Alexapure Pro is a groundbreaking, gravity-fed water filtration system that outperforms others, for less. It sounds like such a simple theory too . I think it would help if you can provide a schematic and a couple of photos of your system, please. Generally, the gravitational networks are designed as branched systems and in order to maintain their looped configuration the missing links are joined by pipes of nominal diameters. Gravity systems are simple but very complex at the same time. Students follow the engineering design process to design a gravity-fed water system. $55.00.
