Abstract
A sprayer system for spraying water, onto and for absorption by, a surrounding area, such as used in wastewater treatment. The sprayer system includes a substantially vertical tubular housing extending from a well base to a distal end from which water communicated to the sprayer system is discharged. The tubular housing includes an inner tubular casing slidably supporting a piston assembly which is movable from the well base to the distal end in response to water communicated from a source to the well base. The piston assembly includes a primary check valve that is biased into engagement with an associated seat and includes a spray nozzle located downstream of the main check valve. When water from the source is applied to an effective pressure area on the piston assembly, an upwardly directed force is applied to the piston assembly when water is delivered to the well base. At least one bypass passage communicates bypass water to a region defined between the piston housing and an inside wall of the tubular casing so that warming water is delivered from the well base and flows around the outside surface of the piston assembly, whereby icing, which would otherwise block movement of the piston assembly, is inhibited.
