A chemical sprayer system includes a three-way valve that includes an inlet port coupled to a fluid source, a first outlet port in fluid communication with a first elongated fluid passage, a second outlet port in fluid communication with a second elongated fluid passage, and a control. The control allows a user to place the three-way valve into one of a first ON state in which the first outlet port is in fluid communication with the inlet port, a second ON state in which the second outlet port is in fluid communication with the inlet port, and an OFF state in which substantially no fluid is allowed to exit the inlet port. The first elongated fluid passage terminates in a nozzle adapted for spraying foam. The second elongated fluid passage terminates in a nozzle adapted for spraying liquids.

What is claimed is: 1. A chemical sprayer system, comprising: a. a three-way valve including an inlet port, that is capable of being coupled to a fluid source, a first outlet port, a second outlet port, and a three-state control that allows a user to place the three-way valve into one of a plurality of states, including: a first ON state in which the first outlet port is in fluid communication with the inlet port, a second ON state in which the second outlet port is in fluid communication with the inlet port, and an OFF state in which substantially no fluid is allowed to exit the inlet port to either the first outlet port or the second outlet port; b. a first elongated fluid passage having a first proximal end and an opposite first distal end, the first proximal end in fluid communication with the first outlet port, the first distal end terminating in a first nozzle, the first nozzle adapted for spraying foam; c. a second elongated fluid passage, spaced apart from and substantially parallel to the first elongated fluid passage, having a second proximal end and an opposite second distal end, the second proximal end in fluid communication with the second outlet port, the second distal end terminating in a second nozzle, the second nozzle adapted for spraying liquid phase fluids: d. a first parallel portion, spaced apart from the second elongated fluid passage at a first distance; e. a second parallel portion, spaced apart from the second elongated fluid passage at a second distance, the second distance being less than the first distance; and f. a transverse portion connecting the first parallel portion to the second parallel portion. 2. The chemical sprayer of claim 1, further comprising a connecting passage that couples the first proximal end of the first elongated passage to the second proximal end of the second passage and that houses the three-way valve. 3. The chemical sprayer of claim 1, further comprising a spacer member that couples the first elongated fluid passage to the second elongated fluid passage. 4. The chemical sprayer of claim 1, wherein the first nozzle has a fan shape so that spray from the first nozzle is constrained in a non-circular spray pattern. 5. The chemical sprayer of claim 1, wherein the second nozzle has a slotted shape so that spray from the second nozzle is constrained in a non-circular spray pattern. 6. The chemical sprayer of claim 1, further comprising: a. a turbulence causing member disposed in the transverse portion; and b. an air intake defined by the transverse portion and disposed downstream from the turbulence causing member. 7. The chemical sprayer of claim 6, wherein the turbulence causing member comprises a disk disposed transversely to the transverse portion, the disk defining a plurality of holes passing therethrough. 8. A chemical sprayer system, comprising: a. a three-way valve including an inlet port, that is capable of being coupled to a fluid source, a first outlet port, a second outlet port, and a three-state control that allows a user to place the three-way valve into one of a plurality of states, including: a first ON state in which the first outlet port is in fluid communication with the inlet port, a second ON state in which the second outlet port is in fluid communication with the inlet port, and an OFF state in which substantially no fluid is allowed to exit the inlet port to either the first outlet port or the second outlet port; b. a first elongated fluid passage having a first proximal end and an opposite first distal end, the first proximal end in fluid communication with the first outlet port, the first distal end terminating in a first nozzle, the first nozzle adapted for spraying foam, the first elongated fluid passage including: i. a first parallel portion, spaced apart from the second elongated fluid passage at a first distance; ii. a second parallel portion, spaced apart from the second elongated fluid passage at a second distance, the second distance being less than the first distance; iii. a transverse portion connecting the first parallel portion to the second parallel portion; iv. a disk disposed transversely to the transverse portion, the disk defining a plurality of holes passing therethrough; and v. an air intake defined by the transverse portion and disposed downstream from the disk; c. a second elongated fluid passage, spaced apart from and substantially parallel to the first elongated fluid passage, having a second proximal end and an opposite second distal end, the second proximal end in fluid communication with the second outlet port, the second distal end terminating in a second nozzle, the second nozzle adapted for spraying liquid phase fluids; and d. a connecting passage that couples the first proximal end of the first elongated passage to the second proximal end of the second passage and that houses the three-way valve. 9.
