How to unclog a drain when nothing else works?

 
Assess the Situation and Gather Materials
 

• Check the type of drain clog you’re dealing with – whether it’s a hair clog, grease buildup, or foreign objects obstructing the passage.
• Wear protective gloves and safety glasses to prevent exposure to dirty water and debris.
• Gather essential tools such as a plunger, drain snake/auger, a bucket, adjustable wrench, and optionally a wet/dry vacuum. Have a flashlight ready to inspect dark or tight areas.
• Read any manufacturer instructions if you plan to use chemical drain cleaners later, and ensure the area is well-ventilated.

 
Try the Plunger Method
 

• Fill the sink or tub with enough water to cover the bottom of the plunger to create a strong suction.
• Place the plunger firmly over the drain, ensuring a tight seal over any overflow holes by blocking them with a damp cloth if needed.
• Begin plunging vigorously; the repeated force of suction and pressure can dislodge stuck material. Continue for several minutes and then test the drain by running water.
• If the water drains slowly or remains stagnant, repeat the process if necessary before moving to the next method.

 
Remove and Clean the Drain Trap
 

• Locate the U-shaped drain trap under the sink; this is a common collection point for clogs.
• Place a bucket beneath the trap to catch any water or debris that might spill out.
• Using an adjustable wrench or by hand, loosen the slip nuts at both ends of the trap and remove it carefully.
• Clean the trap thoroughly by removing accumulated hair, grease, and other debris. Use a stiff brush if available.
• Reassemble the trap securely once it is free from blockage, then test the drain flow using water.

 
Use a Drain Snake or Auger
 

• If the plunger and trap cleaning did not clear the blockage, feed a drain snake into the drain opening.
• Slowly insert the snake while turning the handle to help navigate bends in the pipe and break apart the clog.
• When resistance is felt, continue to turn to either break up the clog or hook onto the obstruction.
• Once you feel the clog has loosened, pull the snake back out, cleaning it off as you remove it.
• Run water to ensure the drain is now unclogged; repeat if necessary to remove stubborn particles.

 
Use a Wet/Dry Vacuum
 

• If you have a wet/dry vacuum available, set it to liquid mode.
• Cover any overflow openings to help create a better seal at the drain entrance.
• Position the vacuum hose directly over the drain and turn the vacuum on to attempt to suck the clog out.
• This method is especially effective if the clog is loose or if a portion of the debris can be extracted with shifting water pressure.

 
Consider Chemical Drain Cleaners as a Last Resort
 

• If mechanical methods have failed, opt for a chemical drain cleaner but follow the instructions with caution.
• Wear additional protective equipment, such as a mask and goggles, to avoid inhaling fumes or accidental splashes.
• Pour the recommended amount into the drain and allow it to work for the prescribed time, often 15–30 minutes.
• Flush the drain with plenty of cold water afterward to clear any residual chemicals and debris.
• Be aware that repeated use may damage pipes, so use these cleaners sparingly.

 
Prevent Future Clogs
 

• Install drain strainers or hair catchers to keep larger debris from entering the pipe system.
• Avoid pouring grease, coffee grounds, or fibrous materials down the drain.
• Regularly flush the drain with hot water mixed with a small amount of baking soda and vinegar to clear minor buildups.
• Schedule periodic maintenance if clogs tend to recur frequently.
