Sewer Cleaning questions, answered by experts

If you’re wondering whether rats can come up the toilet, the unfortunate answer is yes, it’s possible, though it’s extremely rare. These rodents are excellent swimmers and can travel through sewer pipes in search of food, and they may follow plumbing lines leading to your home if they’re drawn by the scent of scraps and waste. The toilet’s U-bend holds a small pocket of air, which can help a rat catch its breath before making its final push into your bathroom. While more common in cities with larger rat populations, this can happen anywhere with connected sewer systems; sealing entry points and keeping drains clean can help reduce the risk.

Ideally, you might find that you only need to clean the sewer line or remove a clog from the main line. That costs $200 to $300. However, “sewer main clogs can cost upwards of $1,000 to clear, depending on what is causing the clog, distance from accessible cleanouts to the clog, and whether there is occupied space below the clogged line (apartment buildings, condos, etc.),” says Botelho.

If the toilet is overflowing but there’s no clog, that’s a sign that the issue is deeper in the system, and plunging may not help. A blockage in your home’s plumbing, the plumbing vent, or even city sewer lines can cause toilets to overflow. The issue could also be the toilet itself if the filler float isn’t set to the correct height or if parts are damaged or worn out.

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.

DIY is not recommended due to safety risks and specialized equipment requirements. Hire professionals for effective clearing.
