Valley Mills is Greenwood's settled west — a residential area of established streets and homes that span the city's great building decades, from post-war ranches to the subdivisions that followed. Its plumbing is the middle chapter of the Greenwood story: clay largely gone from the youngest streets, cast iron doing the heavy work in the older ones, and everywhere the full basements that make this city's drainage a below-grade discipline. Nothing in Valley Mills is antique, and nothing is new — which makes it the purest maintenance neighbourhood in Greenwood.
Cast iron's ageing is the area's central fact. Iron does not fail suddenly; it roughens from the inside over decades, growing a tuberculated crust that slows flow, catches grease and eventually thins at the channel. A Valley Mills line at fifty years is not a problem — it is a schedule: descaling jetting can restore much of its bore, a camera can grade what remains, and the owner can plan the relining or replacement decade with information instead of dread. The neighbourhood rewards exactly the temperament its homes were built for: steady, unglamorous upkeep.
