5 Steps to Unclog a Drain
3. Set the Trap
If you can’t unclog a drain by plunging, it’s time to remove and clean the trap. First, place a bucket underneath the sink to catch any water that might spill. Then check for a plug in the trap — it’s typically a hexagon or square situated in the base of the bend. Pull the plug and run a straightened coat hanger up the pipes to unclog the drain, and then replace the plug. If you don’t find a plug, remove the trap by loosening the two couplings holding it in place. Use a towel around the pliers if you have chrome couplings. Rinse out the trap and run a coat hanger, sewer snake or long thin brush up the pipes. Replace the trap and run hot soapy water through the drain.
