I’ve been a master plumber since age 29. I know, it might seem odd to you that a builder is also a plumber. I was attracted to plumbing for several reasons. Designing a plumbing system is a fun and challenging three-dimensional puzzle. I still draw 3D riser diagrams for homeowners and builders. The drawings allow them to obtain plumbing permits, and it keeps my tiny gray cells active.
Water lines are not as complicated as drain, waste, and vent lines. That said, you can have volume and pressure problems if you don’t design water systems correctly. A year ago, I did an extensive long-distance consultation with a woman. Her plumber tried to supply a luxury shower with 1/2-inch diameter PEX hot and cold water lines. Water dribbled from the body sprays when the shower head was turned on. It was a horrible hot mess.
