The "WSATB" is a testing device that uses our wastewater pipe sealing plug, "Sealing Ball," allowing for airtightness (presence of damage) testing within pipes. Test data is transmitted to a tablet device, enabling real-time observation of not only the results but also pass/fail judgments during the test and internal pipe pressure. After the test is completed, a report for submission can also be generated. 【Features】 ■ Real-time display of measurement progress on the tablet ■ Settings for acclimatization time, measurement time, and allowable pressure drop range can be adjusted according to inspection standards ■ Titles can be freely set for submission materials for airtightness tests and pressure tests ■ Compatible with pipe diameters ranging from 100 to 1800 mm *For more details, please contact us or download the PDF.

The "Stop Water Ball Short Type" is a device that uses a stop water ball tailored to the pipe diameter, designed for temporary water stoppage during tasks such as cleaning, dredging, various inspections, tests, and repairs within the pipe. It expands by injecting air using a foot pump or compressor, creating a tight seal against the pipe's interior to stop the water flow. Additionally, the version with a bypass can be used for various tests such as pressure tests and water-tight tests, as well as for water replacement work. It is available in a total of 10 types: 5 sizes without a bypass and 5 sizes with a bypass, suitable for pipe diameters ranging from 75 to 300 mm. For more details, please contact us or refer to the catalog.

The bypass-free version can be bent up to 90° while deflated, making it suitable for installation in small-diameter manholes. The version with a bypass can be used for various tests such as pressure tests and water-tightness tests, as well as for water replacement work. It expands by injecting air using a foot pump or compressor, adhering tightly to the inside of the pipe to stop water flow. For more details, please contact us or refer to the catalog.

The "Stop Water Ball Large Flow Drainage Type" is suitable for water replacement work that requires the passage of large flow drainage through a large bypass section. It is reinforced with high-quality Kevlar fibers, offering excellent elasticity and compatibility with various pipe diameters. Additionally, the drainage flange ring can be replaced according to the actual flow rate. The material is SBR synthetic rubber (styrene-butadiene rubber) reinforced with Kevlar fibers. For more details, please contact us or refer to the catalog.
