How Winter Weather Impacts Your Water Softener (and What You Can Do About It)

Winter can be a cozy time of year in Virginia, even when temperatures drop to their lowest. But just because it’s toasty in your living room doesn’t mean your water softener is protected. Here’s what you need to know about how to protect your water softener in winter weather.


What Happens to Your Water Softener During the Colder Months

Softeners are often placed in areas where temperatures fluctuate more frequently, such as garages or utility closets. This means your softener can be subjected to much lower temperatures than other equipment, which puts it at risk for a range of issues. 


For example, water in the softener’s tank or pipes may freeze. The pressure that builds as a result can cause cracks or leaks, leading to costly damage to both the system and potentially your home.


How to Protect Your Water Softener in Winter in 3 Key Steps

Safeguarding your unit is easier than you think. Here are three crucial yet simple steps to winterize your water softener:


1. Insulate Vulnerable Areas

Insulating the space around your water softener is one of the best ways to protect it. Doing so also helps keep the rest of the space more comfortable and saves on energy expenses. If you don’t want to add insulation, you could always use a small temperature-controlled space heater near the unit instead.


2. Consider Using Bypass Mode

Homeowners often travel during winter, whether it’s for holidays or just to get away from the cold for a spell. Either way, you’ll want to take special precautions if you’re turning your heat down for a significant amount of time. 


This might include turning your water softener on “bypass” mode and draining it. It’s a more involved step, but one that can help prevent it from freezing while you’re gone.


3. Prepare for Winter by Pre-Checking for Issues

Prevention is important for protecting appliances like your water softener. Do a quick visual inspection of your water softener. If you notice any issues with connections or see leaking, call a specialist for a fix. 


Repairing issues as early as possible can help you avoid costlier problems down the line.
