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.

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, it is possible to conduct full and empty tests on air conditioning drain piping. 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 piping within the specified capacity, the pass/fail judgment function is effective. Additionally, in the case of air pressure, one-person operation is possible, contributing to a reduction in the burden on the 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. - For the hose terminal from the horizontal pipe, various sealing jigs can be used, and caps can be glued and cut after inspection. *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Full/Empty Test Method" for water supply and hot water resin piping. By using the pressure recording inspection device "Hajime-kun HWR-N1-1," it is possible to conduct leak tests on water supply and hot water resin piping (PE, PB) using air pressure. For piping concealed behind walls or flooring, such as in cases of nail penetration accidents or when defective areas are located at heights or angles that are difficult to visually inspect, our air pressure testing method can effectively address even minor leaks that are hard to detect. 【Inspection Options】 ■ HWR-OP01 ■ HWR-OP02 ■ HWR-OP03 *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "Water Pressure Testing Method" from the water supply and hot water resin piping and meter unit. Using the pressure recording tester "Hajime-kun HWR-N1-1" for piping, water pressure tests can be conducted after installing fixtures such as faucets, and pressure records can be obtained. Please feel free to contact us when you need assistance. 【Features】 ■ To bypass the water supply and hot water circuits, using a "ball valve with a check valve release function" on the water heater allows for convenient release only during testing. ■ When applying water pressure from the meter unit, the method for releasing the unit's check valve varies by manufacturer, so confirmation is necessary. ■ If you want to apply water pressure to multiple rooms in advance, we recommend the optional O-ring adapter + ball valve (HWR-OP11). *For more details, please refer to the PDF document or feel free to contact us.

• Measurement and Inspection

We would like to introduce the "Water Supply Pipe Inspection Method" for existing residential buildings under normal water pressure. Using the pipe pressure recording inspection device "Hajime-kun HWR-N1-1," it is easy to inspect existing water supply and hot water pipes. By connecting the inspection device to outdoor home water faucets, stopping the shut-off valve of the water meter, and closely observing the phenomenon of water pressure dropping in case of a leak, the inspection of the pipes can be completed in a short time. 【Features】 - Not only can the water supply system be inspected, but the hot water side can also be inspected in one go. - When connecting to a home water faucet, the optional home water faucet adapter is convenient. - Since the general faucet cartridge has a check valve function, it is advisable to use a fixed cartridge for inspection. - It can be used to inspect old pipes before making modifications to the equipment during renovations. *For more details, please refer to the PDF document or feel free to contact us.

Replacing the gauge-type pressure gauge allows for smoother recording and management of pressure test data. Equipped with a color LCD touch panel, you can check pressure graphs in real-time. We have prepared a wide range of pressure sensors according to the pressure range you wish to measure. You can use sensors tailored to the target pressure for applications such as vacuum measurement, drainage, testing of water supply and hot water piping, and pressure testing of air conditioning refrigerant gas. The measured data can be saved to the included USB memory and managed with software for PC (Windows), allowing you to print management reports. With a built-in lithium-ion battery, it can operate for over 10 hours. For extended continuous use, please use an AC100V power supply. The report software for Windows can be downloaded after user registration. The connection to the inspected piping is made using the included piping connection adapter, connected with G1/2 threads. Please prepare a pressurization device (such as an air compressor or test pump) separately. *For more details, please refer to the PDF materials or feel free to contact us.

Replacing the analog pressure gauge allows for efficient recording and management of pressure test data. Equipped with various leak inspection menus developed through the Bikkurikun series, it enables quick leak detection without pressurizing while maintaining water supply pressure. It also supports pressure testing and leak inspection for air conditioning drain pipes and drainage pipes within specified capacity ranges. It accommodates pressure tests according to manufacturer and company rules in an optional judgment mode, recording temperature along with arbitrary pressure standards (final pressure, pressure difference %, pressure difference kPa) for up to 24 hours, with pass/fail indication available. In addition to storing up to 20 data entries in the main unit, data can be managed via Bluetooth connection with an iPhone or iPad, and management reports can be printed using software for PC (Windows). The device operates for over 24 hours on four AA batteries or nickel-metal hydride rechargeable batteries. A dedicated app for iOS (free) is available from the App Store. The report software for Windows can be downloaded after user registration. To connect to the inspected piping, use the included O-ring adapter with your fittings and connect using G1/2 threads. Please prepare a separate pressurization device (air compressor, test pump, etc.).
