Cast Iron Drain Repipe to PVC
Replace deteriorated cast iron drain piping with Schedule 40 PVC DWV for a cleaner, corrosion-resistant drainage system in Miami and South Florida properties.
Replace Deteriorated Cast Iron with Modern PVC Drain Piping
Older cast iron drain systems can deteriorate internally and externally over time. Scale, corrosion, cracks and rough pipe surfaces can contribute to repeated drainage problems.
Jay & Norman Plumbing Services can evaluate the existing drainage system, identify affected cast iron sections and replace appropriate piping with Schedule 40 PVC DWV.

Signs Your Cast Iron Drains May Need Replacement
A camera inspection and drainage evaluation can help determine whether repeated problems are related to localized damage or broader deterioration of the cast iron system.
Repeated Drain Backups
Frequent backups can indicate damaged, scaled or restricted drain piping that requires further evaluation.
Slow Drainage
Heavy internal scale or deteriorated pipe surfaces can reduce usable pipe diameter and affect drainage.
Sewer Odors
Persistent sewer odors may require inspection for damaged drain piping, fittings or traps.
Cracks or Leaks
Aging cast iron can develop cracks, holes or weak sections that allow wastewater to escape.
Corrosion & Scaling
Internal rust and scale can create rough drainage surfaces and contribute to recurring clogs.
Older Drain System
Older homes with original cast iron drainage may benefit from inspection when recurring plumbing issues develop.
From Cast Iron Inspection to New PVC Drainage
The exact repipe method depends on the location of the existing drain lines, property layout, access conditions and findings from the inspection.
Camera Inspection & Diagnosis
Existing drain lines are evaluated using available access points and sewer-camera diagnostics to identify deterioration, scale, cracks, restrictions or damaged sections.
Mark Drain Route & Access Areas
Drain-line routing and required access points are identified. Depending on the property, access may involve slab, wall or other plumbing-access areas.
Open Required Access
Concrete slab, wall or other surfaces are opened where necessary to reach the affected cast iron piping and complete the approved scope.
Remove Deteriorated Cast Iron
Affected cast iron pipe sections are removed and the surrounding drainage system is prepared for installation of the new PVC DWV piping.
Install Schedule 40 PVC
New Schedule 40 PVC DWV piping is installed using suitable fittings, couplings, hangers and required drainage pitch. Cleanouts are installed where appropriate.
Reconnect Fixtures & Branch Lines
Existing approved fixtures and branch lines are reconnected to the new PVC system using appropriate transition fittings and connections.
Test & Inspect
New piping is checked for alignment, drainage and accessible connection integrity. Flow testing and camera verification can be completed before closing access areas.
Close Access & Cleanup
Concrete slab openings included in the scope can be restored with concrete after inspection. Optional drywall patching can be quoted separately where required.
A Modern Alternative to Aging Cast Iron Drains
Schedule 40 PVC DWV is widely used for modern drainage installations and does not rust or develop the same internal corrosion and scale associated with aging cast iron.
Important Parts of a Proper Drain Repipe
Replacing cast iron involves more than installing new pipe. Drain slope, fittings, supports, transitions and access all affect long-term system performance.
Proper Pitch
PVC drain piping is installed with suitable slope based on line size, routing and installation conditions.
Hangers & Supports
Appropriate supports help maintain alignment and drainage pitch along accessible piping runs.
Cleanouts
Cleanouts may be installed at suitable locations to support future inspection and drain maintenance.
Transition Couplings
Approved transition fittings and couplings are used where new PVC connects to retained piping.
