Abstract
New and improved filtration purification or water treatment systems for providing improved purified drinking water at a point of use are provided in a substantially leak-free fluid flow control device to which the other filtration purification system elements may be matedly engaged. Other system elements may include various filters or filter modules, as well as.[.,.]. system leads for conveying incoming tap water in, outgoing waste water out to drain and purified water from the filter section to a storage tank until desired for use. The fluid flow control device is preferably a unitary thermoplastic body having a number of discrete fluid flow passages extending therein. In a preferred embodiment, the fluid flow control device includes integrally formed input/output connector features, filter-receiving socket portions and an automatic shut off valve disposed in fluid flow communication with certain ones of the passages.
