Most sewer and septic pipes are protected from freezing in cold winter weather by the soil and vegetation that insulates them in the ground. Even in cold climate regions, septic pipes don’t normally freeze. However, there are some circumstances which can make it possible for these underground pipes to freeze and cause problems for the homeowner. Here are a few common causes of freezing septic pipes:
- No ground cover. Newly installed septic pipes which have no vegetation above them have less insulation, leaving pipes susceptible to freezing.
- Cold weather with no snow. A deep frost with no snow for insulation can freeze the ground and septic pipes, in some cases.
- Irregular use. Septic systems that are not used regularly, such as a vacation cabin, are more likely to have pipes freeze. This can also occur in homes which are used less frequently than the system is designed to handle.
- Dripping plumbing or furnace. If plumbing is dripping small amounts of water, or there is condensation from a furnace or dehumidifier, this trickle of slow water can freeze inside the pipes.
- Cold air. If an inspection cap is left open or is cracked, it can allow cold air into the system that can freeze septic pipes.
- Poor drainage. Septic pipes that are not inclined or have settled may not drain correctly, causing water to pool and freeze.
A frozen sewer or septic pipe will usually cause a backup into the home’s plumbing, requiring the help of a septic professional. If the problem is not fixed, the septic pipes will continue to freeze and can cause more damage to the system in the future.
