Follow the replacement of worn drain and waste piping in an existing home. Ten illustrated stages show protected access, new drainage routes, material transitions, vent connections, cleanouts, and fixture reconnection.

The existing drain and waste routes are reviewed for condition, access, and the fixtures they serve. The replacement scope is coordinated with the retained drainage and vent connections.
Finished floors and adjacent rooms are protected while selected access areas are opened. The exposed piping can then be reviewed and the work sequence coordinated around the existing structure.
Worn sections are removed in controlled stages while retained heavy piping is supported. Removed pieces are collected away from finished surfaces, and temporary closures protect affected openings.
Replacement drainage follows the planned gravity route with compatible fittings and supports. The illustrated branch uses a directional wye, with the piping routed beneath intact floor framing.
Where retained cast iron connects to replacement ABS, a suitable transition assembly is selected for the two pipe materials and their outside diameters. Both sides remain supported while the connection is secured.
The fixture drainage connection is coordinated with its vent path. This upright sanitary tee illustrates a future trap-arm connection to a vertical drain below and a vent continuing upward.
Cleanouts are placed where the affected drainage can be serviced. The opening remains reachable after the surrounding cabinetry and finishes are complete.
Replacement joints and test closures are reviewed while the work remains exposed. Required water testing and rough inspection are coordinated before the affected piping is concealed.
The fixture waste outlet reconnects through a serviceable trap to the prepared wall drainage connection. The final assembly is aligned without strain and checked at its accessible joints.
The reconnected fixtures are operated to review drainage and visible leakage. Remaining adjustments, finish coordination, and required final inspection complete the affected work.
