Things To Keep In Mind When Installing Your Water Softener Outside

  • Temperature: Water softeners shouldn’t be exposed to extreme temperatures as it can affect their operation and performance. Make sure you choose a spot not in direct sunlight or too far away from heat sources, such as furnaces and air conditioning units.
  • Direct Sunlight: Most water softeners must be placed in a spot, not in direct sunlight. This is because the sun’s heat can damage some components, such as plastic valves and tubing. If your installation area has too much direct sunlight exposure, you may want to consider putting up an awning or other cover to protect it. Alternatively, you may install a water softener in the basement or garage if your house has those options.

  • Humidity: Considering the humidity level when installing a water softener outside is important. Humid conditions can cause corrosion and other damage over time to the parts of a water softener, so it should be installed in a well-ventilated area with low humidity. If your home is in a humid climate, installing the water softener indoors may be best.
  • Weather Considerations: Installing a water softener outdoors also means being mindful of the weather conditions in your area. Depending on your location, you may need to disconnect it during heavy rain or snowfall. Make sure you check the manufacturer’s recommended operation temperatures, as well. If your area gets cold in the winter, you will want to ensure that the water softener is insulated properly and adequately protected from temperature extremes.
    Weather Considerations
    Weather Considerations
  • Easy Access: Some people install their water softener outdoors because it is easy to access and maintain. Outdoors, the unit is more exposed to the elements, so there is a greater need for regular maintenance. The water softener outside will also make it easier if you ever need to replace parts or add salt or other additives.
  • Drain: Before installing a water softener outside, consider the drain. Ensure you have an outlet near the unit that is high enough to allow gravity drainage. It’s also important to ensure the drain hose is insulated properly if your climate has regular temperature swings; otherwise, the water in the hose can freeze and burst.
  • Being Near The Main Entry Point Of Water: You must consider that the softened water needs to be taken into the house. Therefore, your softener must be installed near the main entry point of the water.
  • Access To Power Source: An outdoor water softener installation is possible, but it would need to be in an area with access to an electrical power source. Since most water softeners are electrically powered, they are unsuitable for installation in areas without an available power supply.
  • Use A Water Softener Cover: If you install your water softener outside, it is best to use a waterproof and UV-resistant cover to protect it from the elements. This will help ensure it remains in good working condition for years. Additionally, some covers come with built-in insulation, which can help keep your water softener running even more efficiently. Make sure to check with the manufacturer of your water softener for specific cover recommendations.
