Temporary Piping Material Rentals

Working toward a Greener Environment and a Better Society

Temporarily rented piping material

●Reuse rental program
Typically, once a project with temporary piping is complete on a worksite, the piping material is disposed of, and new material is used for the next project, without considering the effect on the environment.
The first company in Ikuno Ward, Osaka to receive ISO 14001 certification (2000) for its environmental management system and certified for ISO 9001 as well (1998), Komei Manufacturing developed its reuse rental program to decrease the burden of piping on the environment while encouraging recycling.

With reuse, pipes and related items are supplied to worksites. Because Komei Manufacturing is an expert in piping, it ensures that its rental products can be used safely to supply water and eliminating the issues of disposal.Its clients save material and labor as well as finding their construction process is faster, decreasing costs and contributing to the environment.

●Repurchase program
Another innovative way Komei Manufacturing is contributing to industry is through its Repurchase program, providing water supply materials that assist projects in progressing more smoothly from material procurement to project completion.

Multi-functional Water Shutoff Valves


1. Capable of stepless flow volume control, a feature not possible with conventional check valves.
2. The ball-type auxiliary valve allows easy replacement of rubber gaskets.
3. The lift-type check valve with a built-in spring ensures normal operation even at 90 degrees, providing support in case the pipe is twisted or falls.
4. The handle can be removed to prevent water theft.
5. The top handle screw can be loosened to remove air in the pipe and water meter, and a pressure gauge can be fitted at the stop screw to record pressure changes when the handle lever is turned off.
6. The expandable shutoff valve construction simplifies water meter replacement.
7. False reading of the water meter indicator due to pressure pulsation in the main can be prevented
