The Uponor AquaSAFE multipurpose residential fire sprinkler system integrates the fire sprinkler system with a home’s cold-water plumbing. It is easy to install because it uses the same tubing, fittings and tools as an Uponor plumbing system. Plus, it offers homeowners added peace of mind because it ensures fresh water is available to the sprinklers each time an occupant uses a cold-water plumbing fixture. It uses the same flexible, durable crosslinked polyethylene (PEX-a) tubing that has been used for more than two decades in plumbing systems around the world.
