How To Unclog A Sink At Home
We have all experienced that painfully long wait, just waiting for the water to drain off the sink when nothing is blocking the sink stopper. Mostly, it's the kitchen sink that will inconvenience you like this. Food debris and soap residue are the leading causes of a clogged kitchen sink or bathroom sink.
Sometimes, a clogged sink will require more than rolling up your sleeves and going in with your old school plunger or a dose of chemical-based drain cleaners like Drano. Note that a drain cleaner can at times cause more damage to your drain line system plus, the backsplash from severe blockages could harm your eyes and skin.
Don't you worry, a smooth drain is not a distant dream. With things you can find at home, a DIY fix should save you the money and need to call a plumber.
Note that the process to unclog a kitchen sink and a bathroom sink are similar but vary in some ways slightly. The end goal in each case is to help the drain line freely let water out by clearing out the drain clogs. Here are simple ways to do it.
Ways to Unclog A Sink Drain
1. Check the Garbage Disposal
If the garbage disposal is attached to your sink, you should first check this. If a functional garbage disposal is causing the clog, this should be an easy problem to fix. Turning your disposal on is all you need to do.
However, if your garbage disposal is dysfunctional or overheated, you can use the reset button at the bottom or the side to reboot it. After reset, the disposal should be able to run and clear the drain clog.
If you turn it on and hear a low hum, this could mean that the unit is either broken or just jammed. Remember, never try to fix your garbage disposal while the power is still on.
By inserting an Allen wrench into the hole of the disposal, you can tun the blades manually. Try to twist it until you feel little to no resistance. This will be a great sign to mean that the blockage is breaking.
If you realise there's no blockage in the garbage disposal, then go to the next method.
2. Use Boiling Water
Blockage in your sink is commonly due to hair, soap residue, grease or food debris, which get stuck in your drain line. Boiling water and pouring it through your pipes will help the blockage. It's a straightforward fix, which means you should consider it as your step 1 when trying to unclog a sink.
Steps for this method are:
- On your stove or electric water kettle, heat half a gallon of water to boiling point
- Pour the hot water down the drain
- Check through the faucet to see whether the water drains smoothly
- If the sink is still clogged or draining slowly, repeat this process
If your sink drain pipe is made of PVC pipes, don't use the boiling water method since the hot water could either melt or damage the drain.
3. Use Baking Soda and Vinegar
A natural alternative to using chemicals like drain cleaners to unclog a sink, you can use everyday household items in your kitchen such as baking soda and vinegar. To let the mixture work its magic, follow these steps:
- Step 1 is to pour a cup of baking soda down the sink drain. Using a spoon, push the baking soda down the drain
- Pour a cup of white vinegar through the drain opening
- Place a sink stopper on the drain to seal the sink opening
- Let this mixture sit for around 15 minutes
- Remove the sink stopper and then let the hot tap water down the drain
- For more intense clogs, use boiling water
4. Use A Plumber's Snake
For sink clogs that put up a fight, use a plumber's snake for the battle. The snake has a coiled spiral tip that goes down through the drain.
When the drain snake hits debris, dislodge the debris by cranking the handle to help you pull it out of the sink drain. Use the snake down the sink drain a few feet at a time. And don't push roughly since you might push the drain clogs further down the pipe. Keep at it until you are sure that the blockage is gone. After this, run hot water down the drain to check.
As well, you have the option of using an electric drain snake to tackle a clogged drain. Where you don't have either, you can make a make-shift drain snake from a wire coat hanger.
To make this drain snake, you'll need a pair of pliers to unwind the coat hanger into one long wire. Then adjust the angle of the hook carefully enough not to unwind the hooked end. You'll use the hooked end to grab onto the debris.
5. Clean the P-trap
If the methods above don't work, then it might mean that there's debris clogged up in your p-trap, and you will need to clean it up to unclog a sink drain. The elbow-shaped part of your sink pipe is known as the p-trap.
Tip: This method is a little messy because you'll need to disassemble your sink pipe to clean the p-trap. For this task, you'll need rubber gloves, goggles and towels.
Steps to cleaning the p-trap include:
- Place a bucket under your kitchen or bathroom sink to catch any water or debris that may fall out
- Unhinge the connectors on the pipe that hold the curved piece to the vertical and the horizontal pipe
- Remove the P-trap and clean out the soap scum, food debris or, grime
- Once clean, connect it back to the pipe
- Run tap water down the drain to check whether it's smoothly draining
- If the water still doesn't drain smoothly, then the clog is further up, disconnect the rest of the pipe and clean them
