Large Diameter Hose
LARGE DIAMETER HOSE
All Marin County Fire Agencies are using large diameter supply hose. There is a variety of sizes and coupling styles. The Department has a number of adapters to ensure compatibility with other hose sizes and couplings.
You will also find that some agencies are using appliances at their hydrant connection, either a 4-way valve or Siamese, and some connect directly to the hydrant.
