Terms for this evolution.
- LDH - Large Diameter Hose, generally 5" in diameter.
- Stortz fitting - Non-Gendered fitting normally on LDH hose.
- Higby Notch - notch in the male threaded coupling which enables easier assembly.
- Gate Valve - Device that contains a shutoff and it allows a 2 1/2" hose to be connected without shutting down the hydrant.
- Dry Hydrant - Used in cold climates, the hydrant drains out water below ground level
- Spanner - A C-shaped wrench used to couple,loosen hose fittings
Preparation
Inspect the hosebed and hydrant bag on the apparatus. Become familiar with the setup and whats available. At minimum, there should be a hydrant wrench, spanner, and 2 1/2" gate valve. There should also be an adapter on the end of the 5" hose to go from Storz to a 4" female fitting.

Detail
After the engine comes to a complete stop, pull the 5" LDH off the bed along with the connected hydrant bag. The hydrant bag contains the 2 1/2" gate valve, hydrant wrench, 5"storz to 4" female adapter, and break away strap. Pull the hose past the hydrant approx 6 feet. If you have a break away strap, loop it over the hydrant and signal the driver to proceed. The alternative is to wrap the hose around the hydrant twice, and place your foot on the end of fitting. Be careful not to be in any position to get pinched between the hydrant and the hose since the hose may get taught. Signal the driver to proceed. After 200' (2 lengths of hose) deploy, remove the 5" and 2 1/2" steamer fittings (caps) off the hydrant. Open the hydrant with a hydrant wrench a few turns till water flows. This flushes out any debris. Note: the bolt on the top of the hydrant is labelled with which direction to turn. Close the hydrant. Uncoil the hose and thread the connection on to the steamer male threads. Connect the 2 1/2" gate valve to the hydrant. Radio to the driver the hydrant is connected and awaiting orders to open the hydrant. Open the hydrant all the way, if not water will run out the bleeder hole at the base of the hydrant and after time will erode the backfill around the hydrant. Straighen out any kinks in the hose.
