Fire Sprinkler Tank Sizing

Always contact your fire chief and local public building officials before moving ahead with a storage tank project involving fire sprinklers or hydrants.

Fire sprinkler tank sizing.

If a residential home water system doesn t meet the psi needs of the fire sprinkler system called fire flow a water storage solution may be needed to obtain a building permit. Pumps must maintain a positive suction pressure at the suction flange. The fire department drafting connections are made through bulkhead fittings in the tank wall and then buried underground until they exit at the desired drafting location. Calculate minimum flow from the mrh with the sprinkler minimum pressure and k factor.

Improper tank size location or plumbing layout may reduce the effectiveness of the water supply creating liability and possible occupancy issues. Water levels are critical for fire sprinkler systems. This standard provides the minimum requirements for the design construction installation and maintenance of tanks and accessory equipment that supply. Electrical feeds to fire pump controllers must have a two hour fire rating.

Most fire departments approve fiberglass water tanks for fire protection systems. Underground fiberglass fire protection tanks are kept out of visible sight consume less property and provide more security from external factors. Horizontal elbows or tees upstream of a fire pump must be 10 pipe diameters from the suction flange on a split case fire pump. Sprinkler calculation step by step.

Tanks must be sized to provide enough water to control or suppress a fire in the building and water levels must be checked and maintained. Calculate the minimum flow given the system design density and sprinkler head area.
