What is an Outdoor Water Softener?

A water softener for outside use is an appliance that utilizes salt to remove the hard minerals and produce treated water that you use at home. 

After the salts dissolve in water, they’ll bind themselves to impurities such as calcium and magnesium to eliminate them from H20 molecules.

It can be a reasonable solution for businesses and homes. The water from the countryside is not soft, meaning it is unfit for drinking and makes maintenance difficult. 

Softened water is safe to drink in the home and less harsh on plumbing, washing machines, cleaning products, and your skin.

What is the Process?

The system utilizes negatively charged resin beads; positively charged metals that dissolve in water are filtered out.

These metals are replaced by faster sodium chloride ions, recognizing that sodium is not hindering the efficacy of soaps and detergents.

The installation of outside water softeners also examines the device’s longevity.

Cleaning outside water softeners is similar to the care you give appliances in the indoor environment. 

It must protect from extreme weather (excessive or freezing temperatures) and natural disasters (such as hurricanes and earthquakes).

These elements could harm the appliance in the same way as other equipment. Therefore, to ensure that the softener‘s performance is maintained, the experts have developed two strategies.

The most obvious solution is to put the softener on the ground. Water softener for external use is compatible to last when placed in a sandbag.

Anyone can make an opening in their softener water by renting local augers or using an old-fashioned shovel.

Another option is to put the water softener inside the form of a shed or cabinet. 

A variety of cabinets are available for sale designed specifically with outdoor systems

Some also suggest using lighting fixtures or a simple heater in the cabinet to stop freezing.

Indoor vs. Outdoor Water Softener

Outdoor and indoor softeners for water use the same ion-exchange method to soften water. However, outdoor units should be fit to withstand outdoor elements.

Outdoor models are usually more expensive than indoor models and last around five years on average. 

Indoor units must also be able to handle a volume in line with the size of the home because of their smaller footprint and greater need for water filters.

What to Look Out For When Buying An Outdoor Water Softener?

A suitable water softener cannot only perform a great job of taking minerals from the main water supply. There are other elements to be considered before purchasing a product.

It can be a difficult task, but it’s not complicated. You can make an informed choice if you can understand your requirements and compare them with the points we have in the following list.

High Build Quality

It is vital to have an exterior water softener with sturdy construction. There are numerous elements they need to weather. 

Check that the softener you’re looking at is suitable for outdoor installation. If it is not, you’ll end up with a water softener that will damage within months.

Grain capacity

The grain capacity of an outdoor water softener is the number of crystals it can hold before they need to be replaced.

A softener with a high grain capacity will last longer and perform better than one with a lower capacity. You should calculate the perfect grain capacity for your softener:

US map to know hard water level
Source:- Pressroom

NOTE: – When you have water hardness in MGL or PPM, you can convert it into GPG by dividing 17.1.

For Example, 170PPM of hardness equals 9.9 grains per gallon of hardness.

And with iron presence, you need to add 5GPG for 1PPM of iron when choosing the softener size.

For Example: If you have 17GPG with 3PPM of iron. You need to select 32GPG sized system.

3PPM of iron X5=15GPG of hardness + 17GPG = 32GPG.

With the help of this table, you can quickly know the softener’s grain capacity, which will be perfect for your need (swipe right to see all of the information).

Opt for a system that has parts that are easily accessible and replaceable. It makes it easy to get replacements from your local hardware store. 

It will be an immense favor and prevent you from purchasing the entire unit, which will cost more than buying replacement parts.


When evaluating brands, check their credibility by looking at how long they’ve been on the market. It will show how many people trust their products. 

Furthermore, older brands are more reliable because they’ve been making water softeners for longer.

They will likely upgrade their models to be more effective following years of continuous advancement.

There are, however, brand newer ones that offer quality products. It is essential to decide by analyzing different brands.


When putting up an outside water softener, ensure that the Temperature doesn’t fall below freezing or get too hot.

If the weather in your area isn’t suitable for installation outside, you could always choose a location with shade or even bury it beneath.

Contact the local hardware store to find out which model is ideal for your family, considering the variety of weather conditions.

Cover and Closure

In addition to prior elements, an enclosure for your outside water softener will be the most effective way to safeguard your equipment. 

It will ensure that, no matter what, the weather outside your system will be safe and secure. 

There are many choices available in the market based on the model and quality.

Expect to spend between $50 and $150. Be aware of the dimensions of the unit before buying an enclosure.

We’ve covered a few crucial elements you must carefully consider before choosing the best water softener. 

Keep these in mind when you look to find a system that’s ideal for your house. Make sure you bring the list along with you.


The cost of an outdoor water softener will vary depending on the model and included features.

Generally, more expensive water softeners tend to have features such as a larger capacity tank or faster regeneration time.

Some softeners look costly, but their features justify the price.

What Kind Of Water Softener Are They Able To Be Installed Outside?

Two kinds of water softeners you can install inside or out. They are salt-based ion exchangers as well as salt-free conditioning.

Salt-Based Ion Exchangers

Salt-based water softeners, also called Ion exchange systems, utilize Ions to remove calcium and magnesium from drinking water.

The soft water systems comprise two tanks that are a brine tank as well as the resin tank

Many people believe salt-based softeners are the most effective solution for water softening since they remove hardness ions from the main water supply.

The brine tank is a storage place for salt (sodium chloride) introduced into the resin tank via ion exchange. 

The sodium ions substitute for the magnesium and calcium ions present in the hard water. And when the mineral tank is overflowing with these minerals, they are flushed out by a regeneration process.

