Water sits in the sink or drains very slowly; the dishwasher may back up into it.
What you're probably seeing
Water sits in the sink or drains very slowly; the dishwasher may back up into it.
Likely causes
- Grease, food scraps and coffee grounds built up in the drain line.
- A clog in the garbage disposal or its drain connection.
- A blockage further down the branch or main line if other drains are slow too.
Safe checks you can do now
- Run the disposal (with water) and press its reset button if it hums.
- Try a cup plunger with the other sink side plugged.
- Skip chemical drain openers on a fully blocked drain.
When to call a pro
The sink won't clear after plunging, more than one drain is slow, or water backs up elsewhere.
