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 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.
