“In essence, cold-water plumbing fixtures are fed directly from the sprinkler piping,” he says. PEX pipe can be installed in multipurpose, passive purge or stand-alone systems, but typically our AquaSAFE system is installed as a loop. “The other major benefit is the flexible installation options. “All of the benefits that PEX has over other materials in plumbing and radiant heating/cooling also apply to our AquaSAFE PEX-based fire sprinkler system,” Skare says. Most AquaSAFE systems use a loop of 3/4- or 1-inch PEX with 1 1/4-inch available for challenging water supply applications. The PEX multipurpose system uses about half the fittings and connections of a comparable CPVC system and eliminates stagnant water, as well as the need for check valves, backflow preventers and the maintenance and inspections required by stand-alone fire safety systems. “If it’s a large-scale remodel with open access to the ceiling and the walls, it’s much easier, but the beauty in remodels is the flexible nature of our piping product.” “It can be used in remodel applications, but it’s a bit more difficult,” he says.

Heads are recessed or concealed behind a plate to blend with home décor. Each sprinkler is individually heat activated. The AquaSAFE sprinkler system integrates with the home’s cold-water plumbing, ensuring freshwater is always available in the event of a fire. “A home that’s engineered with I-joists or open-web floor trusses would typically need to be protected by Sheetrock or some other type of fire barrier, unless fire sprinklers are installed.”
