Step 1: Determining what Water Treatment System is Right for You:


There are several factors homeowners and businesses face when considering their water treatment needs. Systems typically fall in one of two categories:


​POE (Point of Entry) System – Treats entire home, business, etc.

POU (Point of Use) System – Treats localized problem, drinking water, etc.


Problem Area 1 =      Hard Water – Causes scale build up, appliance failure and much more.

                                    Treated with a Water Softener / Water Conditioner / Multi-Media System


Problem Area 2 =     Contaminants, Chlorine, Chloramines, Bad Taste, Bad Odor, VOC’s & much More

                                    Treated with Whole Home Water Filtration / Multi-Media System.


Problem Area 3 =     Safe Drinking Water – Point of Use

                                    Treated with Filter Systems or Purified Drinking Systems (Reverse Osmosis Systems)


Important Note:


If the water loop was put in during the construction of the home, there is a 99% chance the cold side of the kitchen sink is bypassed. Therefore, none of the water will be treated at all with any (POE) whole home system, and you may still want to consider an under-sink (POU) filtration system or reverse osmosis for cooking and drinking water.


Depending on the age, and style of the home it is possible to have a simple re-connect done on the plumbing this runs $250.00 - $275.00. In some cases, to complete this it can be very expensive requiring drywall to be cut open etc.


If the water loop is put in after construction all water supplies are treated. If you are installing any system that uses salt or potassium to soften the water, you may want to consider adding a (POU) system under the sink (reverse osmosis system) to remove any leftover sodium residue from the water. In most cases this can also be connected to the refrigerator (ice line).


Step 2: Determine Plumbing Requirements:


Do you have a loop? This is necessary for any point of entry system (Softener / Conditioner / Whole Home Filtration / Whole Home Reverse Osmosis) If not, it is recommended to schedule a Free On-Site to determine options and costs:


How do I know if I have a loop?


Normally you will see a section of 3/4" - 1" copper plumbing shaped like the

diagram located in the garage.


Establishing a loop can range from $275.00 to $900.00 or more, on average

the loop charges run $450.00.


Drinking Water Filters/ Reverse Osmosis / Water Coolers / Ice Machines


Does the counter-top need hole drilled for faucet? Ice Line Pre-Plumbed? Electrical and or Drain for Pumps, UV, Ice Machines, Coolers? Free On-Site offered determine options and costs


Step 3: Determine Size Requirements for point of Entry Systems:


How do I know what size system I need?


(Based on a Regeneration cycle of every 7 days for most efficient operating parameters)


Take the total number of people in home multiplied by an average gallons per day per person of 75 (national avg.) multiplied by water hardness (20 is avg. for Phoenix and surrounding cities) = daily grain requirements, multiplied by days of recommended regeneration (7) equals unit size.







You should also take into consideration the # of bathrooms and if you have multiple body sprayers and frequency of quests. You should always consider rounding up to the next size unit to cover extra factors plus your system will operate more efficiently using less salt and regenerating less. The difference in costs upfront is minimal and will pay for itself many times over.


Another Quick Rule for the most common sized units is as follows:


​32K - 32,000 Grain - 1.0 Cu. Ft. -   9 x 48 - 1 to 3 people

48K - 48,000 Grain - 1.5 Cu. Ft. - 10 x 54 - 3 to 5 people

64K - 64,000 Grain - 2.0 Cu. Ft. - 12 x 52 - 5 to 8 people


​ If you are considering a mixed multi use system than always increase one size.

Specific Contaminants – Fluoride, Arsenic, Lead, Chromium etc.


Some contaminants are expensive to treat, require specific filters and system types.


Important Notice:

Some companies promote whole home filtration proving safe drinking water to the entire home eliminating the need for additional water treatment products like a reverse osmosis. This in most cases is not true. First there is a good chance the cold side of the kitchen sink is bypassed and the water is not treated, this is where 99% of cooking and drinking water is taken from. Secondly if the cold side is not bypassed you have to consider the taste, if you prefer purified water you more than likely will not be happy.

Whole Home Filtration Notes:

The most common reason homeowners choose a whole home water filtration system, is to remove Chlorine, Bad Taste and Odor. There are a number of specific contaminants that some people also look to remove, therefore the system should be customized to meet your individual needs.


Organics (including VOCs, or "Volatile Organics"). In this category the EPA lists 32 very nasty chemical contaminants — many with familiar names like benzene, dichlorethylene, carbon tetrachloride, dioxin, styrene, toluene, chloroform, and vinyl chloride. To give an idea of the extensiveness of this list, a single one of the 32 items is "Total Trihalomethanes", a category made up of still uncounted chemicals, assumed to number in the thousands that are formed when water containing organic matter (i. e., virtually all water) is treated with chlorine.


Organics category, the primary treatment in all cases and the only recommended treatment in most cases, is activated carbon.


Pesticides category lists 14 familiar poisons such as Aldicarb, Chlordane, Heptachlor, and Lindane. In all 14 cases, activated carbon is the only recommended treatment. Of the 12 Herbicides listed (2,4-D, Atrazine, etc.), activated carbon is the only treatment recommended.


Chlorine removal is what carbon is best at, and nothing else equals carbon's ability to remove chlorine.


What carbon filtration doesn't do can be seen in the remaining three categories of the EPA contaminant list. Carbon is mentioned as a treatment for only one of the four Microbiological contaminants listed: turbidity. It is not recommended for coliform removal or for cysts, though ironically, some of the very tight solid carbon block filters now on the market remove bacteria (though manufacturers seldom make this claim) and cysts like giardia and cryptosporidium quite handily.


The same is true in the Inorganic category. Activated carbon itself appears in the EPA list as a preferred treatment only for mercury, but carbon block filters can also be engineered to remove lead. Some are NSF-certified for lead removal and for asbestos removal. By large, removal of inorganics is the property of reverse osmosis, distillers, and ion exchange systems.


The same is true in the final category, Radionuclides, where carbon is ineffective and reverse osmosis (RO) and ion exchange are definitely the treatments of choice. Radioactive forms of elements are called radionuclides. Some occur naturally in the environment, while others are man-made, either deliberately or as byproducts of nuclear reactions.
