Why Choose Culligan Water Softeners For Your San Marcos Home?

Our water softeners are second to none. But the real secret: We make water treatment easy.

  1. Expert Installation. Easy To Use.

    Culligan has been in the water treatment service business for more than 85 years…and it’s all we do. Your local Culligan delivers, installs and maintains your water softener system for you, so you don’t have to! No worries about shipping damage, unboxing, or installation location. Just schedule an appointment, then relax and enjoy the soft water!

  2. Choose Expertise Over Generalists

    There are dozens of softener brands. There are hundreds of types of pipe fittings. Your home is unique. Do you trust a third-party plumber to get it right? Your local Culligan knows its product, and is familiar with the homes in your area. Most importantly – we know how to install water softeners – it’s all we do!

  3. Make Your Water Work For You

    On the fence about whether you need a softener? You could enjoy these benefits – that pay themselves off in no time!

    • 24% in energy savings by using softened cool water to wash clothes [1]
    • 30% more out of your water-using appliances when water contaminants are filtered out [2]
    • 50% in reduced detergent costs when washing laundry, hair and body in soft water [3]
  4. Why Price Tags Are Deceptive

    Unless you were an expert installer, you wouldn’t buy a water heater directly off Amazon. However, big box retailers, both in-store and online, take this transactional approach to homeowners for water treatment. They offer you low price tags for incentive. But what they don’t tell you about are the installation hassle, the third-party customer service on both ends, and how you’re left to your own devices to maintain your system – don’t forget, your home is unique. There is no one-size-fits-all solution. If you truly want to save throughout the life of your system, go with the expert!

Having our water softened made ALL the difference. We went from extremely hard water to drinkable water, and there was immediately a positive difference when taking a shower and washing our clothes. The service techs are very knowledgeable and friendly. They get in, do the job, and get out. We are very happy with both the products and the service.

You Have Questions

We Have Answers

Will my water taste salty?

No. A properly functioning water softener will never make your water taste salty. The small amount of sodium added to the water will never create a salty taste.

How do I know if I have hard water?

Hard water usually manifests itself in several ways. It leaves white residue behind wherever water evaporates. When hardness reacts with soaps and detergents, it leaves a sticky soap scum behind, and in hot water heating systems it leaves behind a hard scale.

How does a water softener work?

A water softener works through a process known as “ion exchange,” which means that as it removes calcium and magnesium (elements that make water “hard”), it replaces those ions on a one for one basis, usually with sodium. This means that the amount of sodium added to the water is directly proportional to how hard your water is. In most instances the amount being added is so small that it is not a significant contributor to the amount of sodium in your diet.

Will a water softener reverse the damage that has already been done to my appliances?

Yes, if your hard water has been building up scale in your appliances, once you install a softener it will begin to remove that built-up scale. It will take a long time to remove it, but it will remove it.

Will the softener remove all impurities from my water?

Unfortunately, no. A water softener is designed to remove hardness (calcium and magnesium) from water. They can sometimes remove a limited amount of iron and manganese if you happen to have these problems as well. But if you are looking for great water for drinking and cooking, you should probably consider a reverse osmosis system for that purpose.

Are there chemicals used or put into the water to soften the water?

Other than salt or potassium chloride, there are no other chemicals that a water softener uses. On the contrary, using a water softener reduces the amount of cleaning supplies and detergents that you need to put down the drain trying to keep your home and family clean. Using a water softener is very environmentally friendly.

How long after installation will I have soft water?

Once a softener is installed, it will begin to soften your water immediately, However, if you have a tank-type hot water heater, it may take a few days to use up that hard water, until you feel the full effects of soft water.

How often do I need to add salt?

Most good softeners today, recharge based on how many gallons of water you use, and how hard your water is to start with. However, most of our customers today are adding salt once or twice a year, on average.
