In an unrenewed 1890s Richmond Hill Victorian, the supply lines are likely wrought iron or early galvanized steel — both installed before 1910 and now 110-plus years old. Cast-iron DWV from that era is standard. The heating system, if original, would be a gravity hot-water system or early steam rather than the forced hot-water systems that became standard in the 1920s. In practice, most of these homes have had at least partial plumbing work over 130 years, but it's common to find original cast-iron drain stacks still in service even in renovated buildings.
Yes, but it's a major project. Converting from one-pipe steam to forced hot water means replacing every steam radiator with hot-water baseboard or panel radiators, removing the steam mains and replacing them with smaller hot-water supply and return lines, installing a new boiler, and adding a circulation pump. In a Richmond Hill Victorian with 8–12 radiators, this is a multi-day job. Steam-to-hot-water conversions make the most sense when the existing radiators are damaged, the system is inefficient, or the building is being fully renovated anyway. If the steam system is otherwise sound, we'd often recommend maintaining it.
