What Is An Outdoor Water Softener?

An outdoor water softener is a device that uses salt to clean the hard minerals from your home’s water. Once these salts are dissolved, they’ll attach themselves to impurities like calcium and magnesium in order to remove them from the H20 molecules.

Outdoor water softeners are an affordable option for households and businesses. Country water may not be softened, which means it is unsafe to drink and makes maintenance difficult. In homes, softened water is safer for drinking purposes and easier on plumbing, laundry machines, cleaning solutions, and your skin.

How Does it Work?

Outdoor water softener units are typically installed on your property, making them perfect for rural areas that lack city water. A hose is then attached to the unit’s intake valve and run across a nearby stream or lake where it can draw in untreated water to be softened through a process known as ion exchange.

Outdoor water softeners are made just like other appliances. They are made to withstand the natural elements and should be cared for as one would do with any other appliance.

Outdoor water softeners tend to wear out more quickly than other home appliances, but they can still be installed outside. Many manufacturers design their products to resist harsh environments and last a long time in an outdoor setting. Still, it's important to research the specific model before buying and installing your appliance outside.

Indoor vs Outdoor Water Softeners

Both indoor and outdoor water softeners use the same ion-exchange process to soften water, but outdoor units must be able to withstand outside elements.

Outdoor models are typically more expensive than indoor ones, and they last about five years on average. Indoor units should also have a high capacity that matches their home size because of the smaller space and the greater demand for water.

Current Trends in Outdoor Water Softeners

A recent trend has been to install outdoor units on higher ground so that they are more accessible, but also safe from flooding or other natural disasters. Additionally, many homeowners have moved their softener outside once they realized it can still work by just needing an external connection and can save room inside your home.


Outdoor water softeners are a wise investment for homeowners who need to maintain the appearance of their home or want an aesthetic advantage. Water softeners are a great way to produce soft and clean water for your home, but also be cost-effective. 

Softeners are recommended for families with children or pets because they reduce the number of minerals in their hair and skin which can cause irritation. Overall, an outdoor unit is a great way to save space inside your house while producing quality water outside!
