Maybe you're just thinking about making an appointment with a
Culligan Man, or maybe you've already scheduled a time for your
local Culligan Man to visit your home - you might be wondering
what you need to know or do to be prepared. Expect your Culligan
Man to have a lot of questions for you, like:
- What are the biggest problems you have with your
- Have you noticed any strange smells or tastes
- Does your water look and feel the way you think it
- Do you have limescale buildup or rust stains
You'll also want to think about the kinds of things you're
curious about ahead of time, just to be sure you don't forget
anything when it comes right down to it. Consider talking over
these important topics:
- What's best for my home - whole-house filtration or a
- Will the unit produce enough treated water to meet daily
- What are the expected maintenance costs for specific
- Is there a maintenance schedule & will I need to
- Any disposal or waste materials (salt, etc.) & who
- Expected impact to utility costs?
- Will I know if something goes wrong?
- How different can I expect my water to look/taste/feel
with a softener?
- What are my water softener rental options?
It's also always a good idea to be prepared to talk about your
budget since it will help you and your Culligan Man feel better
about getting the right water treatment solution for your needs.
Think about this ahead of time, and have the conversation with
spouses/significant others so you know your household is on the
same page, you know what you're looking to spend, and how that
aligns with everyone's expectations.

Life is hard enough without having to worry about whether your
water is. Here are some simple answers to those hard water
What is Hard Water,
Hard water, simply put, is water with higher-than-average
mineral content. What "average" is may depend heavily on your area
out what the water is like near you) but generally refers to
water with between 120-180 ppm of dissolved minerals like iron,
calcium, manganese, or others. Typical freshwater can range between
15 and 385 ppm, though anything over 180 ppm is considered very
What Causes Hard
Geography has a lot to do with it - since water accrues its
hardness passing through mineral deposits and sediment present in
soil, the properties of your local water generally depend on the
properties of the landscape around you. Mountains outside town
known for their high iron or limestone content? There's a good
chance you'll have dissolved minerals tagging along to your
Infrastructure can also impact the mineral content and overall
hardness of water by the time it reaches your faucets. For example,
aging pipes and municipal water systems can leach iron or magnesium
into water as it travels through the system.
How Can I Tell if I Have Hard
There are a few easy ways to tell if your water is hard, and
while you'll probably need an
expert water test to determine the extent, signs that
things may be harder than normal can be relatively simple to
- Limescale buildup on fixtures and drains
- Reddish color or stains left on sinks and tubs
- Scratchy laundry or dry skin
- Soap that doesn't lather easily or requires a large amount to
- Taste, odor, or feel that's "off"
What Can I Do to Fix
The solution depends on what bothers you most about your hard
water. If there's a taste or odor that's bothersome while other
hard water symptoms aren't as big a deal, an under-sink or
point-of-use filterprovides treatment where you're most
commonly drinking and using water. If it's the scratchy laundry or
the burned-out dishwasher or residue all over your coffee maker you
just can't stand, then a
whole-home water treatment solution will be able to target
the source of your problems.
The best way to know for sure is to have a
Culligan Man test your water, so once you know how hard it is -
and what exactly is making it that way - you can discuss the best
option(s) for addressing it.
What's in a
As it turns out, quite a lot. Salt-free water softeners have
been walking a line between vaguely misleading and downright
confusing since their emergence into the water treatment market.
Where the confusion starts is the "softener" portion of their name.
By definition, softeners remove hardness from water, which
typically includes minerals like calcium and iron that give water
its hard qualities. So, if we follow this definition and
understanding of what a water softener is, a salt-free softener is
a bit of a contradiction.
What Do Salt-free Softeners
salt-free softeners rely on the process of ion exchange to
reduce sediment, odor, and chemicals from water, so the taste and
smell of treated water ends up being much more agreeable, but won't
actually provide the benefits most people are looking for from a
water treatment system, like removing scale buildup or increasing
the efficiency of washing machines and dishwashers.
In salt-free processes, the actual minerals remain in the water;
their chemical form is simply manipulated so that it is less likely
to adhere to surfaces. Technically, this process falls under the
category of water treatment referred to as "water conditioning."
This solution may also provide some results in terms of scale
reduction and softer laundry, but not to the extent most people
think of when they think about water softening.
Benefits of Salt-free
While salt-based systems will generally outperform their
salt-less counterparts when it comes down to salt conditioning,
there are some advantages to a salt-less system:
- Relatively maintenance-free
- Some reduction in scale buildup
The best way to know which type of system will be right for you
and your home is to
talk with your Culligan Man after he or she tests your
water. Once you know what kinds of minerals you'll need to address,
you can discuss the most optimal options for your water.
It's that time of year again! Starting May 1 we'll be
celebrating Drinking Water Month by kicking off our first ever
Hydration Celebration promotion.
Spring is the perfect time of year to make, or remake, some
healthful resolutions, and what you drink can be one of the
simplest changes you can make. We know the health and personal benefits of drinking more water are many, and as it turns
out, there are even more advantages that come in the form of
creating more economically and environmentally friendly drinking
water choices. Rather than spending more on single-use plastic
water bottles, an under-sink system or Culligan water cooler is an
easy way to get bottled-water taste, sans the price and the
recycling hassle that comes with them.

Like most filtration systems, reverse osmosis works by funneling
contaminated water through a semi-permeable membrane that removes a
specific set of impurities. Unlike some other solutions, the system
applies pressure to the water as it flows through the membrane,
using the natural tendency toward chemical equilibrium to trap
offending ions (like salt) in order to achieve the desired state of
contaminant-free water. The membrane traps impurities, usually
around .001 microns or larger, so that what exits the membrane to
your faucet is purer, potable water.
