Frequently asked questions
Snake a one-off clog in a healthy pipe. Jet a line that clogs on a schedule, or when grease or roots are the cause. Jetting cleans the full pipe wall, so it holds up 2 to 3 years instead of months.
Most Marin districts require it at point of sale. Ross Valley Sanitary District gives 90 days after close of escrow. See our Marin sewer lateral guide for your district.
A camera inspection. We run a CCTV camera through the line and show you the exact roots, cracks, or sags with distance markers, so you only fix what actually needs fixing.
