Residential Crawlspace Drain Repipe
This project record follows a broad drain-pipe replacement routed beneath a residential floor. The photographs show the replacement main run, multiple branch connections, direction changes, and supports inside a constrained crawlspace. The page focuses on the visible installation sequence and avoids adding a city, date, cause, permit, inspection, or final test result that is not established by the source record.
Project at a glance
A coordinated route beneath existing floor framing
The selected images show how multiple drain branches were gathered into a replacement route while working around joists, beams, foundation walls, existing supply piping, and limited access. Two source photographs containing a person near the access opening were excluded from public use.
Working conditions
Low-clearance access beneath existing framing required the pipe route and supports to be coordinated in place.
Documented components
The photographs show black drain piping, branch fittings, direction changes, and metal support hangers.
Alignment documentation
Two close views show a level used during installation; they are described as in-progress checks, not a final test result.
Documented work sequence
What the available project record supports
Review the crawlspace route
The available path beneath the structure was assessed around framing, foundation walls, and other visible building systems.
Lay out the replacement main
A continuous replacement drain route was positioned through the accessible crawlspace.
Bring branches into the route
Individual drain branches were connected through fittings suited to the visible changes in direction.
Support the installed piping
Hangers visible in the photographs hold the route beneath the floor framing.
Check alignment while work is open
A level was photographed against the pipe during installation. The source does not establish the final test or closeout result, so none is claimed.
Original USC field photographs
Selected views from this project record
Each public image was reviewed for privacy, stripped of metadata, and assigned a natural description limited to what the frame shows.
Verified project scope
Clear facts without invented closeout details
The portfolio does not identify a city, project date, failure cause, permit, inspection, final flow test, leak test, completed closeout, customer name, address, or price.
The page can be expanded later only when a verified project record supports the additional fact.
