Pipe blockage detector Unit UT661D — cable length up to 35 m, locator for clogged drains and sewers

Unit UT661D is a pipe blockage detector designed to locate clogs in drains and sewer lines. With a flexible push cable that reaches up to 35 m, the device allows technicians to feed the locator head into waste pipes and sewer runs to pinpoint the position of obstructions. The tool is intended for residential and light commercial plumbing inspections and supports targeted cleaning or repair by identifying blockages without extensive pipe excavation.

Advantages

The detector combines a long, flexible cable with a sensitive locator head to provide accurate position information for blockages inside pipes. Its cable length of up to 35 m covers most domestic and small commercial installations, while the compact design facilitates handling in tight access points. The system reduces diagnostic time by enabling direct detection of the obstruction location, improving efficiency of unclogging operations and minimizing unnecessary dismantling of pipework.

Suitable for

• Locating blockages in domestic waste pipes and sink/drain lines
• Inspecting small commercial sewer branches and building lateral drains
• Maintenance checks for partial blockages and recurrent clogs
• Pre-repair diagnostics to determine the depth and position of obstructions

Key specifications

• Cable reach: up to 35 m for insertion into drain and sewer runs
• Flexible push cable suitable for horizontal and slightly curved pipe sections
• Locator head designed for detecting mechanical blockages and debris
• Compact handheld body for one-person operation and manual feeding
• Compatibility with standard pipe diameters found in residential plumbing

How to use

Feed the flexible cable with the locator head into the drain or sewer access point until resistance indicates the suspected blockage. Use the external receiver or locating function to determine the position and depth of the obstruction from the surface. Withdraw the cable as needed to confirm the location and mark the pipe above the detected point for targeted cleaning or repair. Follow local safety procedures and isolate water flow where required before beginning work.

Usage recommendations

Operate the unit in accordance with safe working practices: wear appropriate personal protective equipment, clear access to the inspection point, and avoid forcing the cable through hard obstructions to prevent damage. For persistent or complex blockages, combine detection with appropriate mechanical cleaning tools or consult qualified plumbing services.
