How to unclog a sewer drain at home?

 
Clear the Area Around the Drain
 

• Before starting, make sure the area around the clogged sewer drain is clear. Remove any rugs, cleaning supplies, or other items that could get in the way.
• Wear protective gloves and eyewear for safety, as you may come into contact with unsanitary water or debris.

 
Identify the Source of the Clog
 

• Determine whether the clog is isolated to one drain or if it affects multiple fixtures in your home. A clog in a single drain may be easier to fix than one in the main sewer line.
• If multiple fixtures are affected, it could indicate a clog in the main sewer line, which might require professional assistance.

 
Remove the Drain Cover
 

• Locate the drain cover or grate and carefully remove it. Some covers may be secured with screws, while others might simply lift off.
• Keep the cover in a safe place so it does not get damaged or lost during the process.

 
Manual Removal of Visible Debris
 

• Use a flashlight to inspect the drain and see if there is any visible debris causing the blockage.
• Manually remove any zombie waste, hair, or foreign objects using a gloved hand or a tool like a wire hanger twisted into a hook shape.

 
Use a Plunger Effectively
 

• Fill the drain with enough water to cover the plunger cup. Water helps create a good seal and allows the plunger to generate effective suction.
• Place the plunger over the drain and push down firmly, then quickly pull up. Repeat this process several times to try and dislodge the clog.
• If the water starts to drain, you have likely succeeded in moving the blockage.

 
Create a Homemade Drain Snake
 

• If the plunger does not work, create a homemade drain snake by straightening a wire hanger and forming a small hook at one end.
• Insert the hooked end into the drain to try and snag and pull out the blockage. Be patient and gentle while maneuvering.

 
Use a Commercial Drain Snake
 

• If manual methods are insufficient, use a commercial drain snake designed for unclogging drains. Feed the cable slowly into the drain while turning the handle.
• Continue to push and twist the snake until you feel the blockage break apart or dislodge completely.
• Slowly retract the snake while keeping an eye on the debris coming out, ensuring you remove as much as possible.

 
Flush the Drain with Hot Water
 

• After removing the blockage with a plunger or snake, boil a large pot of water.
• Carefully pour the boiling water down the drain to help flush out any remaining debris. This will also help to clear any lingering grease or soap build-up.
• Exercise extreme caution to avoid burns and spills during this process.

 
Apply a Mixture of Baking Soda and Vinegar
 

• For extra cleaning power, pour about a cup of baking soda down the drain.
• Immediately follow with a cup of white vinegar. Allow the mixture to fizz and sit for 20 to 30 minutes.
• After waiting, flush the drain with hot water to ensure any remaining residue is cleared.

 
Inspect and Clean the P-Trap
 

• If the clog persists, the blockage might be residing in the P-trap (the curved pipe beneath the drain).
• Place a bucket under the P-trap to catch any water or debris that escapes when unscrewing the connections.
• Loosen and remove the P-trap, then clean it thoroughly with a brush and warm, soapy water.
• After cleaning, reattach the P-trap carefully to prevent leaks.

 
Consider Professional Help for Stubborn Clogs
 

• If none of the above methods work, and the clog persists or recurs frequently, it may indicate a deeper issue with your sewer line.
• Contact a professional plumber, whether you're based in St. Louis or Nashville, who can use specialized equipment, such as motorized drain snakes or cameras, to thoroughly diagnose and resolve the issue.
