The Uponor fire safety system is actually incorporated into your Uponor PEX Plumbing System. It uses the same Wirsbo AQUAPEX® tubing that provides water to the plumbing fixtures in your home so there is always a ready supply of water to the sprinkler heads
A dedicated manifold feeds ½" Wirsbo AQUAPEX tubing directly to a special fitting equipped with four outlets. This fitting is attached to the sprinkler head. The remaining three ports on the fitting are then used to feed other sprinklers or plumbing fixtures.
The result is an interconnected grid of plumbing fixtures and sprinklers. The combination system reduces cost and ensures reliability. The system also eliminates stagnant water because the same lines that are used to feed your sprinklers are used to feed your facets, showers and toilets. As long as you have water supplied to your plumbing fixtures, you know you have water supplied to your sprinklers.
