In this episode of Moving Water, Chris Mc Loone, Andy Soccodato, and Bill Adkins discuss preventive maintenance on water delivery equipment. From manifold appliances and nozzles to intake valves and tanker dump valves, the conversation lays out practical advice for keeping your apparatus fully operational. Here are some insights.
Saccedato emphasizes how vital it is to “exercise” valves—both internal and external intake valves—by routinely opening and closing them. This simple step prevents them from freezing or sticking due to lack of use. Many departments allow reserve rigs or seldom-used units to sit without functioning these critical components, which leads to stubborn, unreliable valves on the next call.
Nozzles also deserve attention. Soccodato says, “Regular maintenance should involve cleaning nozzles in soapy water, exercising the bales, and lubricating moving parts at least monthly. For combination fog nozzles exposed on bumpers or tailboards, this upkeep prevents clogs from road grime or debris. Adkins adds that training on proper disassembly and reassembly is essential; improper handling can cause operational failures at critical moments.
For tanker crews, the maintenance spectrum extends to dump valves. They caution that, in modern rigs using pneumatic or electric systems to operate dump chutes, regular exercising of these systems is even more critical. Failure to keep these components operational can leave a tanker unable to offload vital water supply during an incident, significantly hampering scene operations.
One of the lesser-known tips shared on the podcast concerns “front flushing” your pump. Unlike the common practice of back flushing, front flushing involves capping off discharges and pre-connects, then opening the tank-to-pump valve and discharge valve along with the drain valve to force water through the drain tubes and valves.
