Hard water may not seem like a major issue—until you notice chalky buildup on your faucets, soap that won’t lather, and dry skin or hair after every shower. Over time, these small annoyances can become bigger problems, like clogged pipes and early appliance failure. That’s where a water softener system can make a difference.
In this guide, we’ll explain how water softeners work, compare different types of systems, and help you choose the best water softener system for your home. Whether you have city water or a private well, the right system can improve your water quality and protect your home’s plumbing and appliances.
What Is Hard Water and Why Should You Soften It?
Hard water is water that contains high levels of the hardness causing minerals calcium and magnesium. While these minerals aren’t necessarily harmful to your health, they can cause plenty of trouble around your home.
Symptoms of hard water you might notice:
- White spots or streaks on your glasses and dishes
- Soap that doesn’t foam or clean effectively
- Dry skin and dull, lifeless hair caused by hard water stripping natural oils
- Limescale buildup around plumbing fixtures, faucets, and drains
- Reduced water flow and efficiency in water using appliances
Over time, hard water can lead to more serious issues, like higher energy bills and shorter lifespans for dishwashers, washing machines, and other water using appliances. A water softener system helps eliminate these problems by removing the minerals responsible for hard water.
How Do Water Softeners Work?
Water softeners typically use a process called ion exchange. Here’s how an ion exchange system works:
- Water enters the water softener resin tank, which contains thousands of small plastic beads coated with sodium ions.
- As the hard water flows over the beads, calcium and magnesium ions are exchanged for sodium ions.
- The softened water then flows into your home’s plumbing system.
Eventually, the resin beads become saturated with calcium and magnesium and must be cleaned. This is called regeneration. During regeneration, a brine solution (saltwater) flushes the minerals off the beads and restores the sodium ions so the system can keep softening water.
Types of Water Softener Systems
Not all water softener systems work in the same way. Here are the most common types and how they differ:
Salt Based Water Softener
A salt based water softener uses ion exchange and is the most effective at softening hard water.
Pros:
- Removes calcium and magnesium completely
- Prevents lime scale buildup
- Improves soap and detergent performance
Cons:
- Requires salt refills
- Slight increase in sodium in drinking water
- Uses more water during regeneration
For large households, a dual tank salt based water softener is ideal because it ensures continuous soft water, even while one tank is regenerating.
Salt-Free Water Conditioners
Salt-free water conditioners don’t remove hardness minerals. Instead, they change the minerals’ structure so they don’t stick to surfaces. These salt free systems are often called salt free conditioners.
Pros:
- Low maintenance
- Doesn’t require salt or electricity
Cons:
- Doesn’t truly soften water
- Less effective for hard water
- Some scale buildup may still form in plumbing
Portable Water Softeners
Portable water softeners are great for RVs, campers, or small homes where space is limited.
Pros:
- Compact and lightweight
- Easy to set up and move
- Works well for travel or part-time use
Cons:
- Small capacity
- Frequent regeneration needed
- Not suitable for large homes
Key Factors to Consider When Choosing a System
Selecting the right water softener system depends on your household needs, water quality, and preferences.
1. Water Hardness Level
Water hardness is measured in grains per gallon (GPG). Anything over 3.5 GPG is considered hard water. You can test your water hardness using a DIY test kit or by contacting a water treatment professional.
2. Household Water Usage
To determine your water softener’s capacity, first determine your daily water use. Most people use about 75 gallons of water per day. Multiply that by the number of people in your home to estimate your daily water needs and determine what size water softener you need. Match that number with a system that has the right grain capacity.
Example: A family of four using water with a hardness of 10 GPG will need a system with a grain capacity of 3,000 grains per day.
3. Resin Tank Size and Quality
Larger tanks can go longer between regeneration cycles, which saves water and salt. Look for high-quality resin that lasts longer and supports more efficient ion exchange.
4. Water Flow Rate and System Controls
Check the water softener flow rate, especially if you have a large household. A good flow rate ensures you don’t lose water pressure when multiple fixtures run at the same time.