Reverse osmosis technology was developed during the 1970s, and
is most commonly used to desalinate water in areas where fresh
drinking water may be hard to access. RO is also common in
industrial applications, like our very own Culligan Matrix Solutions Reverse Osmosis, where it can be used
to treat water for facilities and recycle commercial
How does reverse osmosis work to treat my
Residential systems use the same pressure membrane technology to
separate contaminants from municipal water, and may include
additional filtration steps like sediment filtration or UV
sterilization. Our residential reverse osmosis systems, for example, include
pretreatment as a matter of course, and post treatment as needed.
If water quality is especially concerning in your area, you'll want
to make sure your RO system is used in conjunction with a
sterilizing filter to ensure water is not only free from saline and
other particles, but any harmful contaminants like E. coli or
arsenic. These features are always included in Culligan reverse
osmosis products to ensure the highest-quality result for your
What types of water problems does it work best
RO works best for water with high saline content and relatively
few other impurities. Beyond salt-water fixes, reverse osmosis can
also be used to remove chlorine and fluoride from drinking water,
and in general, be used to remove a variety of:
It can be challenging to know exactly what type of filtration
product is right for your home and your water supply. Whether
you're considering reverse osmosis, or any other type of
filtration, it's helpful to have your local Culligan Man test your water in order to make the best recommendation
based on the unique needs of your tap.
Ever wondered if there was a way to filter water, no nasty
chemicals or salt hassle required? Culligan has been on the front
lines of breakthrough technology like UV filtration for
generations, and we're hard at work expanding on the technology
that allows us to provide effective filtration for every kind of
How UV Systems Work
UV disinfection has been used for decades in various capacities
after the germicidal properties of sunlight were discovered. It
wasn't long before this naturally occurring phenomenon was
harnessed to focus specific spectrums of ultra violet light toward
eliminating harmful microorganisms like bacteria, viruses, and
certain pathogens from water.
In general, UV light is applied through a combination of gas
applied with a voltage that creates the desired disinfecting
wavelength. This is all contained in, typically, a quartz sleeve
that water passes through during the disinfection process. Ultra
violet light can, when properly applied, eliminate most of the
leading causes of waterborne illness like:
Benefits of UV Treatment
Using ultra violet treatment can come with a variety of
- Low maintenance,
- Reduced carbon footprint
- No treatment by products like salt
- No chemicals (chlorine etc.)
- No change to taste, smell, or appearance of water
Will it Work for My Water?
Well water generally has the highest risk for carrying or
containing protozoa like giardia because of the availability for
ground water contamination and/or runoff, so while it may be useful
for those using municipal water, there's generally more need for
those served by wells.
What's also important to understand about UV water treatment is that it is only effective in water
that is already mostly pure. For example, dissolved sediment and
minerals like iron, manganese, and sulfur can impact how
effectively ultra violet exposure renders microorganisms inert. If
water is hard to begin with, pathogens can essentially hide behind
iron or sulfur particles, making the treatment ineffective. In many
cases, ultra violet applications are used as the last in a series
This in mind, if your water is already soft but you're concerned
about contaminants, UV treatment may be a perfect solution. In
order to know for certain, it's easy to have a Culligan Man test your water and evaluate flow rate to see if a UV
filter makes sense, or if it should be used in conjunction with
another type of filtration like a softener.
We probably all have a general sense of what water should look,
smell, taste, and feel like, but sometimes it's not always obvious
when there's something wrong with your water.
Self-Diagnosing Problem Water
While some contaminants are better at hiding than others, there
are a few telltale signs that something is causing a problem with
- Odor: If something smells suspicious, it
probably is. Common pause-giving smells you might come across in
tap water include:
- The Pool Smell: Easily identifiable from our
associations with swimming pools, high chlorine levels in water are
usually to blame for this olfactory affront.
- Something's Fishy: This
you-know-it-when-you-smell-it water scent (also often
associated with rotten eggs) is perhaps the most unpleasant one,
and is typically the nose-wrinkling result of dissolved sulfur not
so subtly stowing away in your water supply.
- A Little Too Natural: We all want our water to
be fresh from the source, but sometimes there can be too much of a
good thing. If water smells earthy, grassy, musty, or moldy,
there's a good chance bacteria could be to blame.
- Anything but Nothing: A good rule of thumb is
that if water smells like anything - organic, chemical, or
otherwise - it's time to call in a Culligan Man to test it and ensure it's safe to
- Taste: Not unlike the smell situation, you
want water to taste like water. If it doesn't, it's likely you've
got a problem - how big or small can sometimes be determined by
what exactly you taste.
- The Metal Head: If you've ever come across the
singular tinge of iron in water, it's likely you'll remember it.
Other causes for metallic tastes can include dissolved mercury,
lead, copper, manganese, zinc, or arsenic.
- Essence of Ocean: There's a reason we react
negatively to consuming salt water, so if your water has that
beachy tang, it's a possibility there may be certain kinds of
bacteria and/or sulfates affecting the supply.
- Appearance: We also have certain expectations
of our water's visual quality. You should be able to see through
it, for instance.
- Cloudy with a Chance of Contamination: This
particular visual distraction also masquerades under the guise of
turbidity. Essentially, any time your water is cloudier than you
expect, and/or lingers after water is allowed to settle, that's a
sign of problem water.
- Off-Color: This may be a bit harder to tell,
but if water has any sort of hue to it, you'll want to get a water
test. You might also notice colors left behind by water in the form
of rust-colored stains around drains and fixtures.
The way water looks, tastes, and smells is often a product of
location and geography. To read more about the qualities of water
