A method of installing sprinkler-head mounting pipes for supply of water to sprinkler head mounting pipes for supply of water to sprinkler heads employed for release of water for extinguishing fires, as well as piping arrangements for sprinkler head mounting, are provided herein. In the piping arrangement the joints each have at least two outlet ports. The sprinkler heads are coupled to the outlet ports via flexible pipes. As a consequence, the piping arrangement as a whole is simplified and the required series of piping operations can be easily carried out.
