Galvanized steel potable water supply and distribution pipes are commonly found with nominal pipe sizes from 3⁄8 inch (9.5 mm) to 2 inches (51 mm). It is rarely used today for new construction residential plumbing. Steel pipe has National Pipe Thread (NPT) standard tapered male threads, which connect with female tapered threads on elbows, tees, couplers, valves, and other fittings. Galvanized steel (often known simply as "galv" or "iron" in the plumbing trade) is relatively expensive, and difficult to work with due to weight and requirement of a pipe threader. It remains in common use for repair of existing "galv" systems and to satisfy building code non-combustibility requirements typically found in hotels, apartment buildings and other commercial applications. It is also extremely durable and resistant to mechanical abuse. Black lacquered steel pipe is the most widely used pipe material for fire sprinklers and natural gas.
Scott was very knowledgeable and happy to test out all items of my finikie hot water heater. He called in tech support and tested pressures and did a vent pipe test to check air flow. How do I know this, because he explained everything to me. One afternoon with him, and I could be a tech. All joking aside. I appreciate the continued support of Atomic. Scott's professionalism and willingness to keep me in the loop is spot on. Thanks Scott.
