The stainless steel temporary piping system REPCS is a rental service for temporary piping that can be utilized for the relocation of water pipes during water supply pipe renewal work and sewer pipe renewal work without requiring a water outage, ensuring a "safe and secure" water supply. It allows for the rental of the necessary amount for the required period during water and sewage construction work and restoration work during disasters, making it environmentally friendly and economically advantageous. In times of disaster, we leverage our past experiences to provide rapid water supply to affected areas and contribute to the restoration of water pipes after disasters. Additionally, we use our patented Grooved Joint System, which allows for easy pipe connections by simply inserting and twisting, making it easy for anyone to install. We offer a "G type" for quick installation in three steps and a standard "H type." This service, uniquely devised by our company, started in 1989 and is now adopted by over 85% of municipalities nationwide, from Hokkaido to Kyushu. 【Five Key Points】 ■ Easy joining ■ Built-in disengagement prevention mechanism ■ Excellent pressure resistance ■ Reliable safety ■ Smooth shipping response for peace of mind at any time
