The pipes, drains, and water systems hidden in a building get designed by you — laying out how water, waste, and gas move safely and to code. Engineering the systems behind every faucet and drain.
Mostly in CAD, you design and draft plumbing systems — water supply, drainage, gas, and the calculations and code behind them — working under engineers and coordinating with architects and other trades. Detail and code compliance are the craft, since a flaw becomes a leak or a code violation in the built world, costly to fix.
The harder part is coordinating with everyone else's systems — plumbing has to fit around structure, electrical, and HVAC. Codes are strict and vary by jurisdiction, revisions are constant, and the work is detail-heavy to the point of tedium. Scope ranges from homes to hospitals.
It tends to fit someone precise, methodical, and comfortable with codes and coordination. If you want fast or loosely defined work, the rigor can feel heavy. But if there's satisfaction in designing the unseen systems a building can't function without, the role tends to suit.
