What is "City Water"?

"City Water" is what we call water that comes from a public water supply source. Whether it originates from wells, rivers, streams, springs, cisterns or aquifers, a municipal water supply is still considered public in the way we treat the water because it is chlorinated. If it has chorine in it, we consider it a public water supply. Virtually all public city, town or municipal water supply systems are chlorinated or use chlorimine. If you get your water from a private well you can click HERE for instructions, solutions and prices to correct any water problems you may have. Private well water is not usually chlorinated unless the homeowner has added chlorine to it themselves. If you pay a water bill then you most likely have "City Water". If you still aren't sure what kind of water you have give one of our expert technicians a call to help you determine your water type.

How Do I know Which Method of Water Filtration to Use"

On this page we will talk about the different choices a person normally has to consider on "City" (Municipal) water treatment systems. They range from sediment and carbon cartridge filters, to water softeners, water conditioners, full sized carbon tanks and "Multi Purpose Water Treatment Systems" that have water softening and carbon water filtration all in one tank (Dual Purpose Conditioner). We also cover drinking water systems that are called "Reverse Osmosis Drinking Water Systems." They are used by people who have water softeners and want to remove salt, sodium and potassium from their drinking water that water softeners can leave behind.

Replaceable Water Filters for the Home or Business

There are two common kinds of replaceable cartridge type water filters. The canister that holds them will look the same, but the filter that goes inside the canister will be different.

In Line Sediment Filtration

Sediment FilterOne is a sediment water filter. Sediment filters can be used for the whole house to remove dirt, rust, sediment, sand etc. It goes on the main water line leading to the rest of the house. The cartridges can be replaced as needed. Normally at intervals of 3 months, 6 months or a year depending on how much foreign substance is in the water. Cartridge filters come in 4 basic sizes. They are 10" or 20" in length and either are a regular width (2 3/4") or 4.5" which is a High Flow Water Filter application. If you know you have 15 GPM or more, you must use the 4.5" filter. If it is a moderate filtering problem and you have a normal water flow rate in your home, then a 10" water filter is ok. Most people would probably use a 20" anyway, as it will last a great deal longer and has a much larger surface area. If you have a flow rate in excess of 15 gallons per minute, or higher water pressure, then a High Flow Filter Cartridge would be the best option. It has a massive surface area, especially on the 20" version. It is ok to have a filter that is too big, but not one that is too small.

In Line Carbon Filtration

The second type of common replaceable cartridge water filter for the entire home is called a Carbon Water Filter. Carbon filters are normally used to remove chemicals such as chlorine and chloramines. Carbon can remove other common contaminants such as arsenic and pesticides. Keep in mind however, if you have a water softener then the carbon filter should go BEFORE the water softener. Carbon filters DO NOT remove the salt, sodium or potassium that water softeners leave behind.

Brita Type Filters are made of carbon. Very small amounts of carbon. Brita filters DO NOT remove the sodium that water softeners leave behind. If you have a lot of chlorine, Brita filters are certainly a marginal approach. While they mask the smell and taste of chlorine, most of it is still coming through the filter after just a few days. Refrigerator filters are generally carbon based filters. Refrigerator filters DO NOT remove the large amounts of sodium left behind by water softener systems. Most fridge filters are better than Brita type filters but our carbon filters are far superior to fridge and Brita filters.

If you determine you want to use a replaceable carbon cartridge for the whole house, you should consider putting a sediment type filter in front of it. Carbon filters are more expensive, so the sediment filter will make the carbon filter last much longer. Carbon cartridge filters can reduce chlorine in the water. If there is little or no sediment in the water, then using a carbon cartridge filter only is fine. If you have a great deal of chlorine in the water and want it all removed from the entire home, you should consider a full house backwashing carbon tank.

Twin Replaceable Cartridge Water Filters

Normally the best solution before any water softeners or other devices is a combination Sediment/Carbon whole house filter. The first filter features a high quality sediment cartridge to remove dirt, sediment, sedimental iron from old city water pipes, sand and other unwanted debris and particulates. That filter would be followed by a very high capacity carbon filter which removes or reduces chlorine, chemicals, arsenic, could odors, bad tastes etc. Together they make the best whole house water filter cartridge system as well as great pre-filter for water softeners, water conditioners and complete whole house water treatment systems. They offer great protection for dishwashers, hot water heaters, toilets, faucets and fixtures etc.

