Four Tips to Protect Your Septic System from Freezing Temperatures

November 16, 2018 Published by Leave your thoughts

We’re starting to see shorter days, dropping temperatures and, in some places, snow. If you were trying to hang on to any remnants of summer, it’s time to let go and start preparing for winter. While furnace checks and sealing windows and doors are a given on any winter preparation checklist, have you thought of adding your septic tank to that list? As a septic tank service in Mora, MN, we get a lot of emergency calls in the winter from people who are experiencing the effects of a frozen septic tank. Most people don’t realize that, under the right conditions, their septic system can freeze, wreaking havoc. If you want to protect your septic system from freezing this winter, we’re going to give you a few tips from the experts.

How does a septic system freeze?

Before we get into prevention, let’s talk about what causes a septic system to freeze in the first place. Believe it or not, snow is actually good for preventing freezing. Snow is a natural insulator for your septic tank. If there are several inches (or even feet) of snow over your tank, even the coldest temperatures shouldn’t be able to freeze your tank. However, if there’s no snow, but temperatures are far below zero, that is when your septic tank is susceptible to freezing.

How can you keep your septic tank from freezing?

Now that we understand under what conditions your septic tank can freeze, let’s look at steps you can take to keep this from happening:

  • Insulate: If there’s no snow on the ground to help insulate your septic tank in frigid temperatures, you can cover the pipes, tank and soil treatment system with about 8 to 12 inches of mulch. You can use leaves, straw, hay or any other loose material that is dense enough to stay in place but won’t become too compacted.
  • Keep it flowing: Keep water flowing through the system so it never sits long enough to freeze. You should not, however, keep water running all the time. You can change your laundry schedule to cross over several days instead of just one, take hot baths and use your dishwasher daily. Make sure to use hot water. The hotter the water, the less likely it is to have time to freeze.
  • Get a house-sitter while you’re gone: Winter is the time for winter break vacations and visiting family. If you are going to be away from home for an extended period of time during the winter, ask someone to come in and run hot water in your home regularly while you are gone.
  • Stay on top of your maintenance: Be sure to fix any plumbing issues in your home. Leaky appliances and plumbing fixtures can cause problems if they are providing a slow flow of cold water to your septic system.

By following these simple tips, you can avoid the cost and hassle of your septic tank freezing this winter. If you do run into an emergency, don’t hesitate to call A & A Septic Service LLC, your trusted septic tank service in Mora, MN!
