Study Notes
Fire Hydrants and Pumps
- Dry barrel hydrants are used in areas where the temperature may drop below freezing.
- Wet barrel hydrants are used in areas where temperatures remain above freezing.
Hydrostatic Pressure Test
- The purpose of the hydrostatic pressure test of the pump casing is to ensure the pump can withstand twice the maximum design working pressure.
- The minimum duration for maintaining twice the maximum design working pressure during the hydrostatic pressure test is not specified.
Annual Testing of Fire Pumps
- The purpose of the annual capacity testing of fire pumps is to ensure the pump can meet its rated capacity.
- The minimum requirement for testing fire pumps annually is not specified.
- The test line on the pump discharge is used during annual testing to measure the pump's capacity.
Detecting and Thawing Frozen Hydrants
- The recommended method for detecting freezing in hydrants is to use a pressure gauge or thermometer.
- The recommended method for thawing a frozen hydrant is not specified.
Dry Barrel Hydrants
- The drain valve at the base of the barrel in the dry barrel hydrant is used to drain water from the hydrant to prevent freezing.
Purpose of Annual Testing
- The purpose of the annual testing of fire pumps is to ensure the pump is functioning properly and can meet its rated capacity.
- The annual testing of fire pumps is NOT used to determine the pump's flow rate.
