The system includes a tank for storing fire protection system water, a hose connecting the building fire protection system to the tank. A vacuum pump is configured to draw a low pressure on the fire protection system. A water pump is configured to return the water of the fire protection system from the tank to the system. ## Claims ### Claim 1 A portable fluid storage system for draining and re-filling a building fire protection system comprising: a fluid tank; a hose connected to the fluid tank at a first end, and having a second end connectable to the building fire protection system; a fluid pump positioned along a flow path of the hose, wherein upon an activation of the fluid pump, is configured to pump a quantity of fluid from the fluid tank, through the hose, to the building fire protection system; and a vacuum pump positioned along the flow path of the hose, wherein upon activation of the vacuum pump, is configured to draw a negative pressure on the hose second end to convey a fluid through the hose into the fluid tank. ### Claim 2 (depends on 1) The portable fluid storage system of claim 1 wherein the fluid tank, hose, fluid pump, and vacuum pump are all connected to a vehicle trailer. ### Claim 3 (depends on 1) The portable fluid storage system of claim 1 wherein the fire protection system is a wet pipe sprinkler system. ### Claim 4 (depends on 1) The portable fluid storage system of claim 1 further comprising a valve positioned near the first end of the hose, the valve capable of providing an inlet flow to the tank in a first position of the tank in a first valve position, and an outlet flow from the tank from a bottom of the tank in a second valve position. ### Claim 5 (depends on 1) The portable fluid storage system of claim 1 further comprising a plurality of tanks. ### Claim 6 (depends on 1) The portable fluid storage system of claim 1 further comprising a hose reel, the hose wrappable about the hose reel. ### Claim 7 (depends on 1) The portable fluid storage system of claim 1 further comprising an isolation valve along the hose between the vacuum pump and the tank. ### Claim 8 (depends on 1) The portable fluid storage system of claim 1 wherein the hose second end is connected to a drain port of the building fire protection system. ### Claim 9 (depends on 1) The portable fluid storage system of claim 1 further comprising a generator configured to power at least one of the fluid pump and the vacuum pump. ### Claim 10 (depends on 1) The portable fluid storage system of claim 1 wherein the vacuum pump is configured to be continuously operated after a draining of the building fire protection system into the tank. ### Claim 11 A fluid storage system connected to a building fire protection system, the fluid storage system comprising: a fluid tank; a hose connected to the fluid tank at a first end, and having a second end connectable to the building fire protection system; a fluid pump positioned along a flow path of the hose, wherein upon an activation of the fluid pump, is configured to pump a quantity of fluid from the fluid tank, through the hose, to the building fire protection system; and a vacuum pump positioned along the flow path of the hose, wherein upon activation of the vacuum pump, is configured to draw a negative pressure on the hose second end to convey a fluid through the hose into the fluid tank; the building fire protection system comprising: a quantity of piping; at least one sprinkler head; and a drain port, wherein the hose second end is connected to the drain port. ### Claim 12 (depends on 11) The portable fluid storage system of claim 11 wherein the fluid tank, hose, fluid pump, and vacuum pump are all connected to a vehicle trailer. ### Claim 13 (depends on 11) The portable fluid storage system of claim 11 wherein the fire protection system is a wet pipe sprinkler system. ### Claim 14 (depends on 11) The portable fluid storage system of claim 11 further comprising a valve positioned near the first end of the hose, the valve capable of providing an inlet flow to the tank in a first position of the tank in a first valve position, and an outlet flow from the tank from a bottom of the tank in a second valve position. ### Claim 15 (depends on 11) The portable fluid storage system of claim 11 further comprising a plurality of tanks. ### Claim 16 (depends on 11) The portable fluid storage system of claim 11 further comprising a hose reel, the hose wrappable about the hose reel. ### Claim 17 (depends on 11) The portable fluid storage system of claim 11 further comprising an isolation valve along the hose between the vacuum pump and the tank. ### Claim 18 (depends on 11) The portable fluid storage system of claim 11 further comprising a secondary fluid pump configured to pump fluid into the fire protection system through the hose. ### Claim 19 (depends on 11) The portable fluid storage system of claim 11 further comprising a generator configured to power the fluid pump and the vacuum pump. ### Claim 20 (depends on 11) The portable fluid storage system of claim 11 wherein the vacuum pump is configured to be continuously operated after a draining of the building fire protection system into the tank.
