1" - 2" Drain Unclogger

Drain King 501 Water-Powered Drain Opener – 1" to 2" Pipe Range

The Drain King 501 is a water-inflated drain cleaning tool designed for clearing blockages in 1-inch to 2-inch diameter drain lines. When connected to a standard garden hose, the tool expands to seal inside the pipe and delivers pulsating water pressure to break up clogs caused by grease, hair, sediment, or soap buildup. This non-chemical method is commonly used in sinks, showers, and laundry drain applications.

Product Features

• Compatible Pipe Sizes: 1" to 2" inside diameter
• Operation: Connects to a garden hose; inflates to form a water-tight seal and releases pulsating jets to dislodge obstructions
• Material: Heavy-duty rubber body with integral internal valve assembly
• Connection Type: Standard 3/4" hose thread (GHT)
• Reusability: Designed for repeated use under normal job site conditions

Installation and Use

Attach the Drain King 501 to a garden hose and insert it fully into the clogged drain line. As water is introduced, the tool inflates and discharges pressurized pulses downstream to dislodge and flush out obstructions. Always monitor usage to avoid over-pressurizing older or fragile piping. This tool is suitable for use on residential branch lines made of copper, ABS, PVC, or cast iron.

Contractor Considerations

• No Chemical Exposure: Eliminates the need for caustic drain cleaners that can damage plumbing systems over time
• Reusable Design: Reliable performance across multiple jobs without the need for replacement parts
• Time-Saving: Quickly clears soft or semi-solid obstructions in residential lateral runs without requiring disassembly of plumbing

Technical Notes

• Minimum Water Pressure: 40 PSI recommended for effective operation
• Do Not Use On: Toilets or vent stacks – product is not designed to pass through toilet trapways or vertical-only lines
• Safe Use: Use only with cold water; ensure full insertion into drain to prevent backflow at activation
