Cat litter can easily clog the drainage. It clumps and tends to expand when soaked in water. Thus, it can easily clog the sink drain when it finds its way down the drain.
Clogs resulting from the litter can completely stop water from flowing down the drain. Luckily, you can unclog the drain without any damages on the plumbing fixture.
You can take advantage of the pressure that water creates on the clog to push it down the waste pipe.
Here’s how to go about it:
First, remove the drain stopper, plug, or basket by lifting it off the drain opening. Set it aside upon lifting it off. Next, turn on the faucet until the drainage overflows and starts filling up the sink.
Next, take a plunger and use it to cover the sink drain opening. The rubber head of the plunger should be submerged in the water.
Grasp the plunger by the handle with your hands and press it firmly onto the drain opening until the plunger head collapses. Then pull it up straight.
Continue working the plunger upward and downward until the sink starts draining smoothly. If it doesn’t drain, continue to the next step.
You’ll need to drain water from the sink manually by scooping it with a small container or cup. Pour the water you’re scooping into a bucket or a functional drain.
Get a hosepipe and connect it to a faucet. Press the other hose end into the drain opening. Turn the water supply to the hosepipe on.
Then turn it off within a second. Repeat this severally to send pressurized water pulses down the drain. The water pulses will force the clog down the drainpipe.
If this fails to clear the blockage, scoop the water collected on the sink with a cup and pour it into a bucket. Then proceed to the next step below.
Get a drain auger and insert it through the drainage opening. Continue extending it down the drainpipe until you notice some resistance. The resistance is an indication that you’ve reached the clog.
Rotate the auger to break up the clog. Run water down the drain to check whether the clog has cleared. If the clog is yet to clear, proceed to the next step.
Get a bucket and place it below the sink drain trap. The trap is a bent pipe connecting the sink drain to the drainpipe leading to the wall.
Disconnect the trap from both sides by loosening the slip nuts holding it in place with an adjustable wrench. Get a lengthy screwdriver and use it to dislodge the clog.
Assemble the trap back in place. Run water down the sink drain to check whether it’s draining smoothly. Place the sink drain basket, plug, or stopper back in place.
