The Real Problem
Cincinnati Has 150 Years of Housing — And Every Era Has Different Plumbing Needs
Cincinnati is one of the oldest cities in the Midwest, and its neighborhoods reflect that. The Greater Cincinnati area spans everything from pre-Civil War brick rowhouses in Over-the-Rhine to post-war ranches in the eastern suburbs to 1990s colonials in the outer ring. Every era of construction brought different plumbing materials — lead and galvanized steel, cast iron, copper, early PVC — and each is aging in its own way right now.
On the east side and in the suburban counties, the most common issues are cast iron drain systems that have hit their lifespan, aging sewer laterals with root intrusion from mature trees, and water heaters on the back side of their useful life. These aren’t dramatic failures — they’re slow declines that compound over time until something finally backs up or gives out.
FlowMax serves the east side of Cincinnati and the surrounding counties — Clermont, Hamilton, and Brown — with the same honest, local approach regardless of the neighborhood or the era of the home.

Cincinnati Has Plenty of Plumbers — Not Many Like This
Greater Cincinnati has no shortage of plumbing options — big franchises, national brands, call centers that dispatch whoever’s available. FlowMax is something different. Ronnie Niehaus built this business on a straightforward idea: show up when you say you will, diagnose honestly, price clearly, and do the work right. After 24 years in the trade and a son working alongside him full-time, that’s still the whole model.
- 24 years in the trade — Ronnie has worked on Cincinnati-area homes across every era of construction and every plumbing material.
- Family-owned — not a franchise — No call center, no rotating crews. You talk to the people doing the work.
- Upfront pricing, every time — The price we quote is the price on the invoice. No surprise line items.
- Tri-county coverage — Hamilton, Clermont, and Brown County. One team, one standard of work across all three.
- Built for the long haul — Blake Niehaus works full-time alongside Ronnie. This business has a succession plan.
