Because of its placement, it might seem like your septic system is easily susceptible to freezing. Fortunately, the unique pitch design of the pipes and the release of methane gas inside the tank allow the setup to mostly withstand winter’s wrath. However, when temperatures plummet, there are certain situations that could result in a freeze up and require septic repairs. The following guide breaks down what to expect so that you can avoid this scenario.

How Can You Prevent Freezing?

Using the system frequently will reduce the ability for water to freeze because there's constant flowing water. Also, regularly inspect toilets, faucets, and visible plumbing for signs of a leak. 

An ongoing leak can create a constant low flow of water into the pipes connecting to the septic system. Since the pressure isn’t high enough to keep the liquid moving, it can easily freeze and eventually block the pipe. 

If your tank is located underground, adding mulch over the area will provide insulation and prevent frost from penetrating the ground. Snow can also act in this manner as long as it remains fluffy and not compacted or frozen. Avoid walking or driving over the region where the tank, pipes, or drain field is located to prevent pushing down the frost and potentially shifting or sinking the drainage pipes. 

What Can You Do if the System Freezes?

It’s usually easy to tell if the setup is frozen because the toilets won’t flush and the sinks and washing machine won’t drain. If this happens, call a septic repair technician immediately to identify the freeze point and correct the issue. In the meantime, do not add antifreeze to the pipes, start a fire above the area outside in an attempt to thaw the ice, or let water run continuously since this will overload the system.

The technician will use cameras to determine where the freezing is occurring and if septic repairs are needed. They might also use high-pressure jets to unfreeze the piping and add heat tape to the septic tank to regulate the temperature. 

If the drain field cannot be defrosted, it won’t be able to accept liquid until it naturally thaws. In this case, the septic tank would have to become a holding tank and will require septic pumping regularly.
