Elmhurst developed in two distinct phases: a prewar layer of 1920s brick apartment buildings along Broadway and Colonial and Tudor rowhouses on the side streets, followed by postwar multi-family construction and high-rises along Queens Boulevard after the Long Island Expressway arrived in the 1950s. The 1920s walk-ups carry original galvanized supply and cast-iron DWV; steam heat is common in that generation of buildings. The postwar layer introduced copper supply and forced-air or hot-water systems, meaning any given block in Elmhurst can present both plumbing generations within a few doors of each other — an important variable to diagnose before scoping a repiping or boiler job.

Our Elmhurst apartment building has a mix of galvanized and copper supply from different renovation eras — is that a problem?

Mixed galvanized and copper supply is common in Elmhurst buildings where one or two floors were repiped at some point but the rest wasn't. The main issue is the galvanized-to-copper transition joint, which can corrode from galvanic action between the two metals over time. It's also worth knowing whether the copper sections are from the 1950s–1960s or more recent — both can develop issues, but the failure modes differ. A systematic inspection tells you which sections are the priority.

How do we know which generation of plumbing our Elmhurst building has without opening walls?

Water pressure and color are the two simplest non-invasive indicators. Low pressure throughout — especially on upper floors — suggests galvanized pipes narrowing internally. Rust-colored hot water at first draw is another galvanized sign. For a definitive answer, we can inspect the supply connections in the basement mechanical room, which are usually accessible without opening walls, and tell you from there whether what goes upstairs is galvanized or copper.
