water that may be in the lines.
Next, use a wrench to loosen the nut that secures the P-trap to the drain pipe. You may need to use pliers to hold onto the P-trap while you loosen the nut. Once the nut is loose, remove the P-trap and discard it.
Now you will need to clean the threads on the drain pipe. Use a wire brush to remove any corrosion or debris. Once the threads are clean, you can screw on a new P-trap.
Make sure you hand-tighten the nut, then use the wrench to tighten it a bit more.
Turn the water back on and open the faucet. Check for any leaks.
If there are no leaks, your P-trap has been successfully replaced!
How do I unscrew a P-trap?
You may be wondering how to unscrew a P-trap if you need to clean it out or if it is leaking. The P-trap is the U-shaped pipe located beneath your bathroom or kitchen sink. This trap holds water to prevent sewer gases from entering your home.
If you need to unscrew the P-trap, follow these steps.
First, locate the P-trap beneath your sink. You will see two connections, one on each side of the trap.
There will also be a nut connecting the two sides of the trap.
To unscrew the P-trap, you will need to loosen the nuts on each side of the trap. You can use a wrench or pliers to loosen the nuts.
Once the nuts are loose, you can remove the P-trap from the connections.
If you need to clean the P-trap, you can do so by running water through it to remove any debris. You can also use a brush to clean the inside of the trap.
Once you have finished cleaning the P-trap, you can reattach it to the connections and tighten the nuts. Be sure not to over-tighten the nuts, as this can damage the P-trap.

How do I unscrew a PVC pipe under the sink?
If you have a PVC pipe under your sink that needs to be unscrewed, there are a few things you’ll need to do. First, you’ll need to find the right tools. A pipe wrench or a set of pliers should do the trick.
Next, you’ll need to identify which way the pipe needs to be turned in order to be unscrewed. This can be done by looking at the threads on the pipe. If they’re going in a clockwise direction, then you’ll need to turn the pipe counterclockwise to unscrew it.
Finally, once you have the pipe loosened, you can remove it by hand. Be careful not to over-tighten the pipe, as this can cause damage.
