What Is An Outdoor Water Softener/ Who Is This For


Outdoor water softener is a machine that filters hard water supplies. To differentiate, water is considered as “hard water” when there is 60 mg (or more) of dissolved metals like calcium and magnesium, while it is classified as “soft water” when there is little (less than 60 mg) to no metal at all.

Through the charged resin beads, the water softener removes these metals from the water supply by attracting them away from water molecules. The now softened water passes through the machine and is supplied to the household or business requiring softened water. Meanwhile, the metals remain stuck to the resin beads and are cleaned out by the brine tank of the machine.

Outdoor water softeners are ideal for households and businesses alike. The water provided by the country may not be softened, thus making it unhealthy for drinking, and terrible for maintenance. In homes, softened water is beneficial, as it is safe for drinking, and great for plumbing, laundry, cleaning, and skincare.

In businesses, outdoor water softeners significantly increase the quality and reliability of water-based products. It improves the performance of the company since customer trust and loyalty are formed, and customers decide the success of a business.

How Does It Work

The science behind outdoor water softeners focuses on the branch of chemistry. Through the use of negatively charged resin beads, positively charged metals dissolved in the water are taken out. These metals are replaced with safer sodium ions, seeing that sodium does not obstruct the effectiveness of soaps and detergents.

Caring for outdoor water softeners is very similar to taking care of indoor appliances. Outdoor water softener installation also considers the device’s longevity of life. It should be kept from harsh weathers (such as high or freezing temperatures) and natural calamities (such as earthquakes and hurricanes). All of these factors could damage the appliance as much as other appliances. Thus, to ensure that the outdoor water softener is maintained, people have come up with two solutions.

The first solution is to bury the water softener. Most outdoor water softeners now are built to withstand being buried. By renting local augers or using an old-school shovel, anyone can create a hole for their water softener. Make sure that the water softener is placed close to the city water valve (around two feet), and that its control valve is sticking out. With this method, the appliance is both insulated and stabilized.

Another method is to place the water softener in a shed or a cabinet. There are many cabinets for sale designed for outdoor water softeners. These protect the appliance rain or shine, blocking elements that are harmful to its components. To set the cabinet properly, most people have decided to use paver blocks or concrete bases. Furthermore, some also advise adding a light bulb or a simple heater inside the cabinet to prevent freezing.

Buying Guide


There are a lot of things to consider before buying outdoor water softener, like locality, maintainability, build quality, and brand. All of these factors will help determine the functionality and efficacy of the appliance.


Always consider buying home appliances from local stores, especially ones that directly affect the supply of a household or business (e.g. electricity, water). Local outdoor water softener dealers are the best people to go to when searching for the quintessential outdoor water softener.

They are bound to have the best knowledge of the local water supply, hence being able to find the optimal outdoor water softener for the designated household/business. Buying online without proper knowledge or research of the local water supply could lead to purchasing suboptimal appliances, which is a total waste of money.


Plenty have suggested buying unbranded components, as branded ones tend to be specific to their brand only. This makes it difficult to purchase replacement parts from local hardware stores, especially when the said brand discontinues their products. Avoid this at all costs to prevent buying an entirely new appliance, which is pricier than simply purchase replacement parts.

Additionally, find something easy to preserve, meaning the parts themselves are easily accessible and replaceable. Once these parts are broken, it is suggestible to consult professionals to have the appliance serviced, rather than fixing it with DIY instructions. Ease of access makes it safer for the device, as taking everything apart is a risk for its other parts, too.

Build Quality

Build quality is crucial in scrutinizing which outdoor water softener to buy. Several may not last long as the right outdoor water softener for the home because of the weather or natural calamities. On the other hand, some are meant to be situated indoors, and some can withstand only either freezing or scorching temperatures, which could be the total opposite of local weather and calamities.


The most obvious choice when choosing brands that produce outdoor water softeners is how long they have been in the market. This speaks a lot about the brand, as it means many people believe in the quality of their products. Typically, older brands are much more reliable: the longer they have produced outdoor water softeners, the better their current products ought to be.

However, that does not mean that newer brands are not sharper than or as robust as older brands, because they may also have put in more than enough work in their products so they can be outstanding in local households/businesses. It is never wrong to analyze brands, and decide which one to choose, based on the acquired knowledge.

Can You Put A Water Softener Outside

A water softener outside might not last as long (as they are exposed to more dangerous environments) as any other appliance; however, they can still be placed there. Several manufacturers have designed their products to be able to bear harsh elements, basically allowing them to operate and survive outside for quite a time. Nevertheless, be careful before buying a water softener! Not all are made to resist the rough conditions outside your home.

Units, like the brine tank and the resin bed, are very susceptible to destruction from the cold or the scorching heat. These are essential to the functionality and upkeep of the appliance. The resin bed is responsible for the expulsion of the metals from the hard water, while the brine tank is accountable for the cleaning of the container.

Without these pieces – or others, for that matter – the outdoor water softener becomes inefficient, and at worst, completely useless. A single malfunction to any of them inside a water softener is vital to its performance. Its functionality is highly dependent on its very own components, and even the smallest of them could play a central role. So, it is essential to examine the safety of these, as taking care of each one is watching over the tank itself as well.

As mentioned above, two common ways allow the placement of water softeners outside. Depending on their build quality, they may or may not last as long as water softeners located in the safety of the inside.

All water softeners have components that are essential to the water-softening process, and all of these could be tarnished by hazardous elements that are caused by (or are) weather and calamities. It is entirely up to the home or business owners to risk putting their water softeners outside.


Getting the best outdoor water softener is essential if you’re dealing with hard water or using well water. It can treat the hardness that causes hard water problems, including plumbing damage. Using this machine, you can improve the overall quality of your water supply and prevent staining on the faucets, sinks, and plates. Moreover, the outdoor water softener is your solution if you want better-tasting, cleaner and safer water for your family. Choose one today!
