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.

Method for conducting full and empty tests on air conditioning drain piping.

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.

Method for conducting full and empty tests on water supply and hot water resin piping.

Leak testing using air pressure is now possible for water supply and hot water resin pipes (PE・PB)!

We would like to introduce the "Full and 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 by 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, the 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.

Water pressure testing method for water supply and hot water resin piping and meter unit.

Using 'Hajime-kun HWR-N1-1', we will conduct a water pressure test after the equipment installation and record the pressure!

We would like to introduce the "Water Pressure Testing Method" for water supply and hot water resin piping and meter units. 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.

Inspection methods for water supply piping at normal pressure in existing residential buildings.

Inspection of existing water supply and hot water piping can be easily carried out using our pressure recording inspection device for piping!

We would like to introduce the "Water Supply Pipe Inspection Method" for existing houses under normal water pressure. Using the pressure recording inspection device "Hajime-kun HWR-N1-1," it is easy to inspect the existing water supply and hot water pipes. By connecting the inspection device to outdoor home water faucets and stopping the shut-off valve of the water meter, you can quickly inspect the pipes by closely observing the phenomenon of water pressure dropping in case of a leak. 【Features】 - Not only can the water supply system be inspected, but the hot water side can also be checked in a single inspection. - An optional home faucet adapter is convenient when connecting to home faucets. - 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.
