"The technician arrived about 30 minutes late without calling to tell me; looked at the toilets and identified the problem fairly quickly. He was knowledgeable and considerate. The cost was a bit on the high side, but I never saw a plumbing problem that isn't resoved without a hefty fee! I recommend them again, though."

Sewer Cleaning FAQs, answered by experts

The best drain cleaners are biodegradable ones or a mixture of baking soda and vinegar. Strong, caustic chemicals may seem appealing with promises of unclogging your drain quickly, but liquid drain cleaners can cause damage to your pipes over time. Consider making your own drain cleaner with baking soda and vinegar.

That pungent rotten egg smell coming from your drain is likely the buildup of biofilm—hair, skin, and soap scum that turns into a black sticky mess. In this case, pouring down near-boiling water, baking soda, and white vinegar will remove the smell. Keep in mind that a rotten egg smell is occasionally a sign of larger sewage line clogs and other related issues.

An active cleaning agent and a drain snake is the best way to clean a main sewer line. You can purchase a regular or enzyme drain cleaner or make a DIY drain cleaner with baking soda. Use your chosen solution at least once a month or as needed to keep your sewer line clear. 

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

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.
