Sewer Cleaning FAQs, answered by experts

Depending on the home, wastewater either goes into a septic tank and seeps back into the backyard or is sent via sewer system to a local sewage-treatment plant. Septic systems naturally separate different components of the waste so that it can naturally and safely disperse it. They are usually reserved for homes not served by a municipal sewage department (like rural homes). A treatment plant, on the other hand, speeds up that process through screening and purification.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

Snakes can occasionally enter homes through shower drains, although it’s quite rare. This can happen when they follow sewer pipes or accidentally find their way into plumbing systems. To minimize the risk, consider installing drain covers or stoppers on your shower drains. Always keep drains closed when they’re not in use, especially in areas where snakes are known to be active.

If you’ll be digging up your floor to get access to your pipes when putting in a sewer backflow preventer, this would also be a good time to take care of any other plumbing issues or renovations. For example, you could install additional pipes for a basement bathroom. Since the floor will be sealed over with concrete when you’re done, now’s a good time to take care of those bigger tasks.

Simple blockages can be cleared using household plungers or manual snakes, provided no severe plumbing issues exist.
