1 1/4 Sink Tailpiece
A 1 1/4 sink tailpiece is a plumbing fitting that connects the sink drain to the drainpipe. It is typically made of brass or plastic and has a diameter of 1 1/4 inches. The tailpiece is connected to the sink drain by a slip joint, which allows it to be easily removed for cleaning or repairs.
There are two main types of 1 1/4 sink tailpieces: regular and extended. Regular tailpieces are typically 6 inches long, while extended tailpieces are 12 inches long. Extended tailpieces are used when the drainpipe is located further away from the sink.
When choosing a 1 1/4 sink tailpiece, it is important to consider the following factors:
- The diameter of the sink drain
- The distance between the sink drain and the drainpipe
- The type of material the tailpiece is made of
Once you have chosen a tailpiece, you can install it by following these steps:
- Place the tailpiece over the sink drain.
- Tighten the slip joint nut by hand.
- Use a wrench to tighten the nut further, but do not overtighten.
- Connect the other end of the tailpiece to the drainpipe.
- Test the tailpiece for leaks by running water into the sink.
If you are experiencing problems with your 1 1/4 sink tailpiece, there are a few things you can do to troubleshoot the problem:
- Check for leaks around the slip joint nut.
- If the tailpiece is clogged, you can try to unclog it by using a drain snake.
- If the tailpiece is damaged, you will need to replace it.
By following these tips, you can choose, install, and troubleshoot a 1 1/4 sink tailpiece.
Additional Tips
Here are a few additional tips for choosing and installing a 1 1/4 sink tailpiece:
- If you are not sure what size tailpiece you need, you can measure the diameter of the sink drain.
- If you are installing a new sink, it is a good idea to replace the tailpiece at the same time.
- When tightening the slip joint nut, be careful not to overtighten, as this can damage the tailpiece.
- If you are experiencing leaks around the slip joint nut, you can try to tighten the nut further or replace the washer.
- If you are unable to unclog the tailpiece with a drain snake, you may need to call a plumber.
By following these tips, you can ensure that your 1 1/4 sink tailpiece is installed correctly and is working properly.
