Buying Guide of Best Water Softener For Small Spaces

Test the water hardness level

The first thing you should do before any purchase tests your water’s hardness minerals.

The easiest way to do this is to purchase a hard water testing kit from your local hardware store.

It should cost between $20 and $30, but well worth the money to ensure you purchase a softener sized adequately for your needs!

The waste of time and money would be to buy a large unit only to find out it can’t handle all the water because your water hardness level is too low.

So, it is most important to know about the hardness level.

Consider the Size

The size of your home, the amount of water used daily, and how much space is available are factors that play into which unit you will purchase.

If you have a large family of 5 or more, the size 20-inch by 48-inch or more extensive may be an option for you.

If your family is smaller, you may want the size 10-inch by 21-inch or even an 8-inch by 20-inch.

They are both smaller units, but sometimes the area you have to place it in is small, so this may be a good option for you.

You will need to know your daily water usage as well.

Look Over Your Budget: Consider

Your budget plays an essential part in your purchase decision.

The initial cost, the system also incurs a high price over time in salt and electricity or water.

Before purchasing a water softener, consider your budget and how much you can afford to spend on it in the short term and, over a long time, even consider compatibility in your small spaces.

Hard water softeners can be costly, but salt and electricity typically increase the operational cost per year.

It ranges in price from $23 to $300 for a conventional softener; however, high-capacity units can cost as much as $900 or more.

Features to Look at Before Selecting a Compact Softener

Salt-Based or Salt-Free

Both types of machines will help soften your water, but they do so in different ways and with different results.

A salt-based system does not require electricity, but you must replenish the salt regularly.

A salt-free system uses a resin that requires electricity to regenerate – if you have hard water, you may need to replace this resin more often.

Dimensions

If space is an issue in your home, compact models with dimensions of only 11.7″ x 9.6″  x 27.5″ are available for under $200.

If you have enough space, you may want to consider a larger capacity model.

Grain Capacity

Capacity is measured in grains and ranges from 40 to over 100; the more significant the ability, the more pelican water softens each cycle.

Consider a unit with higher water softening capacity if you have a large household or use many appliances that require softened water.

Otherwise, smaller models will work for most homes.

Water Flow Rate

The water flow rate measures gallons per minute.

The higher the flow rate, the more hard water can be processed through your system each minute, and the fewer cycles you will have to run to soften water for your entire home.

A unit with a flow rate of 1 to 4 gallons per minute will operate in most homes, but be sure to check your water flow rate before you buy.

Salt use

Salt-based systems require the salt to be replaced every few months but can last even longer if your water contains less than 100 grains per gallon.

Salt-free systems do not use salt and do not require replacement.

Some water softeners can last up to five or six years before necessary replacement.

If you have a softener already, consider buying replacement parts to save money.

Useful Features

Some models allow you to wash your laundry in softened water, making removing dirt, dissolved minerals, and stains easier.

Many systems include valves connected to the hot and cold water supply lines, which allow you to control the water flow in your home.

If you have a large family or a home with many occupants, consider a system with an indicator light.

An indicator light will tell you when it’s time to regenerate the softener, so you don’t forget and waste salt and resin.

FAQs

Q: What is the difference between a salt-free and salt-based water softener?

A salt-free water softener uses resin to remove hardness minerals from the water and is compatible with small spaces.

They require electricity to operate and must be regenerated when full of contaminants; flow regeneration requires you to drain all water.

Salt-based systems use salt, which needs regular replacement; an indicator light on some models can automate this cycle.

Q: How often should I regenerate the resin in my salt-free water softener?

The frequency depends on how dirty your water is. If you have very hard water, you may need to regenerate it every day or two.

Q: How often should I replace the salt in my salt-based water softener?

Replacement frequency depends on how much your household uses softened water but usually occurs every few months.

Q: Can a water softener be installed anywhere in my house?

Yes, a water softener can be installed anywhere in your home as long as it is compatible with the plumbing system of that area.

You only need to consider if there are any areas where the water pressure might drop below what the softener needs before it works properly.

If this is the case, you will want to install the softener at an outlet with plenty of room for it and the pipes leading.

The installation process may vary depending on how old the plumbing is in your home.

Still, generally speaking, you hook up the supply line from the main valve to the softener and run a couple of extension hoses back to each fixture so they don’t get too complicated or dirty.

There are also many softeners explicitly designed for bathrooms and other places where low water pressure is standard.

These models usually come with dedicated lines and fittings, making them easier to install than regular ones.

Q: How do you know what size water softener you need?

You need to factor in the number of people using the water and the hardness of the water being used.

For example, if you have 3 people living in the house, your tap water is challenging (high mineral content).

Using it for drinking and cooking, you would probably need a large-capacity softener.

However, if you have 2 people in the house who drink bottled water and cook with treated tap water, you could get away with a smaller unit.

It’s really all about personal preference.

You can use this information to calculate roughly how much water you use per day.

Then add 20% extra for safety and adjust accordingly based on the estimated annual usage of your household.

If you are still unsure, you should ask your plumber to determine how much water is coming through your taps.

This way, you can make an informed decision on whether or not you need a larger or smaller water softener.

Conclusion

This guide has provided you with all the information to choose the best water softener for small spaces. So, you can easily define which is the best for you.

Your small space softener should have a high enough grain capacity to handle your household needs while still fitting in your home.

Be sure to check the water flow rate and salt use of any potential purchase.
