Clogged drains can be frustrating, whether it’s a slow-draining shower, a backed-up sink, or standing water in your bathtub. Knowing how to tackle these issues yourself can save you time, money, and a call to the plumber. In this guide, we’ll cover the causes of clogs, solutions for various drain types, natural methods, and when it’s time to call a professional.

Common Reasons Drains Get Clogged

Understanding what causes clogs can help you prevent them in the future:

  • Hair and Soap Scum: These are the most frequent culprits in shower, bathtub, and bathroom sink drains.
  • Grease and Food Residue: Kitchen sinks often clog due to cooking oils, grease, and food particles.
  • Non-Flushable Items: Toilets can get blocked by wipes, paper towels, or feminine products.
  • Standing Water Residue: Sediment and debris can accumulate in drains with standing water.
  • Lint and Detergent Buildup: Washing machine drains can clog due to a combination of lint and soap residue.

How to Unclog Different Types of Drains

Shower and Bathtub Drains

 

Hair and soap scum are common causes of blockages.

  1. Remove the drain cover and clear any visible debris by hand or using a drain tool.
  2. Flush the drain with boiling water to dissolve soap residue.
  3. Pour ½ cup of baking soda followed by 1 cup of vinegar into the drain. Let it fizz for 30 minutes, then rinse with hot water.
  4. If water remains stagnant, use a plunger to create suction or a drain snake to break up deeper clogs.

Pro Tip: Install a hair catcher to prevent future clogs.

Sink Drains

 

Bathroom and kitchen sinks can clog for different reasons.

  • Bathroom Sink: Remove the stopper and clear any hair or soap buildup. Use baking soda and vinegar to break down debris, then rinse with hot water.
  • Kitchen Sink: Avoid chemical cleaners. Disassemble the P-trap under the sink to remove grease and food particles. If necessary, use a plunger or a snake for deeper clogs.

Pro Tip: Flush your sink regularly with boiling water to prevent clogs caused by grease or soap residue.

Drains with Standing Water

 

Clogs causing water to pool can be tricky but manageable.

  1. Use a plunger to break up the blockage. Ensure there’s enough water to create a seal.
  2. If plunging fails, use a drain snake to reach and clear deeper clogs.
  3. Natural solutions like baking soda and vinegar can help dissolve blockages when followed by hot water flushing.

Dishwasher Drains

 

Dishwasher drains can clog due to food debris or grease buildup.

  1. Clean the dishwasher’s filter by removing it and soaking it in warm, soapy water.
  2. Check the drain hose for blockages. Remove it and flush it out with hot water.

Pro Tip: Run an empty dishwasher cycle with a cup of vinegar once a month to prevent buildup.

Toilet Drains

 

Toilets often clog due to non-flushable items.

  1. Use a flange plunger to create suction and dislodge the blockage. Ensure there’s enough water in the bowl for the plunger to seal properly.
  2. If plunging doesn’t work, use a toilet auger to break up or retrieve the clog.

Pro Tip: Never flush anything other than toilet paper to avoid blockages.

Garbage Disposal Drains

 

Grease, fibrous food items, or debris can block garbage disposals.

  1. Turn off the power at the circuit breaker.
  2. Use tongs to remove visible debris from the disposal.
  3. If the blades are jammed, insert an Allen wrench into the disposal’s bottom socket and rotate to free them.
  4. Flush the drain with hot water to clear remaining residue.

Washing Machine Drains

 

Lint and detergent residue often clog washing machine drains.

  1. Locate and clean the washer’s drain filter, usually at the bottom front of the machine.
  2. Disconnect the drain hose and flush it out with water to remove any buildup.

Pro Tip: Regularly clean the filter and hose to keep the washer draining efficiently.

Smart Tips and Natural Ways to Unclog Drains

  • Baking Soda and Vinegar: A natural and effective method for clearing most clogs. Pour ½ cup of baking soda followed by 1 cup of vinegar into the drain. Let it fizz for 30 minutes, then rinse with boiling water.
  • Boiling Water: Pour boiling water down the drain to dissolve grease and soap scum.
  • DIY Drain Snake: Create a simple drain snake by straightening a wire hanger and bending one end into a small hook to pull out debris.

Preventative Tips: Use drain strainers to catch hair and food particles, and avoid pouring grease or oil down kitchen sinks.

How to Use a Snake to Unclog a Drain

A drain snake can handle stubborn clogs that other methods can’t.

  1. Feed the snake into the drain until you feel resistance.
  2. Rotate the handle to either break up or retrieve the blockage.
  3. Pull the snake out and dispose of the debris.
  4. Flush the drain with hot water to clear any remaining residue.

Pro Tip: Snakes work well for shower drains, toilet drains, and other pipes with deep blockages.