Modern home water softening systems include digital controls that track water usage and schedule regeneration based on real needs, not just time.
5. Type of Water Supply
If you have well water rather than tap water, you may need a more complex water treatment system. Iron, sulfur, and sediment can interfere with softeners and may require water filters.
Installation and Maintenance
Installing a Water Softener
A standard whole house water softener connects to your main water line, typically near where it enters your home. The process usually takes 3 to 5 hours.
When setting up a new water softening system you’ll need:
- Access to a power outlet
- A connection to your main plumbing
- A nearby drain for brine discharge
Most homeowners choose professional installation for a new water softening system, but some systems are DIY-friendly if you’re comfortable with plumbing tasks. We have a friend who is very handy and bought and plumbed his own water softener system. Unfortunately, even though he is a very handy person, he plumbed the system backwards, and it had to be fixed. For this reason, “DIY-friendly” is somewhat misleading when it comes to water softeners.
Maintaining Your System
Salt based systems need:
- Salt refills every 6-12 months on professionally installed systems
- Regular checks for salt bridges (older softener systems only, not in the new systems that are installed)
- Suggested annual cleaning/sanitation of the brine tank to prevent bacteria growth
- Yearly inspections of the tank and control valve
Maintaining your softening system keeps it running efficiently, reduces water waste, and extends its lifespan.
Benefits of a Water Softener System
- Cleaner Plumbing: Reduces hard water scale in pipes, faucets and shower doors
- Better Cleaning: Soap lathers more and rinses away cleanly
- Softer Skin and Hair: No more dryness from hard water
- Energy Savings: Improves appliance efficiency
- Extended Appliance Life: Protects washers, dishwashers, and other water using appliances
- Improved Drinking Water: Can reduce mineral taste
One of our neighbors had replaced the heater rod in their water heater three times before getting a water softener system professionally installed. We’ve maintained their system for them since the replacement and know that they have not had to replace the heater rod in their water heater since 2018. This example illustrates how a water softener protects and extends the life of both small and large home appliances.
Here’s a comment from one of our customers following the installation of a new water softener:
“HQ did an amazing job with our water softener system install. We noticed a HUGE difference in our water immediately (Lancaster city). Thanks again.”
“This is my first house with a water softener system. Steven was super helpful in answering all my questions, and did a really thorough job with the service. I can honestly say I feel a huge difference in the water “softness” as compared to other homes I’ve lived in, and am very impressed with the system HQ has installed in my home. No pushy sales pitch, and really nice to do business with.”

For Families
Dual-tank whole house systems ensure your family always has soft water, even during peak times like laundry day or multiple showers. This means no more prioritizing showers or waiting for the dishwasher to finish before starting a load of laundry; you’ll have a continuous supply of water for all your household needs, protecting your appliances and making everyday tasks easier. A dual tank whole house water softener is great for large families or families that have high usage during peak hours. Dual-tank water softeners are ideal for an uninterrupted soft water supply, especially for:
- Large Households & High Usage: Ensures continuous supply during peak demand, like multiple showers or laundry days.
- Commercial Applications: Essential for businesses (hotels, laundromats) that require a constant soft water supply for operations.
- Very Hard Water: Handles frequent regeneration cycles without downtime, always providing soft water.
- Optimal Efficiency: Often regenerates on-demand, saving salt and water, and extending system lifespan.
For Renters
Smaller water softener units or units available for rent can help reduce buildup in small spaces without major plumbing changes. These compact water softeners are perfect for apartment dwellers or renters who want the benefits of soft water without the commitment of a permanent installation, offering an easy way to protect your fixtures and enjoy softer skin and hair. Softeners can often be removed and installed in a new location if someone were to move and desired to take their system with them.”
For RV Owners
Portable water softeners make travel more comfortable and help protect your RV’s plumbing. By preventing hard water buildup in your pipes and appliances, these compact units extend the life of your RV’s systems and ensure a more enjoyable experience on the road, free from spotting on dishes and dry skin.
