Where Can Water Softeners Be Installed?

One of the most common questions our experts get asked is about where they can install water softeners. Many people assume home water systems are installed under the sink, but this isn’t always the case. In fact, an installation expert, like one of our local experts, will discuss with you the best place to install your water softener, inside or outside.

Important things to consider when installing a water softener

There are several important features that the location where your water softener is installed should have. It is crucial that wherever your water softener is installed it is easily accessible, as you will need to add salt to the brine tank to ensure that it continues to provide soft water.

It should also be on a flat, level surface near the entry of the water supply to your property, and have safe drainage options. Because a water softener uses some electricity for the smart technology and to control the regeneration process, it should also have access to a power supply.

If at all possible, it is best to avoid installing water softeners in places that will experience freezing temperatures. However, it is important to install yours in the best place for your home. This could be a number of places, from under the kitchen sink to the garage to the outdoors.

Basements are often considered to be good locations for water softeners. This is because they are large enough to contain and access a softener of any size, as well as other necessary water treatment equipment. This may also be where your water heater is, so keeping your equipment centralised can help with diagnosing and fixing problems, as well as with the maintenance of equipment.


Garages are another reasonably large space for water softeners that tend to be easier to access than basements due to the absence of stairs. This means that you will have to put less effort into transporting the salt to the softener, and it will be accessible for you if it requires maintenance.

Crawl space

Our compact water softeners are perfect for small crawl spaces, so they should be accessible even if they’re hidden away in a cupboard. Crawl spaces help your water softeners take up less room. They also often provide access to pipes without taking up too much space or having to do additional plumbing work to ensure that everything is connected the way it should be.

Utility room

Utility rooms give good access to plumbing systems, although innovative storage solutions may be needed to ensure that your water softener fits into the often small space. They’re fantastic solutions if your home doesn’t have a garage or a basement, and are easily accessible for maintenance and salt replacement. You might even already have a place to store the salt needed in your utility room!

Storing water softeners outside is possible. It may even be the best option if your home is limited in space near the entry point of the water supply from the outside. However, there are also a few things to consider when it comes to outdoor installation. The softener must be protected from the elements, including freezing temperatures and direct sunlight, as well as insects, vermin and vandalism.

How do I protect my outdoor water softener?

There are protective casings you can find that will help protect your outside water softener from the elements. You can also include extra protection like placing part of it in a small hole if necessary. You should also ensure that it isn’t in direct sunlight as the UV rays from the sun can cause deterioration, reducing efficiency. Our experts are able to fully recommend what you will need when housing your water softener outdoors, so there’s no need to worry about.

Water softeners are most often installed inside a house, whether that’s in the basement, kitchen garage, utility room or crawl space. However, it’s also possible to install water softeners outside. They need to be protected from the elements, extreme temperatures and direct sunlight, but a water softener installation expert can advise you on the necessary measures for your outside water softener.
