<p>PROBLEM TO BE SOLVED: To provide a piping system to which a sprinkler nozzle is easily attached by using a piping path employed for a water section equipment in a house or the like. SOLUTION: In the piping system, a branch joint part is provided for detachably attaching the sprinkler nozzle to the piping path to the water section equipment. A joint part is connected to the piping. This joint part is fitted and connected to the branch joint part. A slip preventing fitting is attached to a fitting part so that the piping does not slip in the fitting direction from the branch joint part under water pressure. Thus, piping for a sprinkler does not need to be separately provided, so that a construction load and a cost can be reduced and the branch joint part can be easily interposed in the piping path. Further, the sprinkler nozzle is detachable for maintenance and inspection.</p> |
