*when used regularly

1. Open
Carefully push down on childproof cap with palm of hand and turn cap counterclockwise. Don't squeeze bottle or splash product. (Clean up any spills at once.) To lock cap, push down on cap and screw on tightly.

2. Flush
For slow-running drain, run warm water (not hot) through drain for one minute.

3. Pour
For slow drains: turn off water and pour half of a 30oz bottle directly into drain. Briefly run water again (approximately two cups) to activate and distribute formula along pipe walls.
For regular maintenance: pour 2 ounces down each drain or 4 ounces down each toilet every 2-4 weeks

• Initial use may cause loosened build-up to temporarily slow or in rare cases block the flow of water.
• Do not worry—this means that the product is working to remove build-up.
• If this occurs, plunge and repeat the treatment.
• Avoid using other drain openers during this time.
