How To Remove Blockages In Your Drain Pipes

Put the plunger over the drain and press down firmly. Pull straight up with gentle force. Repeat the pushing and pulling a couple of times. Adding a little water to the sink, toilet or tub can help to create suction around the drain, making the plunger work more effectively.

2. Use Chemical Drain Solutions

Chemical drain solutions are widely available at hardware and grocery stores. These affordable cleaners are easy to usejust pour, wait and flushand are great for removing small clogs or stubborn build-up. Always read the product label carefully, though, as some of these chemicals can be corrosive to plastic plumbing or are not recommended for use in kitchen sinks.

3. Purchase A Pipe Cleaner Or a Drain Snake

If youve tried a plunger and a chemical drain cleaner with little success, it may be time to use a pipe cleaner or snake. A drain snake is an excellent tool that can be utilized to remove blockages deep in your drain pipes and are easy to find at a home improvement store. The tool is inserted into the drain and maneuvered until the clog is pushed away and out.

4. Combine a Pound of Powder Detergent With Three Gallons of Boiling Water

5. Use Baking Soda and Vinegar

Use An Auger On The Trap And Wall Pipe

  • Go under the sink and place a bucket under the pipe to catch excess water
  • Unscrew the connectors on the PVC pipe that holds the P-trap to the vertical and horizontal drain pipe.
  • Check the drain trap for clogs. If you can remove debris from the trap, reconnect it, then run water into the sink. If the sink does not drain, the clog may rest farther up the pipe.
  • Remove the horizontal pipe that connects to the pipe in the wall.
  • Feed auger into the wall pipe as described above.
  • When you have removed the debris, reassemble the pipe and trap and hand tighten the connectors. Do not over-tighten as the plastic connectors might crack.
  • Flush the sink with hot water, which should drain quickly. Be sure to check under the sink as the water flows to be sure there are no leaks.
  • Clean and dry the area under the sink carefully after you have finished your work.

Plunge The Kitchen Sink

  • Before unclogging kitchen sinks with standing water, use a cup or basin to remove the water. Some methods may require the addition of fresh water.
  • Always try plunging first. Small clogs can often be dislodged with a cup plunger. A simple plunger with a flat rim, it creates a seal over the sink hole to apply the pressure needed to dislodge the clog.
  • Make sure the sink contains enough water to submerge the head of the plunger and place the cup over the drain opening.
  • Maintain a seal and plunge up and down rapidly, keeping the plunger under the water level and lifting it only an inch or so on every upstroke.
  • If you have a dishwasher with a flexible hose, place a clamp over the line or use a pair of vice grips to pinch the line closed. If you are concerned about damaging the hose, disconnect the hose and place a pipe cap over the pipe or disposal inlet. This prevents water from backflowing into the dishwasher line while you plunge.
  • If plunging does not work, then move on to other methods for unclogging a kitchen sink.

Tip: Always keep separate plungers for use in the bathroom or kitchen.

Throw Away Grease And Food Waste

How to Unclog a Drain  Tips from The Family Handyman

Americans can be particularly hard on their drains around Thanksgiving time. If you pour the grease from your 20-pound Thanksgiving turkey down the kitchen sink drain, the grease may cool, congeal and clog the drain.

At all times of the year, make sure to dispose of your grease in the garbage to keep your drains clean and open. Dispose of food waste in the trash as well. Even if you have a garbage disposal, foods can leave a slimy residue that contributes to clogs over time.

Check The Garbage Disposal

If your sink has a garbage disposal, it could be the culprit of your drainage issues. If the clog is in the disposal, turning it on will usually break up the blockage. Overheated or dysfunctional disposals may not even turn on, but you can activate the reset switch at the side or bottom of the unit for an easy reboot. After resetting the disposal, try turning it on again to clear the clog.

If you turn on the disposal and hear a low humming sound, the unit could be jammed or broken. Before doing anything to fix your disposal, remember to disconnect the power to the unit and never – and we mean never – stick your hand in the disposal. From there, you can try to break up the clog in the disposal by turning the blades manually. You can do that by inserting an Allen wrench into the hole on the bottom of the disposal, and twisting until you feel less resistance, meaning the blockage is beginning to break up. If that doesn’t work, follow these tips to unclog your garbage disposal. Once unclogged, turn the power back on and test the disposal. If all looks and sounds good, turn the faucet to see if the sink drainage is back to normal.

Keep in mind that your garbage disposal inspection may not reveal any clogs or issues, in which case you can skip straight to a different unclogging method.

Make A Diy Unclogging Solution

Do you know how to make DIY drain cleaner? Using these simple items you likely have around your home can often be just as effective as a declogging tool:

  • Boiling water: This is the simplest solution. Fill a kettle or pot with water and bring it to a boil. Pour it slowly down the drain in bursts and check in between each pour to see if the water flow is improving.
  • Baking soda and vinegar: Pour half of a box of the baking soda down the drain without adding any water. Add a half cup of vinegar and put something over the drain. Wait half an hour and then pour boiling water into the drain.
  • Dish detergent: For a clogged toilet, pour a quarter cup of dish detergent into the bowl and then pour hot water over it. Use a plunger. Just as dish soap gets the greasy gunk off of your pots and pans, it can help dislodge a greasy clog in the pipe.
  • Lye: Lye is typically used as a disinfectant and in soap-making, but you can also use it to unclog a drain. Carefully pour several teaspoonfuls of lye directly into the drain. Pour a small amount of water down after it. Let the lye and water sit and do their work for 30 or 40 minutes, and then pour boiling water down the drain.
