Overview

Cellino Plumbing, Heating, Cooling & Electric was called to a single-family home in Cheektowaga, NY, to address a failing underground sewer and water line system. The existing piping, trap, and fittings had deteriorated to the point where repair was no longer viable. A full excavation and replacement were needed to restore the system to reliable, long-term operation.

 

  • Cut and broke up the concrete floor to excavate down to the trap and the affected section of underground piping
  • Removed and replaced approximately 4 feet of deteriorated pipe and fittings, and installed a new trap, backwater valve, and gate valve
  • Repiped the water meter and riser and reconnected the venting to align with the updated system configuration
  • Backfilled the excavated area with stone and poured new concrete to fully restore the floor surface

 

All work was completed by Cellino’s licensed plumbers in accordance with applicable codes and industry standards.

Key Challenges

Underground sewer and water line work in an existing home presents a set of challenges that go well beyond what’s visible on the surface:

 

  • Concrete Demolition & Controlled Excavation: Reaching the buried sewer and water lines required cutting and breaking up the concrete floor without damaging adjacent piping, the surrounding structure, or nearby finished areas. Precision here determines whether the repair stays contained or creates new problems.
  • Deteriorated Pipe Removal in a Confined System: Removing 4 feet of failing pipe and fittings from an active underground system required careful disconnection and staging to avoid disturbing the surrounding piping network. Any misalignment during removal can compromise the integrity of the remaining connections.
  • Trap, Backwater Valve & Gate Valve Coordination: Installing a new trap alongside a backwater valve and gate valve in the same section of reworked piping required precise sequencing and positioning. Each component has specific installation requirements, and they all had to work together correctly within the updated system layout.
  • Water Meter & Riser Repipe Alignment: Repiping the water meter and riser to align with the updated piping configuration added complexity. The connections had to be made accurately to ensure proper flow, pressure, and code compliance at the meter interface.

 

Surface Restoration to Original Condition: Once the underground work was complete, the excavated area had to be backfilled with stone for proper drainage and support before new concrete was poured. A poor restoration compromises the long-term stability of the repair and leaves the homeowner with a substandard finished surface.

Our Approach

Cellino approached this project in a logical sequence: excavation first, system rebuild second, and surface restoration last. This way each phase was correctly completed before going to the next:

 

  • Targeted Concrete Cutting & Excavation: Our team cut and broke up the concrete in the precise area needed to access the sewer and water lines, exposing the trap and the affected section of piping without overextending the work area.
  •  Piping & Fitting Replacement: Approximately 4 feet of deteriorated piping and fittings were removed and replaced with new materials, restoring the integrity of the underground system at its weakest point.
  • New Trap, Backwater Valve & Gate Valve Installation: A new trap was installed to maintain a proper seal between the drainage system and the living space. The backwater valve prevents sewer backflow, and the gate valve gives the homeowner system shutoff control.
  • Water Meter & Riser Repipe: The water meter and riser were repiped to align with the updated piping configuration, ensuring proper flow and pressure and a clean connection at the meter interface.
  • Venting Reconnection: The venting was reconnected to the updated system to maintain proper air circulation and prevent siphoning or pressure issues within the drainage lines.

 

Stone Backfill & Concrete Restoration: The excavated area was backfilled with stone to provide proper drainage and structural support beneath the surface. New concrete was then poured to restore the floor to its original condition, leaving no visible evidence of the repair.

result

What was a deteriorating underground system prone to failure is now a fully rebuilt, code-compliant sewer and water line installation with improved safeguards and a restored surface above it. The Cheektowaga homeowner now has a properly functioning system and the assurance that a qualified technician installed it correctly.

 

The new trap maintains the proper seal between the drainage system and the home’s living space. The backwater valve provides active protection against sewer backflow, a critical upgrade for any home on an aging municipal system, and the gate valve gives the homeowner direct shutoff control they didn’t have before. The water meter and riser are properly aligned and functioning at the correct flow and pressure.

 

The concrete surface above the repair has been fully restored with new poured concrete over a stone backfill base. This leaves the floor structurally sound and visually consistent with the surrounding area. All work was completed in accordance with applicable codes, with no deferred items or required follow-up visits.

From concrete demolition to the final pour, every decision Cellino made was driven by what the system needed to perform reliably for years, not just what was fastest to close out.

Frequently Asked Questions

Common signs include recurring drain backups, slow drains throughout the home, gurgling sounds from drains, water discoloration, unexplained wet spots on floors, or a noticeable sewage odor. A licensed plumber can inspect the system and determine whether repair or replacement is needed.

A backwater valve is a one-way valve installed in the sewer line that prevents sewage from flowing back into the home during a municipal system overload or backup. It is one of the most effective protections a homeowner can add to an older plumbing system.

A gate valve provides a manual shutoff point within the plumbing system, allowing a specific section of piping to be isolated without shutting off water to the entire home. It gives homeowners and plumbers more control during repairs or emergencies.

The materials used depend on the existing system configuration and local code requirements. Cellino selects materials appropriate for each specific application to ensure durability, code compliance, and long-term performance.

Yes. Cellino backfills the excavated area with stone for proper drainage and structural support, then pours new concrete to restore the surface to its original condition. The goal is to leave the home looking as close to pre-work condition as possible.
