  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 Culligan dealer in San Diego 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!

San Diego Hard Water

According to the City of San Diego, drinking water in San Diego averages about 16 grains per gallon (gr/gal) or 276 parts per million (ppm). The USGS classifies more than 180 ppm as “very hard” But what in it actually makes it hard? It’s generally the magnesium and calcium content.

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 can I removed salt from softened water?

The added sodium to drinking water through the water softening process may be a concern to those with a low-sodium diet or other health concerns. Reverse osmosis systems remove salt and other impurities for a single faucet, or the entire home.

Does Culligan offer California-approved water softener installation and maintenance?

Culligan understands and follows all state and local plumbing codes and regulations provided by the UPC (Uniform Plumbing Code) and CPC (California Plumbing Code) for water softener installation and maintenance. This includes understanding requirements for venting, drainage, and back flow prevention.

How do water softeners affect septic systems?

Water softeners require additional water for regenerative purposes, but are rarely known to cause issues in septic systems if an expert handles the installation. Culligan experts understand septic system capacity and its relationship with water softening systems better than other third-party installers and general plumbers. We also use septic-safe softener cleaners only.

Does hard water cause dry skin?

Hard water can cause dry skin if you have sensitivity to such issues. Calcium and magnesium are examples of mineral that can leave a film on your body and prevent your shower products such as soap and shampoo to get through the surface. Studies have also shown areas with hard water are more likely to have children with eczema.

What is the installation time for Culligan Water Softeners?

Since a site inspection and water test is required, Culligan Water Softener installation is a little different than buying a softener online and asking a plumber to install it. This work on the front end helps mitigate issues down the road. The installation process usually only takes a day or two depending on work needing done on drain lines, your water supply, and electrical connections. Your Culligan expert will always test the softener after installation to ensure it is working properly.

What softener is right for my home?

After site inspection and water analysis, your Culligan expert will help pick which softener is right for you based on your budget and home needs.
