The problem on this Austin site
Six kitchen tenants shared one 6-inch cast iron main under the slab. Backups were hitting the two tenants furthest downstream about every ten days, and the property manager was absorbing after-hours emergency calls with no evidence of who or what was causing it.
How our NASSCO-certified crew approached it
- Scoped the 6-inch main first to separate a maintenance problem from a structural one before any jetting was quoted
- Ran warthog and chain-free nozzles overnight from downstream to upstream so grease was carried out, not packed forward
- Cleared the interceptor discharge line in the same window so the main would not reload
- Re-scoped the full run on camera before opening and issued footage-marked video tied to each tenant tie-in
What the camera documented
- Hardened grease reducing the main to roughly 25 percent of its design diameter across a 40 ft run
- Grease loading concentrated downstream of two specific tenant tie-ins, documented on video with footage marks
- No structural defects in the cast iron - the failure was maintenance, not pipe condition
- Interceptor discharge line partially blocked, feeding the problem back into the main
Measurable results
- Hydro-jetted back to full diameter overnight, with a verification scope run before the first tenant opened
- Footage-marked video gave the property manager tenant-specific evidence for the grease policy conversation
- Quarterly jetting and scope schedule put in place; no emergency backups reported since