You can know about your water hardness level with the help of this table:

Degree of hardnessCalcium carbonate: Milligrams per literCalcium carbonate: Grains per gallon
Soft0 – 600 – 3.5
Moderately hard60 – 1203.5 – 7
Hard120-1807 – 10.5
Very hardMore than 180More than 10.5

Salt-Free Conditioners

Salt-free conditioners do not require salt to soften water. They do not technically soften water in any way; instead, they employ the process of Template-Assisted Crystallization (TAC) to “condition” water.

It implies that calcium and magnesium aren’t eliminated from the water. Instead, they’re altered within the TAC media tank.

The softener creates a crystallized outer layer that hinders them from adhering to appliances and pipes.

Salt-free water softeners consist of one tank, making them a little simpler to set up and maintain, mainly since they don’t require salt to run – that’s one less thing to think about.

Can I Install A Water Softener Outdoor?    

The climate and Temperature are the most critical factor, especially when you live in a nation region that doesn’t see frigid temperatures and doesn’t have a movable basement (or any basement at all).

The possibility of an outdoor setup might be possible, not only feasible. However, it is also preferable.

The requirements for outdoor water softener installation are usually similar to those for the requirements for an indoor facility.

  • You need to install a water softener near the water entry point of your home or outdoor faucets. It can be close to a water meter or a pressure tank if you’re using well water.
  • Power should be available close by because the valve’s controller requires the ability to run all its cycles- the near an energy source, the more efficient.
  • There needs to be a way for water to drain out the hardness minerals generated near safely.
  • You must place it in a location that is easily accessible. Be aware that you’ll have to add salt for softening into your brine tank.
  • There should be enough space. It may seem like a no-brainer. However, there must be ample space surrounding the installation site to allow plumbing to run.

Alongside those fundamental needs, there are other aspects that outdoor installation might require. 

For instance, it must always avoid direct sunlight because it could cause harm to the mineral tank and controller over time. 

Professional installers often choose to set up outdoor units underneath lean-to or in the form of a small storage shed.

How Do I Find The Effective Water Softener Cover To Use Outdoors?

Suppose you are looking for an enclosure to shield the system from the worst conditions in winter. In that case, Covers & All Store is the most effective water softener cover.

It is made of water-proof high-quality synthetic fabric, is snowproof, and is 100% protected from UV light.

Perfect to shield the water softener during its use of it, it’s ventilated. It has air pockets on the sides to assist in air circulation.

This cover for outside water softeners comes in different sizes and is compatible with all water softeners available. 

If your unit doesn’t have a regular-size cover, it is possible to request an individual cover. 

How to Winterize The Outdoor Water Softener?

If you reside in a more temperate climate and the weather isn’t freezing, you won’t have to freeze the softening of your water.

But, if the softener is in a location where it is likely to freeze, you should prepare it for winter to safeguard it from damage.

If you reside in a colder climate and wish to continue using your water softener all through the winter months, put it inside or in a well-insulated enclosed enclosure.

To prepare your softener for winter, take the instructions below.

  1. Find the main water valve and close it to stop the softener’s water flow.
  2. Use a faucet in your home to let the air out within the system.
  3. Step up into the bypass valve, or close the outlet and inlet valves (depending on the outdoor water softener model). Now you can turn off the water if you want to supply water to the rest of the home.
  4. Unplug the transformer for the water softener from the outlet on the wall.
  5. Remove the adapters or bypass valve from the softener. Then take it off and take the brine well out of the way.
  6. The brine well should be flipped upside down to let the water drain, and then gently set the softener onto the wooden support or on the floor to rid the brine tank.
  7. After draining all the water out of the system, cover it with a water softener. Please keep it in a closed space.


Can water softener salt be stored outside?

You can store it outside but in a cool place and keep it away from direct sunlight.
The best way to do this is by putting the salt (potassium chloride) into an airtight container with a lid.
You should also ensure that the container has no holes or cracks, as these will allow moisture to get inside.
If you are worried about your salt getting wet, you could put some plastic wrap over the top of the container.
This will prevent moisture from entering but still allow the salt to breathe.

Where do you plan to keep the salt for water softening?

If you’re deciding where to put an outside water softener, consider where you’ll be keeping the salt bags you’ll require to run the softener. 
You don’t want to transport the loads to the other side of the property.
Any precautions you follow to install a water softener outdoors must cover it to shield your investment from weather and other elements.
A simple shed for utility will aid in protecting the water softener as well as offer a convenient place to store the salt for water softening which the system will require.

Can the sun damage a water softener?

The sunlight in its entirety shouldn’t cause damage to the media tank of an outdoor water softener; however, the UV rays may result in the structure of the fiberglass resin weakening and shrinking.
The same thing can happen to the plastic and other composite materials utilized in the control valve for water softener valves if they are expos to sunlight for some time.

Can you bury a water softener if it is outside?

The placement of a water softener a few feet deep in the ground will help keep freezing since it assists in insulating a portion of the tank with the ground.
It is a standard procedure when installing a water system outside, which is said to aid in helping to keep it from freezing.
In burying the water softener in-ground, you guard against theft since it will take some time and noise to dig out and take the system off.
While a water softener is typically only placed in a few feet of soil, it is essential to ensure that it should not bury near any plants or trees.
The tree roots generally do not extend through the water softener’s fiberglass tank. Still, they may grow more tightly within the tank.
It makes it extremely difficult to repair or replace the system when needed.
A landscaping fabric may aid in protecting the bottom of the softener after you have buried it, and putting the dirt around it can help stop pockets of water from forming.


The buying process for the most effective outdoor water softener requires extensive study and consideration.

But, if you’re looking to address the hard water issue in your home effectively, you must locate high-quality equipment that will handle all problems.

Reading reviews and keeping track of the essential factors to consider can significantly increase the chances of securing an excellent outside water softener. 

Additionally, it would help to think about your preferences and water consumption to make a wise choice. 

We hope you can buy the best unit suitable for your home with the details we have given you.
