A water softener (a.k.a. water conditioner) system is the most effective type of whole house filtration system to remove calcium and magnesium from water – minerals that make water “hard.” While hard water and the responsible minerals are not, in themselves, unhealthy, they do cause problems for people who bathe in and wash with it, to the plumbing, and a number of appliances. If the water that you get in your property is moderately hard (approximately 3.5 Grains per Gallon or GPG) or higher, then you may want to consider the benefits of a water softener. Conditioning of “softening” your water potentially bring considerable cost savings as well as the prevention of problems caused by hard water. However, if your property is one of the millions relying on on-site dedicated septic systems, you will need to take your sewage treatment facility into consideration in making your choice of water softener.
What water softener is best for septic systems? There are two main types of water softeners: demand-initiated regeneration (DIR) and timer-based systems. A DIR water softener measures your water usage and average water hardness and determine when to regenerate. Timer-based systems, on the other hand, operates on a predetermined timeframe that may or may not be accurate. This is why DIR water softeners are considered more efficient as these conserve water, energy, and salt use. DIR water softeners are considered as the best systems for homes with septic tanks for several reasons: First, the amount of water discharged by a DIR system is equivalent to a load of laundry, meaning it is easily within the thresholds of a septic system’s capacity. Second, because a DIR softener only regenerates when necessary, the system is not overloaded with backwash of softener. Third, the discharged solution of a DIR system has a greater ratio of calcium and magnesium ions to sodium. High amounts of calcium and magnesium actually help improve the absorption time of treated wastewater by the drainfield. Finally, water softeners also help homeowners consume up to 50% less soap and reduce overall water usage. If you own a septic system, you would already know that conservative water usage goes a long way in keeping a septic system healthy for a long time.
If you already own a water filter or you only need a water softener to remove scale build-up and the staining properties from hard water that you get, keep on reading for our recommendations of the best water softeners and salt-free water conditioners. If you look closely at each brand/model, you will find that the different manufacturers offer the systems in various sizes and with different options.

The Effects of Hard Water
Some household areas are known to have “hard water”. High concentrations of calcium carbonate, magnesium, and iron are common in the water of about 85% of households in the US. While not dangerous, hard water does pose a number of concerns:
Scale build-up. Scale is the white, crusty build-up of hard minerals you often see on faucets, in pipes, and in some appliances. This build-up of scale can cause corrosion, inefficiency, and shortened lifespan of appliances over time. This also leaves water spots on dishes and in showers. If iron is likewise present in your water, scale presents in a pink, orange, or red color.
Inefficient home appliances. Hard water needs more energy to heat and so water-utilizing appliances (such as your water heaters, dishwashers, and washing machines) are rendered less efficient when there is a build-up of scale on their heating elements. Over time, this additional wear may decrease the lifespan of your appliances by up to 50%.
Impeded soap action. Hard water hampers soap from lathering sufficiently, which means you use more soap that will not clean nearly as efficiently. Cleansing, bathing, and washing laundry and dishes will thus require considerably more soap.
Dull laundry. Hard water and its scale deposits will affect the ability of your washing machine to properly clean your clothing. Whites and colored laundry may appear dull and fabrics can feel stiff or scratchy. As earlier mentioned, more detergent will be needed just to counter the effects of hard water.
Hair dullness and damage. If you have hard water, chances are, you end up with dry and/or limp hair from all the build-up of hard water minerals on your hair. These hard water minerals can also combine with the natural oils found on your scalp, leaving it feeling greasy, or even dry and flaky. If you notice a strange orange or green tint to your hair, this can be caused by hard water combined with the chlorine in city water. Also, hair color and highlights will fade more rapidly in hard water conditions.
Dry skin. High levels of minerals in water can be harmful to your skin, leaving it dry and listless. Hard water can strip off the skin’s natural oils and even clog up your pores. Sufferers of eczema or psoriasis may also experience increased irritation. If you live in a property with hard water, you need to work harder to clean, condition, and moisturize your skin.
Poor-tasting food and beverages. Hard water will greatly affect the taste of the food you cook and the beverages you prepare (like your coffee, tea, and juice). If you have softer (or treated) water, you can preserve your food and drinks’ bolder, more pure flavors.
