The new Little Giant Inline 400 Pressure Boosting System (shown in cutaway) is a compact and economical solution to most water pressure improvement needs. The Inline 400 couples a pump and motor with simple flow-based controls to provide a typical water pressure boost of up to 40 psi, depending on the application’s need. The unit’s symmetrical design allows for easy installation, mounting either vertically or horizontally to fit within most existing plumbing configurations — including those where space is limited. This powerful yet quiet system is ideal for city water pressure boosting, pressurizing water from a cistern tank, re-pressurizing after filtration and irrigation system boosting applications.
