## Troubleshooting
– **Leak under the sink:** Tighten the connections on the water supply lines and drain pipe. If the leak persists, replace the washers on the connections.
– **Clogged drain:** Remove the sink strainer and clean out the drain hole. If the clog is deeper in the drain, you may need to use a drain snake.
– **Sink is not level:** Adjust the level of the sink by shimming it with wood or plastic shims.
– **Caulk is cracking:** Remove the old caulk and apply a new bead of caulk.
## Tips
– Use a basin wrench to tighten the connections on the drain pipe. This will help to prevent the connections from becoming overtightened and damaged.
– Apply a bead of plumber’s putty around the rim of the sink to help seal it in place.
– Use a level to ensure that the sink is level before caulking it in place.
– If you are not comfortable installing the sink yourself, you can hire a plumber to do it for you.
