Project Overview & Homeowner Objectives in Zelienople, Harmony & Evans City

Many classic residences across Zelienople, Harmony, and Evans City, PA—particularly historic homes along Main Street, High Street, and the Harmony Historic District—still rely on original 60-to-90-year-old galvanized steel supply pipes and hubbed cast-iron drain stacks. In this turnkey plumbing overhaul, the homeowners were dealing with rusty brown water every morning, severe pressure drops whenever a toilet was flushed while someone was showering, a weeping 50-gallon atmospheric tank water heater, and a cracked 4-inch cast-iron main stack leaking sewer gas into an upstairs closet.

Property Profile & Pre-Renovation Challenges

Inside the cut-open galvanized pipes, rust and mineral scale had constricted the 3/4-inch interior diameter down to the width of a drinking straw. Worse, most standalone plumbers rip giant holes in historic plaster walls to run new pipes and leave the homeowner scrambling to hire a separate drywall and paint contractor to put their house back together.

Scope of Work & Single-Team Turnkey Execution

• Certified EPA Lead-Safe containment for precision surgical wall and ceiling access cuts in the pre-1978 home.
• Complete whole-house plumbing repipe using an Uponor PEX-A home-run manifold system and Schedule 40 PVC drain stack replacement.
• Installation of a Navien condensing tankless water heater, pressure-reducing valve, and whole-house filtration system.
• In-house electrical dedicated circuit wiring, HVAC combustion air balancing, and plaster/drywall restoration.

Uponor PEX-A Manifold Engineering & Cast-Iron Stack Replacement

Home-Run Manifold Pressure Balancing & Freeze Resilience

Our licensed plumbers abandoned the corroded galvanized piping and installed a central copper-and-polymer distribution manifold in the basement, running continuous, joint-free lines of Uponor AquaPEX (PEX-A) tubing directly through interior wall cavities to every kitchen, laundry, and bathroom fixture. Because PEX-A uses ASTM F1960 expansion fittings rather than restrictive crimp rings, there is zero interior diameter reduction—delivering rock-steady water pressure even when two showers and the washing machine run simultaneously. Furthermore, PEX-A’s thermal memory allows it to expand if exposed to extreme Western PA winter drafts and contract back to its original shape, drastically reducing burst-pipe risks.

Replacing the Cracked Cast-Iron Main Stack

Working from the basement cleanout up through the roof flashing, our crew safely supported and removed the cracked 4-inch vertical cast-iron soil stack, replacing it with Schedule 40 PVC wrapped in acoustic mineral wool insulation inside the first-floor dining room chase so flushing toilets upstairs remain whisper-quiet.

Navien Condensing Tankless Water Heater & Turnkey Wall Restoration

Endless Hot Water & Complete Plaster/Drywall Repair

We removed the rusted 50-gallon tank and mounted a wall-hung Navien NPE-240A2 199,900 BTU condensing tankless water heater vented directly outdoors with dual 2-inch Schedule 40 PVC intake and exhaust pipes, paired with a Watts bronze pressure-reducing valve (PRV) and whole-house carbon filtration. Our in-house electricians wired a dedicated 120V GFCI circuit for the tankless unit, and the moment our PA UCC plumbing inspection passed, our in-house carpenters and drywall finishers closed, skim-coated, and painted every surgical access opening—leaving the historic home spotless.
