Removal of a Water-Flow Switch

Q: We have a water-flow switch on the line that rises through a nursing wing stairwell and feeds the hose cabinets. There are no longer any hoses in the cabinets. Can we remove the flow switch? I don’t know if it’s relevant but our pump test manifold is also on this riser.  I am going on the fact that if the fire department hooks up to the hose riser hopefully we will know there is a fire!

A: I do not believe you are permitted to remove the waterflow alarm switches from the standpipes, and you still need to maintain them and test them. According to NFPA 14 (standard for the installation of standpipes), 2010 edition, says you must have waterflow alarms on standpipes required by the AHJ. The presumption here is the installation of the standpipe was required by some AHJ, or they would not have been installed. In hospitals, only high-rise buildings are required to have standpipe system, so if your facility qualifies as a high-rise, then I would say no. If you want to pursue this issue, you would need to have written approval from all the AHJs who govern your hospital, such as CMS, Joint Commission, the local AHJ, the state AHJ, and the insurance company. Not likely that they would all agree to let you remove the devices.
