What causes backups in Redmond
The city says most sewer backups come from a plugged pipe, and tree roots can also infiltrate it. Redmond recommends not flushing any wipes, even ones labeled flushable, and it is unlawful to plant willow, poplar, cottonwood, soft maple or gum trees within thirty feet of a public or private sewer.
- Wipes and grease in the drain
- Tree roots in the lateral
- Plugged pipe at the main
- Failed or broken lateral
Whose pipe is it?
The homeowner is responsible for the sewer lateral from the home to the city main, while the city maintains the sewage collection system and King County handles regional wastewater treatment. A plumber clears or repairs the lateral, and the restoration crew handles the cleanup.
Containment, removal, treatment
Plastic sheeting and negative air isolate the affected rooms. Carpet, pad, wet drywall and anything porous that touched the water is bagged and removed, because it cannot be cleaned safely.
An EPA-registered antimicrobial goes onto every cleaned surface, and HEPA air scrubbers run while the area dries. See water extraction for the pumping stage and structural drying for the readings.
