Instructions

1

Try the Plunger

For sinks, plug the overflow with a wet rag. Fill the sink with 2 inches of water. Plunge vigorously for 20 strokes. Repeat 3 times before moving on.

2

Use a Drain Hook

A simple plastic drain hair removal tool can pull out clogs just below the drain cover. This solves 90% of bathroom sink and tub clogs.

3

Clean the P-Trap

Place a bucket under the P-trap. Unscrew the slip nuts by hand and remove the trap. Clean out debris and check for the clog. Reassemble and run water.

4

Use a Drain Snake

Feed the snake into the drain opening and advance by cranking the handle. When you feel resistance, continue turning to break up or pull out the clog.

5

Flush with Hot Water

Pour a full kettle of boiling water slowly into the drain. Follow with cold water. Repeat twice to flush out dissolved grease.

6

Prevent Future Clogs

Install mesh drain screens to catch hair and debris. Never pour grease down drains. Monthly hot water flushes keep drains clear.
