We did this for a project in Mexico based on the owner's Fire and Safety Rep. Directive. He was afraid that if one run-in was damaged they would have no FP for that zone. That was his only reasoning.
If someone hits one with a backhoe and they're side by side, chances are they'll hit both. So no real value there. Sometimes a secondary feed to a manifold serving several areas has been recommended by an Underwriter but the secondary feed was from another direction to minimize potential disruption due to an impairment and the manifold served up to 5 systems.

What I mean is two parallel run-ins, each with a PIV going to serve the same sprinkler riser. I have never done this before and I know FM (insured) and NFPA do not advocate this kind of arrangement. Has this ever been done before and if so why? I am trying to respond that I don't think it is a worth while investment to "ensure" continuous water supply.
