Drain Cleaning for Garden City's 1.5-Inch Galvanized Waste Lines
Every Garden City cape and split-level from the 1950s was plumbed with 1.5-inch galvanized waste lines for the bathroom and kitchen drains. Seventy years of corrosion has narrowed the effective inside diameter to roughly two-thirds of original. Snaking pushes a hole through the gunk but does not restore flow. Hydro-jetting is the only intervention that actually scours the pipe wall back toward the original ID, and on Garden City's vintage galvanized it is the standard maintenance interval we recommend — about every 18-24 months until the lines come due for replacement.
