For the heavy root intrusion and grease common in San Anselmo’s older clay and Orangeburg laterals, hydro jetting scours the full pipe wall clean and keeps it clear far longer than a cable, which often just bores a hole through the blockage.
The mature oaks and redwoods that make San Anselmo beautiful send roots toward the moisture in aging sewer joints, then grow inside the pipe. We hydro jet the roots out and camera the line to find the entry point and recommend a lasting fix.
This could likely be because there is a larger clog in the sewer main line that is affecting all of the plumbing in your house.
Sewer cleaning is the cleaning of the larger sewer line, whereas drain cleaning refers to cleaning the drain of a singular plumbing fixture.
Hydro-jetting should be a safe and effective drain cleaning method for most plumbing. The only risk is older piping materials that can sustain damage easily.
Recurring clogs can be a sign of a larger sewer line issue like tree root intrusion, or a buildup of grease and other harder debris within the drain pipe.
If sewage is backing up anywhere in your house, immediately turn the water off and stop using the plumbing before calling an emergency plumber.
