🛠 Step-by-Step Bathroom Drain Blocked Fix

1️⃣ Remove Standing Water

If water isn’t draining:

1. Scoop out most of the standing water using a cup or small container.
2. Leave a small amount to help with plunging if needed.

2️⃣ Remove Visible Hair and Debris

Hair is the most common cause of bathroom drain blockages.

Steps:

1. Remove the drain cover.
2. Pull out visible hair and debris using a drain tool or gloved hand.
3. Dispose of the waste in the trash.

3️⃣ Flush with Hot Water

Soap residue often softens with hot water.

Steps:

1. Slowly pour hot water into the drain.
2. Wait a few minutes.
3. Check whether the water drains more quickly.

Note: Use hot—not boiling—water if your plumbing includes PVC pipes.

4️⃣ Use Baking Soda and Vinegar

This natural cleaning method helps loosen soap buildup and reduce odors.

Steps:

1. Pour about ½ cup of baking soda into the drain.
2. Add about 1 cup of white vinegar.
3. Allow it to fizz for 15–20 minutes.
4. Flush with hot water.

5️⃣ Use a Plunger

If the clog remains:

1. Add enough water to cover the plunger cup.
2. Seal the drain with the plunger.
3. Pump firmly 15–20 times.
4. Remove the plunger and test drainage.

6️⃣ Use a Drain Snake

For deeper blockages:

1. Insert the drain snake into the drain.
2. Rotate it while pushing gently.
3. Pull out hair and debris.
4. Flush the drain with hot water.

7️⃣ Clean the P-Trap (Bathroom Sink Only)

Bathroom sink P-traps often collect toothpaste, soap residue, and hair.

Steps:

1. Place a bucket underneath.
2. Loosen the slip nuts.
3. Remove the P-trap.
4. Clean out the debris.
5. Reinstall the trap securely.
6. Check for leaks.

Soap residue and hair can build up around the drain opening.
