Experiencing a sewage emergency in your basement can be incredibly distressing. It’s not only unsightly, but it can also pose potential health risks and damage your property. But don’t fret! If you are in this unfortunate situation, we’ve got you covered. 

Today’s blog post from our team at Full Speed Plumbing is going to arm you with helpful tips to tackle this messy problem head-on. From identifying the signs to prevention strategies to cleanup processes, we’ll guide you through each step. Stay with us, and turn this daunting task into a manageable one.

5 Causes of Sewage Backups in Basements

If you’ve recently experienced a sewage backup in your basement, you may be wondering what caused the issue. Although it’s hard to pinpoint the cause without professional assistance, one of the following issues is most likely responsible for the backup:

  1. Clogs: Much like your drain pipes, your main sewer line can also become clogged, leading to a blockage. A sewage backup in your basement floor drain can occur when items that are too large or not easily broken down are flushed down the toilet or dumped down the sink.
  2. Tree Roots: Tree roots can invade and block your sewer lines, causing a backup. They can create cracks in the pipes or grow into the pipes, leading to blockages and, eventually, backups.
  3. Damaged Sewer Lines: Old, corroded, or collapsed lines can obstruct the flow of wastewater, leading to a backup. Homes built over 30 years ago may still have cast iron pipes or clay pipes, which can break or collapse over time.
  4. Heavy Rainfall: During heavy rain, the water volume can exceed the sewer system’s capacity. The excess water can then back up into the lower areas of your home, like your basement.
  5. City Sewer Issues: If the public sewer system in your city or municipality is having issues or is under maintenance, it could lead to a backup in your basement. This is usually a problem beyond your control.

9 of the Top Tips for Dealing with Sewage Backups in Basements

Are you having a hard time dealing with the sewage issue in your basement? Feel free to try out one (or more) of the following tips:

  1. Identify the Source of the Problem: Before you start dealing with the backup, it’s crucial to identify the source of the problem. Is it a clog? Or is it due to heavy rainfall? Understanding the source can help in applying the most effective solution. For instance, if tree roots are the culprit, removing them would be the best course of action.
  2. Equip Yourself Properly: Always make sure you have the right personal protective equipment (PPE) before tackling a sewage backup. This includes rubber gloves, boots, goggles, and a mask. Remember, you’re dealing with wastewater that can contain harmful bacteria and pathogens.
  3. Switch Off Electricity: If the backup is substantial and has reached electrical outlets or appliances, switch off the electricity immediately. Water and electricity are a dangerous pair. It would be wise to consult an electrician if you’re unsure.
  4. Remove Water and Solid Waste: Once safety measures are in place, remove the water and solid waste. A wet/dry vacuum can be helpful in this situation. Dispose of the waste in accordance with local regulations.
  5. Clean and Sanitize the Area: After removing the water and waste, thoroughly clean the area using a solution of one part bleach to ten parts water. Doing this helps in eliminating harmful bacteria.
  6. Dry the Area Thoroughly: You can use fans, dehumidifiers, or heaters to dry the area completely. This helps prevent mold and mildew from forming.
  7. Inspect and Repair Damaged Items: Inspect your belongings and decide what can be salvaged. Some items might require professional cleaning. Remember to dispose of unsalvageable items properly.
  8. Prevention is Key: Once the immediate problem is addressed, work towards prevention. Regular maintenance of your sewer lines, avoiding flushing inappropriate items, and installing a backwater valve can help prevent future backups.
  9. Contact a Professional: If the problem is too large to handle yourself, or if you’re unsure about any part of the process, don’t hesitate to contact a professional plumber. They have the training and equipment to deal with sewage backups safely and effectively, ensuring your home is safe and clean. Remember, it’s always better to be safe than sorry.
