Sewer Cleaning FAQs, answered by experts

With a one-way cleanout, you can access your sewer line from one direction. Depending on the way it curves, a plumber can either access the side of the pipe that goes into your home or the side that goes to your yard. On the other hand, two-way cleanouts allow pros to access both sides of the sewer line, thanks to their dual-pipe design (they’re usually U-shaped).

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.

There are a few things that can happen to your sewer system if you don’t fix it. These include rainwater entering it and causing rust and corrosion, dirt and debris leading to blockages, small animals getting stuck inside and clogging your sewer line or entering your home, and shortening the sewer system’s life span. 

Without a cap, nothing prevents toxic and non-toxic gasses like methane and hydrogen sulfide from slowly escaping your sewer system and entering your home and the surrounding atmosphere, resulting in a foul sewer odor throughout your house.

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.

You should not attempt to snake your sewer yourself. Accessing and snaking your sewer requires heavy-duty equipment, and while renting is possible, misusing it can damage your sewer main and leave you with very expensive repair costs, not to mention potential environmental issues and severe water damage. Accessing your sewer also exposes you to hazardous sewer gasses, and failing to seal the sewer properly after work can be very dangerous. It’s always best to hire a professional sewer cleaner near you to handle this type of work.
