Dublin, Ohio
Dublin's houses are three different ages. So are their plumbing problems.
A stone house off Bridge Street, a 1979 Muirfield colonial and a 2012 build on the west side have almost nothing in common below the floor.
Dublin is fifteen minutes down Sawmill from the shop, and it is the city where guessing gets a plumber into the most trouble. The address tells you almost nothing until you know when the house was built.
There are effectively three Dublins. Historic Dublin, the nineteenth-century stone and frame houses around Bridge and High, runs on the oldest materials in the city: cast iron, galvanized branches, and drainage laid out before anyone was thinking about a second-floor laundry. Muirfield Village built out from 1972 through the 1980s around the Nicklaus course, and a surprising number of those homes are still original inside, which puts them squarely in the polybutylene, early-CPVC and forty-year-old cast-iron window. Then the west side and the Jerome Township edge filled in from the 1990s through the 2010s in copper and early PEX, and that generation is now mid-life rather than new.
One thing all three share is the water. Dublin's public distribution system is supplied by the City of Columbus, which runs roughly seven to nine grains per gallon and shifts with the season depending on whether Hoover, O'Shaughnessy or Griggs is carrying the load. Residents notice the taste change; water heaters and tankless units notice the minerals. The other near-universal Dublin feature is irrigation. Almost every Muirfield and west-side subdivision has a system, which means outdoor supply lines, hose bibs and backflow devices are a recurring winter and spring conversation here in a way they simply are not in older, un-irrigated neighborhoods.
Local conditions
What we run into in Dublin
Polybutylene and early CPVC in the Muirfield-era build
Grey polybutylene supply pipe went into a great many homes built between roughly 1978 and 1995, and Muirfield's build-out sits inside that window. It rarely fails in the middle of a run. It fails at the fittings, where the crimped acetal or metal insert meets pipe that has slowly lost its flexibility, and it usually fails behind drywall with no warning. Early CPVC from the same period gets brittle at the same joints. If your house has grey plastic supply lines with crimp rings, that is worth knowing before it announces itself.
Cast-iron drain stacks past forty
The original Muirfield-era drainage is cast iron, and cast iron does not fail like copper. It scales inward until the effective diameter is half of what it started as, then channels along the bottom of the pipe until the wall thins through. The symptoms read as a slow drain problem for years before they become a pipe problem. A camera run tells you which one you actually have, and it is the difference between a cleaning and a section replacement.
Seasonal hardness from the Columbus supply
Seven to nine grains per gallon, varying through the year with the reservoir feeding the system, is enough to lay sediment in a tank and to narrow a tankless heat exchanger if it is never descaled. In Dublin this shows up most in the tankless units that went into the newer west-side homes, where owners were told the unit lasts twenty years and were not told that the twenty years assumes annual descaling on water like this.
Irrigation, hose bibs and outdoor supply
Irrigation is close to universal here, and everything that serves it lives outside where it freezes. Split hose bibs, cracked outdoor supply lines and a valve nobody has closed since the system was installed are ordinary Dublin spring calls. Worth noting separately: Ohio EPA rules and the Ohio Basic Plumbing Code require testable irrigation backflow devices to be tested annually by a certified tester, so that is a date to keep on the calendar whether or not anything is leaking.
Historic Dublin's original materials
The oldest houses near Bridge and High were plumbed in eras with different assumptions: galvanized supply that has corroded closed from the inside, drum traps, and fixtures fed without isolation valves. Add a historic district that constrains what can change on the exterior and the work becomes a planning exercise as much as a plumbing one. We would rather talk that through before we open a wall than after.
