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.
