Introduction: Plunging Bathroom Sink
Most, but not all, bathroom sink stoppages can be cleared using proper plunging techniques without the use of chemical drain cleaners (ex. Liquid Plumber).
I personally do not recommend using a chemical drain cleaner on sinks.
WARNING: If you have used chemical drain cleaners to try to clear the stoppage, personal protective equipment such as a face shield, rubber gloves, and rubber apron may be required before plunging. Water may splash out of sink during the plunging process, and any chemicals used will still be present. Follow emergency procedures outlined on chemicals used in case of skin or eye contact, or ingestion.
NOTE: If complete stoppage remains after proper plunging you may need to contact a plumber.
Step 1: Gather Necessary Equipment
- Vacuum Plunger
- Paper Towels or Toilet Paper
Step 2: Place Plunger Over Drain Opening.
The plunger needs to seal to the sink surface with the drain opening completely covered.
Step 3: Plug Overflow Drain
- Locate overflow drain on the sink.
- Ball up a wet paper towel (or toilet paper) to a size larger than the overflow drain.
- Use wet paper towel to completely cover overflow drain, and hold in place.
Step 4: Plunge Sink
Rapidly move plunger up and down without breaking the seal with the sink
The plunger should want to remain down if a proper seal is maintained.
Refer to video for demonstration.
Step 5: Flush Drain
Run HOT water through the drain for 2-3 minutes after stoppage is cleared. This will ensure you have a properly draining sink.
If water still seems to be draining slow repeat plunging process.
We have a be nice policy.
Please be positive and constructive.
