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 (22) to which the other filtra- tion purification system elements may be matedly engaged. Other system elements may include various filters (62) of fil- ter modules (24), as well as, system. leads for conveying in- coming tap water in (72), outgoing waste water out to drain (74) and purified water from the filter section (76) to a sto- rage tank (3) until desired for use. The fluid flow control de- vice (22) is preferably a unitary thermoplastic body having a number of discrete fluid flow passages (182, 188, 194, 200) extending therein. In a preferred embodiment, the fluid flow control device (22) includes integrally formed input/output connector features (38), filter-receiving socket portions (90) and an automatic shut off valve (50) disposed in fluid flow communication with certain ones of the passages.