For Well Owners
If your home gets water from a private well, a combination system might be essential to ensure your water is both safe and soft. These comprehensive systems often include an iron filter to tackle metallic tastes and staining, a sediment pre-filter to remove particles like sand and rust, and UV purification to eliminate harmful bacteria and viruses. Together, these components work to deliver clean, soft water throughout your home. Work with your water treatment professional to determine which system or combination of systems is best for your unique water quality and desired outcomes.

FAQ: Everything You Need to Know
Is it safe to drink softened water?
Yes. It’s a common misconception that treated water contains high levels of sodium, making it unsafe to drink. The truth is, the amount of sodium added during the water softening process is minimal. For every 8-ounce glass, you’re typically looking at an increase of only about 20-30 milligrams of sodium. To put that in perspective, a single slice of white bread often contains more sodium than several glasses of softened water. It’s also worth remembering that sodium is naturally present in untreated water as well.
If you’re still concerned about sodium intake due to dietary restrictions, you have options. Many water softeners can utilize potassium chloride instead of sodium chloride (salt) for regeneration. Alternatively, for the purest drinking water, consider installing water filtration systems or a dedicated drinking water purification system like a reverse osmosis (RO) system at your tap. RO systems are highly effective at removing not only sodium but virtually all other water contaminants, providing exceptionally clean and great-tasting water for drinking and cooking.
How often do I add salt?
Most water softener systems need a salt refill every 6-12months. It is recommended to check the salt level in the brine tank each month and add additional salt as needed.
How long does a water softener last?
With proper maintenance, a water softener can last 15 to 30+ years, depending on the system and the quality of its manufacturing. We only recommend and install systems that have high quality manufacturing and an expected system lifespan of 20 to 30+ years. The heart of any water softener is its resin, and its lifespan significantly impacts your system’s long-term performance and value. While standard water softener resin may need replacement every 10 to 15 years, HQ Water Solutions utilizes premium, higher-quality water softener resin designed to last an impressive 20 to 30 years. This superior durability means fewer replacements and more consistent soft water for decades.
It’s crucial to understand that chlorine, commonly found in municipal water supplies, is highly damaging to water softener resin. Over time, chlorine can break down the resin beads, drastically shortening their effectiveness and lifespan, potentially necessitating replacement much sooner than expected. In such cases, or for optimal protection of your investment, HQ Water Solutions often recommends installing water filtration systems such as a chlorine removal system as a pre-treatment. This vital step safeguards your resin, ensuring it performs efficiently for its maximum expected lifespan, providing you with soft water and peace of mind for years to come.
Control valves should be serviced yearly or every other year to maintain quality.
Will a softener affect water pressure?
A water softener will not affect water pressure if it’s sized correctly. It may even improve flow over time by preventing mineral buildup in pipes.
Can I use a water softener with a tankless water heater?
Yes, in fact it’s recommended for tankless systems. Soft water helps prevent scale buildup, which can damage tankless heaters. In many cases, if hard water levels exceed the manufacturer’s recommendations, your warranty is often void as systems are expected to fail. So, a water softener may be required for homes with these tankless heaters to make sure the warranty is not voided.
Are salt free softeners effective?
When it comes to “salt-free water softeners,” it’s important to understand that they are actually salt free water conditioners. Although they reduce hard water scale buildup in pipes and on water using appliances by altering mineral structure, salt free water conditioners don’t remove hardness minerals like calcium and magnesium. This means you’ll likely still experience the typical hard water side effects such as dry hair and skin, the taste of minerals in your water, and persistent water spots on dishes and fixtures. For true mineral removal and complete relief from hard water issues, a salt free water conditioner isn’t as effective, and a salt-based softener remains the most comprehensive solution.
Do water softeners waste water?
Modern metered systems only regenerate when needed, keeping salt and water use low. The benefits of appliance protection often outweigh the small water cost.
Final Thoughts
The best water softener system for your home depends on your water hardness, daily usage, and personal preferences. Whether you want a powerful dual tank setup for your family or a smaller water softener for your apartment, there’s a solution that fits.
