When challenged by an AHJ for using riser manifolds with the flow switch inches from the Tets & Drain valve I contacted the manufacturer (either Potter or System Sensor I cannot remember which one) and was told there was a 2' RECOMMENDATION but was not a requirement and as such did not violate the listing. This was several years ago however. Greg

Just what I was told once, notta clue if it's a valid concern _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum
