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.
