Abstract:
1. A method for bypassing a damaged standpipe during a fire emergency, comprising: identifying (a) the approximate location of the damage, (b) a first valve on the standpipe below the location, and (c) a second valve on the standpipe above the location, wherein the standpipe is of threaded pipe construction; shutting the water supply to the standpipe; cutting a first section out of the standpipe immediately above the first valve, thereby opening a first section of standpipe above the first valve; cutting a second section out of the standpipe immediately below the second valve, thereby opening a second section of standpipe below the second valve; capping the first and second open sections by (a) disconnecting the open sections from the first and second valves, and (b) connecting new first and second pre-prepared threaded capped pipes of the same nominal diameter as the standpipe into the first and second valves connecting a pre-determined section of flexible tubing between the first valve and the second valve; and restarting the water supply to the standpipe.
