ABSTRACT:
The present invention relates to a portable sprayer for applying a diluted product to a surface to be treated. The sprayer includes a housing including an inlet for supplying pressurized water to the sprayer, a first water only outlet, and a second diluted product only outlet. A mixing chamber is located within the housing. The mixing chamber is dimensioned to securely hold the product and is in fluid communication with the second outlet. A first flow passage extends through the housing. The first flow passage is in selective fluid communication with the inlet and the first outlet. A second flow passage extends through the housing. The second flow passage is in selective fluid communication with the first flow passage and the mixing chamber. A wall of the second flow passage is configured to direct the pressurized water flowing through the second flow passage into the mixing chamber to evenly dissolve the product and provide a generally consistent product to water ratio.
