Sewer Cleaning FAQs, answered by experts

Toilet paper is the only material that you should flush down toilets. Other items like wipes, paper towels, feminine hygiene products, dental floss, and medications should be disposed of in the trash. Flushing these items can lead to plumbing issues and damage to sewage systems. Grease and cooking oils should also be avoided as they can solidify in pipes, causing blockages. Proper disposal helps prevent clogs and ensures the efficient operation of wastewater treatment systems while protecting the environment.

To get rid of a sewer smell in your crawl space, you’ll have to find the source of the problem. If it has to do with your sewer lines, then repairing the line will help. You may need to make other repairs, like fixing your sump pump or encapsulating your crawl space to reduce moisture. After you make the repair, depending on the issue, you may still need to clean out your crawl space to get rid of the stink.

There is conflicting advice on whether to leave a baking soda and vinegar mixture in a drain overnight. Some sources suggest it can be effective for tough clogs, recommending that you flush the drain with warm water in the morning as part of a monthly cleaning routine. However, other experts advise against leaving the mixture in for extended periods, as its caustic nature could corrode drainpipes if used too often or left in for too long.

While some chemical drain cleaners with hydrochloric acid can dissolve hair, this method is not recommended as it can also destroy your plumbing pipes. A common DIY alternative is using baking soda and vinegar, which can help break down the clog but will not actually dissolve the hair. The best and safest method for clearing a hair clog is to remove it manually. You can use a drain snake, a straightened wire hanger with pliers to fish out the clog, or have a plumber use a professional auger for more severe blockages.

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.
