1) If a drain is simply moving slowly, a clog may be starting to form or the vent system may be blocked. You can use a chemical drain cleaner to open a slow-moving drain, but beware—the caustic nature of most drain cleaners can damage certain kinds of pipes and upset the delicate chemical balance of a septic system. And if the drain becomes fully clogged, the caustic solution can back up into a fixture, making it hazardous to plunge the drain.

2) Plunge the drain at the fixture.

3) Try to clear out a hair blockage in a sink or tub drain with the help of a straightened coat hanger with a small hook at one end). Remove and clean the pop-up as hair and debris often collect around this assembly.

4) Connect a hydraulic bladder to a garden hose and try blasting out the clog.

5) Try to clear the blockage with a snake, working from the fixture.

6) Try to clear the blockage with a snake, working from a branch cleanout.

7) If all else fails, call in a plumber.

A Safety Tip: Use chemical drain cleaners sparingly. Some products are alkalis that cut grease, others are acids that dissolve clogs. They cannot only damage your pipes but also can be hard on the environment. Use them only in a well-ventilated room, and never use the plunger and chemicals in combination as even diluted chemicals splashed on you could burn you. Wear rubber gloves, eye protection, and be sure to read the label and follow directions carefully.
