Drainage pipe filling and emptying test method

Traditionally, water filling and full water tests have been conducted on drainage pipes, but testing is now possible with air pressure!

We would like to introduce the "Full and 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 fixtures that correspond to the full and empty test on each floor. - If full and empty compatible joints and fixtures cannot be used, employ balloon-type fixtures (such as test plugs). - For the terminal ends of horizontal pipes, various sealing fixtures 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.
