Concerned about that funny chlorine smell in your drinking water?    

While chlorine may conjure visions of swimming pools, did you know that it has been widely used as a disinfectant for drinking water since the early 1900s? In fact, chlorine has not only revolutionized water purification it has been hailed as the major public health achievement of the 20th century! 1

Today, chlorine remains the most widely used chemical for water disinfection to ward off waterborne diseases (for example, typhoid, hepatitis and cholera).2  But recent hoopla about water disinfection byproducts (DBPs) – which can make their way into the water supply – can lead to concerns about tap water safety.  To help consumers sort the facts from the myths, let the Culligan Man answer  some top consumer questions:

1. What is a disinfection byproduct?  

DBPs form when disinfectants used to treat drinking water react with naturally occurring materials in the water. Trihalomethanes and haloacetic acids are the primary byproducts that result from the use of chlorine as a disinfectant.1,2

2. Are there actions being taken by federal and local agencies to monitor or reduce DBPs?  

The EPA has regulated the presence of DBPs since 1979 to address potential health risks posed by chlorinated water. 1 And, in some communities, the EPA has even required water utilities to reduce the amount of DBPs by switching to alternative disinfectants such as chloramine. 3

3. How do I know if my drinking water contains DBPs?  

If you have concerns, you can turn to a couple of easy to access, reliable resources.  Obtain a free copy of your Consumer Confidence Report from the EPA to see exactly what is in your local municipal water supply and how it is being treated before it reaches your home or simply review your annual water quality report that you receive from your local water utility.

4. What can I do to limit DBPs in my home’s drinking water?

Consider adding a household drinking water filtration system for an extra level of security.   Culligan’s patented water filtration technology – including systems like Aqua-Cleer® – can be customized to reduce impurities4 in your water like aesthetic chlorine, lead, radium, and cysts.

Can a Water Softener Really Make Your Other High Efficiency Appliances More Efficient?  

The major appliances in your home – refrigerators, washing machines and dishwashers – consume a hefty portion of your monthly utility bill.  That’s why many savvy homeowners have switched to high efficiency appliances that use half the energy of older models and can cut costs by up to $2,000 per household1

Recent Study Exposes Hard Water Drains  

But consumers who’ve invested in high efficiency, water-using appliances may unknowingly be cancelling out their benefits if they don’t have soft water.  Imagine purchasing a brand new, high efficiency washing machine only to have to de-lime it due to scale and deposit build-up after only 30 days!  That’s what a recent Water Quality Association study found, along with the effects of untreated hard water on other home appliance like water heaters.2  According to the report, using hard water also caused…

  • Premature failure of tankless water heaters due to scale plugging in the downstream plumbing after only 1.6 years of use;
  •  24% loss of efficiency in gas storage tank water heaters;
  •  Shortened lifespan of the heating element in electric water heaters due to scale buildup that raised the operating temperature.

 Soft Water Boosts Equipment Performance

In contrast, the same study found that soft water can actually improve the performance and lifespan of these appliances2.  That’s good news for homeowners who don’t want to see their investment in high efficiency units go right down the drain.  In fact, soft water can actually make these appliances even more efficient.  The report showed that by using soft water:

  • Gas storage tank and tankless household water heaters maintained their original factory efficiency rating over a 15-year lifetime;
  • Tankless water heaters running on soft water can help recover the cost of a water softener and operating supplies in just one year;
  • Reducing washing machine water hardness is 100X more effective at stain removal than increasing temperature or detergent dose.  Detergent can be cut by 50% and temperatures run as low as low as 60ºF with the same stain-banishing benefits!

Smart Softening Leads to Savings  

If you’ve made the investment in high efficiency appliances there’s one way to make sure the energy and money savings start flowing: installing a high efficiency water softener, like the Culligan HE Water Softener.

The Culligan system cuts energy usage by up to 46% and operating costs by 60%3 - while also ensuring you’re getting the most from your other high efficiency appliances.
