Sewer Cleaning questions, answered by experts

Main sewer lines can clog for several reasons. For example, if you regularly dump oil or grease down your drain, it could eventually block your line. Sometimes, tree roots can penetrate and grow inside old sewer pipes, creating a major blockage. Flushing bulky items (like paper towels, diapers, or baby wipes) can also clog your plumbing system.

Cat pee has a strong ammonia-like smell, so if you smell cat pee but don’t have a cat or don’t suspect your cat has any accidents, there could be other issues at hand. Aside from pet urine, your house may smell like cat pee from leaking freon from an old fridge, mold, spilled cleaning supplies, or even outside odors from nearby farms.

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

Food grease, soap buildup, paper products, and tree roots often cause serious clogs.

It’ll take 20 to 30 minutes to unclog a sewer line using a drain snake or drain cleaner. If you hire a professional, you should expect them to be on-site for three hours or less. In addition to clearing the clog, they’ll do other routine inspections, which adds to the overall time (and cost) required.
