A Siamese connection needs a professional designer with meticulous attention to detail to ensure that it does not inconvenience firefighters when connecting hoses to it. The thread must be compatible with the hoses. The common size of the female inlets is 2 ½ inches with 3 inches also used in some states. Our engineers will enquire from your local fire department that which size they are using for their hoses so that we can design the inlet accordingly.
Because the design is exposed, it has to be weather resistant. We check that in our designs to ensure that our design materials last long. Also, it is highly likely for grime to clog the waterways when the equipment is not fully covered. We have plugs to cover the inlets and are easily removable by the fire department when it is time to refill your system.
When it’s time to install the connection, we take into account code recommendations with regard to locations. Installing Siamese connection is a demanding task that needs professional engineers who understand the network of the sprinkler system or standpipes in your building. The connection must be efficiently connected to the current system to supply enough supplemental water. There is no doubt that our engineers will excel in that. We have installed plenty of fire department connections throughout Chicago and New York.
In addition to the design and installation of this connection, you have to consider the inspection, testing, and maintenance of this connection. NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems gives guidelines about a periodic inspection, testing, and maintenance of fire sprinklers, standpipes and other systems including fire department connections. We will take note of this standard when inspecting, testing and maintaining this connection.
