Can the Hose Monster be used on a roof-top standpipe test?
A. Yes. In fact, a roof-top standpipe test should not be conducted without a Hose Monster. With the Hose Monster, a roof-top flow test can be conducted any time of day because no water is disbursed over the side of the building. The 2 1/2″ Hose Monster with a UL Nozzle Insert is commonly used and can lie directly on the roof without causing damage. 500 GPM = 2 ½” Hose Monster with 1 ¾” Nozzle Insert 250 GPM = 2 ½” Hose Monster with 1 1/8″ Nozzle Insert See the video of the Hose Monster® on a roof-top in Wilmette Illinois.
