Abstract |
To examine the water use, energy use, use time, and user satisfaction of high-efficiency Pre-Rinse Spray Valves (PRSVs), Environmental Protection Agency (EPA) initiated a 12-week field study at 10 commercial kitchen facilities in the Washington, DC, and Boston, Massachusetts, areas. The intent of this research was to answer the questions outlined in EPA's Pre-Rinse Spray Valves Research Study Scope, dated October 26, 2009. The objectives of the study were to determine if: High-efficiency PRSVs save water; Users require more time to rinse dishes when using high-efficiency PRSVs; The ASTM F2324 cleanability test method accurately predicts whether a user will spend more time using a given PRSV in the field; Users are less satisfied with high-efficiency PRSVs; Users are less satisfied with PRSVs that they have to use for more time in order to rinse the dishes; and Users are more satisfied with PRSVs that have lower ASTM F2324 cleanability times. |
