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.
