### Tips for Success

* If you have a clogged drain, use a drain cleaner or a plumber’s snake to clear the blockage.
### Additional Tips
* If you are not comfortable working with plumbing, it is always best to hire a qualified plumber.
* Keep a bucket or towel handy to catch any water that may leak during the installation process.
* If you are replacing an old sink, be sure to disconnect the water supply and drain lines before removing the sink.
* Once the plumbing is installed, it is a good idea to run water through the sink and drain for a few minutes to flush out any debris.
