Traditionally, water filling and full water tests have been conducted on drainage pipes, but now testing is possible with air pressure!
We would like to introduce the "Full/Empty Test Method" for drainage pipes. By using the pressure recording inspection device "Hajime-kun HWR-N1-1," it is now possible to conduct tests on drainage pipes that have traditionally undergone water filling and full water tests using air pressure. Even in cases of defects, this non-wetting test does not require the arrangement of water or drainage, making it suitable for processes where these are not prepared. 【Inspection Preparation (Excerpt)】 ■ For vertical pipes, use full water joints and testing tools that correspond to the full/empty test on each floor. ■ If full/empty compatible joints or tools cannot be used, employ balloon-type tools (such as test plugs). ■ For the terminal ends of horizontal pipes, sealing tools (various types) can be used, and caps can be glued on and cut after inspection. ■ Simply inserting a PVC pipe into the joint of a horizontal pipe for inspection may not leak water, but there have been cases where air leaks, so always conduct the inspection after gluing. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Inspection Preparations】 ■ For fixtures such as unit baths, washing machine pans, and toilets, there are types that are difficult to seal, so either conduct the inspection without connecting the fixtures or inquire with the manufacturer about conducting a pneumatic pressure test at around 35 kPa. ■ For connecting to the inspection device, using the connection port of the pneumatic test jig improves work efficiency, and it is also possible at the fixture attachment points. *For more details, please refer to the PDF materials or feel free to contact us.
