The apparatus also includes a chemical storage assembly. The chemical storage assembly is coupled to at least one outlet of the intake assembly. The chemical storage assembly is configured for at least one of (a) storing a chemical or (b) mixing a chemical with a liquid from the pressurized liquid source. The apparatus further includes an outlet assembly. The outlet assembly includes a first outlet configured for expelling pressurized liquid from the pressurized liquid source in a first direction. The outlet assembly also includes a second outlet or a nozzle for expelling the chemical, the chemical mixed with the liquid, a chemical agent, or a foam mixture in a second direction. ## Claims ### Claim 1 An apparatus comprising: an intake assembly, the intake assembly including a connector and an excess flow valve, the connector configured for coupling to a pressurized liquid source, the pressurized liquid source supplying a pressurized liquid to the intake assembly, the excess flow valve in fluid communication with a first flow valve outlet and a second flow valve outlet to direct the pressurized liquid from the intake assembly to one or more assemblies upon application of a first pressure or a second pressure; an outlet assembly, the outlet assembly being coupled to the first flow valve outlet of the intake assembly to receive pressurized liquid from the first flow valve outlet upon application of the first pressure, the outlet assembly including a first outlet configured for expelling pressurized liquid from the pressurized liquid source in a first direction, the outlet assembly including a second outlet configured for expelling at least one of a chemical or a chemical mixed with a liquid in a second direction; and a chemical storage assembly, the chemical storage assembly being coupled to the second flow valve outlet of the intake assembly to receive pressurized liquid from the second flow valve outlet upon application of the second pressure, the first pressure being higher than the second pressure, the chemical storage assembly being configured for at least one of (a) storing the chemical or (b) mixing the chemical with the liquid from the pressurized liquid source. ### Claim 2 (depends on 1) The apparatus of claim 1, further including: a permeable metering hose disposed within the chemical storage assembly, the permeable metering hose coupled with the second flow valve outlet; and a fluid line coupled between the intake assembly and the outlet assembly, the fluid line configured to transfer fluid from the first flow valve outlet to the outlet assembly. ### Claim 3 (depends on 2) The apparatus of claim 2, further including: a check valve coupled between the fluid line and the outlet assembly, the check valve configured to direct fluid at the first pressure to the outlet assembly and configured to prevent fluid at the second pressure from entering the outlet assembly. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the first outlet of the outlet assembly includes a plurality of nozzles configured for expelling pressurized liquid from the pressurized liquid source. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein each one of the plurality of nozzles defines an orifice having a diameter sized at least as large as the other ones of the plurality of nozzles. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the second outlet of the outlet assembly is a chemical agent nozzle, the chemical agent nozzle coupled to an eccentrically-weighted nozzle head. ### Claim 7 (depends on 1) The apparatus of claim 1, further including: a fill tube assembly including at least one inlet port configured for receiving the chemical agent, the fill tube assembly configured for receiving the chemical agent into the apparatus. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the fill tube assembly and the outlet assembly are each configured for removable coupling to an outlet end connector via the bayonet locking system, the outlet end connector configured for coupling between the chemical storage assembly and at least one of the fill tube assembly and the outlet assembly. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the bayonet locking system comprises the outlet end connector including a bayonet connection end and each of the fill tube assembly and the outlet assembly including a bayonet plate configured to mate with the bayonet connection end of the outlet end connector. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the first direction is orthogonal to the second direction.
