Abstract: Examples provide a configurable, modular manifold system for distributing water. The manifold receives water via a first supply line dropped vertically down from a ceiling structure. The first supply line is connected to a water source, such as a water tank or pre-existing water line without demolition. The water may be heated or filtered and then supplied to a fixture or other device via a perpendicular second supply line. Drainage from the fixture is received via a drainage line. The drainage accumulates in an accumulator tank. The drainage water is pumped out via a second vertical drainage line carrying the drainage water away. The second line eventually connects to a pre-existing sewage line or septic system for treatment. The manifold may be moved or relocated easily to provide water to fixtures or other devices modularly without alteration of fixtures or access demolition to existing structures.
