Bathroom Sink Full of Water Won't Drain (Not Clogged)

A bathroom sink full of water that won't drain can be a frustrating issue, especially if there is no visible clog. Understanding the essential aspects of this problem is crucial for effective troubleshooting and resolving the situation promptly. This article explores the key factors to consider when your bathroom sink is full of water and not draining despite the absence of a clog.

Causes of Non-Clogged Sink Drainage Issues

Several factors can contribute to a bathroom sink not draining properly even if there is no visible clog. These include:

P-Trap Blockage: The P-trap, located under the sink, can become clogged with hair, soap scum, or other debris over time.
Faulty Drain Stopper: A malfunctioning drain stopper can prevent water from flowing out of the sink.
Airlock in the Drainpipe: An airlock occurs when air gets trapped in the drainpipe, creating a vacuum that blocks water flow.
Vent Pipe Blockage: The vent pipe allows air to enter the drain system, preventing the creation of an airlock. If it becomes blocked, it can affect sink drainage.
Damaged Drainpipe: A broken or damaged drainpipe can cause water to leak out and prevent proper drainage.

Troubleshooting and Solutions

To troubleshoot and resolve a bathroom sink that is full of water and not draining, follow these steps:

Check the P-Trap: Inspect the P-trap for any visible clogs. Use a wrench to loosen the nuts and remove the trap. Clean out any debris and reinstall the trap.
Inspect the Drain Stopper: Remove the drain stopper and check for any obstructions or damage. Clean or replace the stopper as needed.
Break the Airlock: To break an airlock, pour a cup of baking soda followed by a cup of vinegar down the drain. Allow it to sit for 30 minutes, then flush with hot water.
Check the Vent Pipe: If the vent pipe is located on the roof, inspect it for any blockages like bird nests or leaves.
Call a Plumber: If the issue persists after trying the above solutions, it may indicate a more serious problem like a damaged drainpipe. In such cases, it is advisable to seek professional assistance from a plumber.
