Sewer Cleaning questions, answered by experts

Regular maintenance, such as not disposing of grease or coffee grounds down the sink and routine use of strainers, can prevent clogs.

It can take anywhere from one month to a couple of years for tree roots to grow back in sewer lines. Tree roots can cause extreme havoc on your sewer lines, potentially cracking them and causing untreated wastewater to make its way into the groundwater. Have a landscaping pro remove trees and roots before installing your system, or call a pro to do it retroactively as soon as you can.

No, you typically cannot use metal detectors to find your sewer line. Most sewer lines are made of non-metallic materials such as PVC, clay, or cast iron, which are not detectable by standard metal detectors. Metal detectors are designed to locate metallic objects, so they won't be effective for identifying the path of a non-metallic sewer line. To locate your sewer line accurately, it's best to use other methods.

Snaking a drain can take as little as a few minutes for small, simple clogs, up to two hours or more for tough clogs located further down the drain line. For tougher clogs, a professional drain cleaner can likely get the job done much more quickly because they have the necessary tools and expertise. However, your drain cleaning pro might not be able to give you a firm time estimate until inspecting the clog and its surrounding plumbing.

Clearing typically takes 1-2 hours, depending on the blockage size and location.