How Water Softener Systems Can Affect Your Septic System
The “hardness” of water in a locale is caused by high concentrations of minerals, specifically calcium and magnesium. Hard water has a number of disadvantages for any household. Again, hard water, per se, is not dangerous, but it can be an irritant, both literally and figuratively, as discussed in the previous section. Installing a water softener is an easy solution if what you have is hard water in your location.
A water softening system will help definitely help address issues that hard water brings with it. Water softening systems involve a resin bed that swaps the calcium and magnesium for sodium ions. The result such process is softened water, which will flow in place of the hard water that you may naturally be getting.
When the system’s resin bed is filled with the “hard” minerals, it begins a regeneration cycle. Brine, or high-sodium water, passes through the resin bed. The brine provides sodium ions that will replace the hardness ions. Eventually, the brine drains, taking the hardness ions along with it.
If your property relies on an on-site septic system, you would understandably be wondering how this water softening process can impact your septic system. You could be concerned that the brine is harmful to your system’s natural bacteria. Or, perhaps you’re concerned about the additional liquid entering your septic tank. Do the hardness ions disrupt a drainfield’s absorption?
All understandable questions, but you can rest assured. The good news is water softeners do not pose a problem for septic systems. On the contrary, water softening systems actually aid septic systems. Research has shown that softened water can promote the growth of essential bacteria. This bacterial growth, as we all know, will only enhance the efficiency of any septic system.
Another study conducted by the Water Quality Research Foundation likewise found that the brine from water softeners do not cause overflowing in a septic system. The brine’s high levels of calcium and magnesium, in fact, helps solid wastes settle to the bottom (as they should in a well-functioning system), thus reducing the risk of flooding.
Salt-based vs. Salt-less Water Softener Systems
Should you install a conventional water softener system that utilizes salt? Or should you opt for a newer salt-free water softener? Let us help you differentiate the two types of water softener systems.
Traditional salt-based water softeners operate by utilizing a process called ion exchange to turn hard water into soft water. The minerals (calcium and magnesium) that cause water hardness are trapped in a resin and then periodically flushed out during automatic regeneration (cleaning) cycles. The hard mineral ions are replaced with sodium ions from the salt that is add to the system.
These conventional systems are effective in treating very hard water. However, you will need to routinely replace the salt and these systems require an electrical connection in order to operate. They are also known to waste some water when running the regeneration cycles.
Salt-free water softeners (also known as water conditioners), on the other hand, are the more modern alternative. These systems operate through a process called Template Assisted Crystallization (TAC) to convert the hard minerals found in water into crystals that do not lead to scale build-up. Salt-free water softeners don’t actually remove the hardness – they merely change its form. Despite this difference, salt-less systems are still referred to as a type of water softener system because they diminish, if not eliminate, the effects of hard water.
Salt-free water softeners do not require any salt, maintenance, or electricity to operate, which makes them much easier to manage and are known to be a “greener” alternative to the traditional salt-based systems.
While salt-free systems are known to be more cost efficient, easier to maintain, and better for people who are sensitive to extra salt in their diets, these systems are not as effective as are traditional salt-based systems in treating very hard water.
Whether you choose salt-based or salt-free systems, it still pays to remember that these systems only filter out scale-producing minerals and some iron. If there are other contaminants present in your water, you may have to consider combining a water softener with a whole house water filter, which is a more comprehensive water purification system. You could also install an under-sink reverse osmosis system that will be more effective in removing other contaminants and the sodium coming from your water softener system before you drink or cook with your tap water.
We have learned that hard water may bear some ill effects on your hair, skin, diet, laundry, dishes and is not great on appliances and plumbing and anywhere else that water evaporates. But before you decide on a water softener system for your property, do consider its effects on your septic system, as well. There are several factors that can impact a septic system’s ability to run efficiently and cleanly, of course. The good news is an undersized septic tank or excessive use of cleaning products is more likely to disrupt the normal operation of your system than a water softener would. And if you are running a water softener in your property, do consider the regeneration style and age of the water softening system you have, as it might be time for an upgrade. In general, timer-based water softeners and systems that are upwards of 10 years old are considered obsolete and past their prime. If your property relies on a septic system, you definitely will want a water softener system that is efficient. You definitely would not want a water softener that goes into regeneration cycles too frequently as this might overload your septic. But more than your choice of a water softener system, the most vital thing remains: your septic system should be well-maintained, subject to considerate usage, and periodically pumped.
