The answer to 'types of drain cleaning' is that there are several common methods for clearing clogged drains in the home. The most common are using a plunger, a drain snake or auger, chemical drain cleaners, and hydro-jetting.
Plungers use suction to dislodge and remove clogs from sinks, showers, and tubs. Drain snakes or augers are long, flexible metal cables that can be fed down the drain to physically break up and remove blockages. Chemical drain cleaners use harsh acids or solvents to dissolve organic matter causing the clog. Hydro-jetting uses high-pressure water to flush out built-up debris and grease from pipes.
