Drains can clog for many reasons. It could be hair, soap chips, food products and oil build up. A plunger or chemical drain cleaners can be a good first step to unclogging drains. For more stubborn clogs, you can try a cable auger or plumber’s snake, a long, flexible steel cable wound around a spool that’s fitted with a hand crank. If the clogging persists after a few attempts, turn the job over to a licensed plumber. Exerting too much force can permanently damage a pipe or fixture.
