House Water Supply Plumbing Diagram

This residential plumbing schematic traces cold water from the building main through the primary shutoff. One branch feeds the water heater and the remaining cold-water branches feed the kitchen sink, bathroom sink, and shower. The heater outlet then supplies hot water to the same fixtures. Labels distinguish the 3/4-inch main from the 1/2-inch fixture branches. The drawing focuses on how the supply system connects rather than the physical path through walls and floors. It is useful for explaining a small remodel or organizing a discussion with a plumber. It does not replace a code-compliant permit drawing. Add fixture stops, backflow protection, drainage, venting, pipe materials, and actual routing as the project requires.
