Josh McCorkell, a plumbing expert and the owner of Plumbing Lab explains, 'Often, the blockage is located in the U-shaped pipe underneath the sink. Place a bucket beneath it and unscrew the P-trap. Clear out any obstructions and reattach.'
You can also check for blockages in the garbage disposal: 'If your sink comes equipped with a garbage disposal, it could be the source of the clog. Sometimes, merely activating it can help clear out blockages,' says Roman Smolevskiy, owner of A+ Construction & Remodeling.
Prerna Jain, owner of Ministry Of Cleaning suggests, 'You can use an Allen wrench to manually rotate the disposal's flywheel and free any jammed food particles.'
