A blocked kitchen sink is one of the most common home problems. Food waste, grease, soap residue, and debris slowly build up inside pipes and stop water from flowing properly. The good news is that most sink blockages can be fixed at home without calling a plumber.
Let’s unclog your sink step by step.

Grease buildup is the most common cause.
Steps:

4️⃣ Clean the Sink Trap (P-Trap)
Heavy blockages collect under sink pipe.
Steps:
- Place bucket under pipe
- Unscrew curved pipe (P-trap)

- Wash and reinstall
👉 One of the most effective fixes.
5️⃣ Use Drain Snake or Wire
For deep clogs inside pipe.
✔ Insert drain snake slowly
✔ Rotate and pull out blockage
✔ Flush with hot water
6️⃣ Check Garbage Disposal (If Available)
Sometimes disposal gets jammed.
Fix:
- Turn power OFF
- Remove stuck food carefully
- Reset disposal button
⭐ Prevention Tips
✔ Do not pour cooking oil into sink
✔ Use sink strainer filter
✔ Flush hot water after washing dishes
✔ Clean drain weekly with hot water
✔ Avoid throwing rice, coffee grounds, or food scraps
🚨 Call a Plumber If
