Dump Site Operations #41 - Homemade Transfer Tube
President Mark Davis, April 09
From our 2012 seminar in Seneca County, NY, here are several photos showing a homemade water transfer device being used during our two-hour tanker shuttle drill. The six-inch PVC jet siphon tube was locally constructed and successfully transferred water throughout the event.

What's on Your Engine #24? - Pony Suction Fittings
President Mark Davis, April 02
A simple issue than can arise when using "pony" suction hose is that many come with 3-inch couplings which do not fit most intakes on a traditional FD pumper. These pony sections often were acquired from a portable fire pump or some type of brush/grass rig where they worked just fine. But....trying to connect a 3-inch coupling to the pumper's 2-1/2" auxiliary intake can be tricky as you work to ... (Full Story & Photos)

The hydrant was placed on the bridge over Bear Branch on Mayberry Road in Taneytown, Maryland. The installation used a 6-inch ETT Male DFH head, a 6-inch ETT stream strainer, and our ... (Full Story & Photos)

What's On Your Tanker #66 - No Frills Fills
President Mark Davis, March 12
Here are some photos from our 2010 seminar in Autauga County, Alabama, where participants observed a variety of tankers used for hauling water. Booth Volunteer Fire Department's Tanker 382, with a 1,500-gallon capacity, stood out due to its loading style. Instead of using control valves, it relied on over-the-top fill pipes for loading. This approach was typical for vehicles from that era in southern ... (Full Story & Photos)

What's On Your Engine #23? - LDH But No LDH Discharge
President Mark Davis, March 05
While going through photos from our 2011 seminar in Dekalb County, Alabama, we found several images demonstrating how to use 5-inch large-diameter hose (LDH) when your pumper does not have an LDH discharge. This is not a new technique, but these photos serve as a useful reminder.
By connecting two smaller hoses from a pair of 2-1/2 inch discharges into an LDH appliance, flow is typically improved ... (Full Story & Photos)
