FAQ – DRAIN CLEANING & SEWER SERVICES
How do I know if my drain is clogged?
You might notice slow-draining sinks, gurgling sounds, foul odors, or water backups. Our team can quickly identify and fix the issue.
How often should I clean my drains?
We recommend drain maintenance every 6–12 months to prevent buildup and costly repairs. Hydro jetting and inspections are excellent preventive options.
What are signs of a sewer line issue?
Multiple drain clogs, sewer smells, soggy patches in the yard, or toilet backups may indicate a damaged sewer line.
Do you offer emergency drain services?
Yes! Knockout Plumbing is available for 24/7 emergency drain and sewer repairs in the Seattle area.
What’s the difference between sewer lining and replacement?
Sewer lining is a trenchless option that creates a new inner pipe without digging. Replacement involves removing and replacing the damaged pipe, typically for more severe cases.
