The air conditioning drain pipe's full and empty test can be conducted! In the case of pneumatic pressure, one-person operation is possible, contributing to a reduction in the burden on the site.
We would like to introduce the "Full and Empty Test Method" for air conditioning drain piping. By using the pressure recording inspection device "Hajime-kun HWR-N1-1" for piping, the full and empty test for air conditioning drain piping can be conducted. Compared to traditional water flow or water filling tests, this method does not wet the piping, allowing for time savings and easy data management due to the automatic pressure data recording function. For pipes within the specified capacity, the pass/fail judgment function is effective, and in the case of air pressure, one-person operation is possible, contributing to a reduction in the burden on site. 【Inspection Preparation (Excerpt)】 - For vertical pipes, use full and empty fittings and sealing jigs suitable for the full and empty test on each floor. - If full and empty compatible fittings and jigs cannot be used, balloon-type jigs (such as test plugs) may also be used. Choosing ones that are easy to attach and detach will improve work efficiency. - Various sealing jigs can be used at the hose terminal from the horizontal pipe, and caps can be glued and cut after inspection. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Inspection Preparations】 - In inspections where a PVC pipe is simply inserted into the joint of the lateral pipe, there have been cases where air leaks even if water does not, so always conduct the inspection after adhesion. - Depending on the type of drain hose, it may not be suitable for air pressure testing, so please inquire with the manufacturer about the applicability of air pressure testing (35 kPa pressurization). - For better workability, connect the inspection device to the end of the drain hose or conduct the inspection from the connection port of the jig. *For more details, please refer to the PDF document or feel free to contact us.
