3" - 6" Drain Unclogger

Drain King 750 Mechanical Drain Opener – For 3" to 6" Drain Lines

The Drain King 750 is a high-pressure water-powered drain opener designed to clear blockages in 3-inch to 6-inch drain pipes. Built for professional plumbing applications, it connects directly to a standard garden hose and uses pulsating water pressure to dislodge and flush away obstructions without chemicals or mechanical snakes.

Product Overview

Ideal for use in sewer laterals, floor drains, and other large-diameter piping systems, the 750 model expands within the pipe to form a seal and channels pulsing water to break up debris and restore flow. The tool is reusable and constructed with heavy-duty elastomer for extended service life under routine use.

• Reusable Tool: Durable construction allows for multiple uses in residential and commercial applications
• Non-Invasive: Reduces the need for cutting access points or using augers in many situations

Application Notes

Attach the Drain King 750 to a hose and insert fully into the clogged pipe. Ensure the water supply is fully open before use. The tool is designed to pulse automatically as water pressure builds and releases. Do not use in toilets or with piping smaller than 3 inches in diameter. Always follow safety guidelines and manufacturer recommendations during use.

Contractor Usage Considerations

The Drain King 750 is a practical alternative to mechanical snakes for routine maintenance or immediate blockage removal. It is especially useful in field conditions where access to powered drain cleaning equipment may be limited. Compact and portable, it’s a reliable tool for service technicians handling drain issues in commercial or residential properties.