Chlorine levels and treatment chart:

Determining if you need carbon type filters for the whole house is simple. The best way to determine if you need to use carbon is to test the water at the house for chlorine levels. You can buy an inexpensive tester from us for around $10, or pick one up at the local swimming pool supply store. They are very easy to use. Or you can take a fresh sample up to the pool supply store and they can check it. You need to have the sample there within a few minutes from the time you draw the sample. The pool supply store will generally test a sample for free. Once you have determined how much chlorine you have in the water, you can use the following chart to determine what type of filter you may need. NOTE: If you are using a backwashing carbon tank anyway, you really don't need to worry about how much chlorine is in the water. Our backwashing carbon tanks can handle most municipal water supplies chlorine levels. It is always best to know how much chlorine is present in your water to ensure that we use the correct application of filtration.

Please Note: If there are large amounts of dirt, sediment, sand or oxidized iron in the water then a sediment style cartridge filter should be used in front of the carbon filter. Sediment cartridges are less expensive and will make carbon filters last much longer normally.

Chlorine Level (ppm/mgl) Solution
0 to 0.5 None Needed or Cartridge Filter
0.5 to 1.5 Cartridge Filter, Carbon Tank, Dual Purpose
1.5 or more Carbon Tank, Dual Purpose

When drawing a chlorine sample for water testing: First turn your cold water on for five minutes. Open the faucet as much as you can. It is important to run as much water as possible during this time, so the more water you run the better. We don't want to test water that has been sitting in your home's pipe. We want to test the water coming from the street or municipal pipes. If you are taking the sample to a pool supply store, try to draw the sample immediately before leaving. You want to draw the sample and deliver it to the pool store as quickly as possible as Chlorine begins to dissipate over time. The water needs to be unfiltered, so bypass any current water softeners or filters you may have. You may use a plastic bottle with a plastic lid to collect your sample, just make sure to rinse it with water and DO NOT use any soap. Fill it to the top so there is no air in the sample. A soda bottle or drinking water bottle is fine for the sample. It does NOT need to be a sterile container as we are not testing for harmful bacteria in this situation.

Full House Backwashing Carbon Tank Water Filtration

Carbon TankIf you have a great deal of chlorine in the water and want it all removed from the entire home, you should consider a full house backwashing carbon tank. They are a bit more expensive initially, but are very economical over time, and require far less maintenance than cartridge filters. Generally the carbon gets replaced every 3 to 5 years at a nominal cost. Far less expensive then using replaceable cartridge carbon water filters, normally. Backwashing carbon tanks remove or reduce many unwanted contaminants from the water including, dirt, sediment, chlorine, chloramines, arsenic, organics, inorganic, mercury, benzine and much more.

Carbon does not remove sodium, nitrates, fluoride, hardness etc. They clean themselves so they are virtually maintenance free. Just set it and forget it. Many people use a whole house carbon tank in conjunction with reverse osmosis in the kitchen for cooking and drinking water. Reverse osmosis can remove sodium, nitrates, fluoride and other dissolved solids for drinking water. If you have a water softener as well, then you need to have reverse osmosis in the kitchen to remove salt, sodium and potassium that all water softeners leave behind, or simply drink bottled water. If you have no water softener in the home, a reverse osmosis unit becomes more of a luxury than a necessity as the backwashing carbon tanks makes the water very clean, and it tastes and smells really good.

Dual Purpose Water Conditioner

The Ultimate Home Water Treatment System

Our most popular city water solution. We stack a full sized carbon tank on top of full sized water softener. This allows the carbon tank to be cleaned at the same time as the water softener, using the same water. This is an economical solution if you pay for your water. They both clean at the same time instead of having two separate units that have to clean them selves. This unit is also very stingy on salt usage. The average customer can expect to only add salt about once per year when properly applied, and carbon replacement is only needed every 3 to 5 years and is very inexpensive and easy to do. This single unit can replace entire treatment systems from in-home sales companies costing thousands of dollars. Add reverse osmosis in the kitchen and you have the most complete water treatment system on the market.

What's inside: Two HUGE 10" x 30" tanks, each with 1 cubic foot of media inside. One with softener media the other with activated carbon (or another media if you wish) to remove chlorine, chemicals, sediment, tastes, odors, arsenic and many other unwanted contaminants. Makes those other soft water companies' equipment look like "Tinker Toys." Replaces Culligan®, RainSoft®, EcoWater®, Hague®, Kinetico® and all other home soft water treatment systems for a fraction of the cost! These units are completely customizable.

Reverse Osmosis Drinking Water Systems From $199

Reverse Osmosis SystemIf you want the cleanest drinking water possible, these reverse osmosis (RO) drinking water systems are the ultimate choice. If you want to drink water after a water softener then an RO system provides convenient access to clean water and is far more affordable than drinking bottled water. You should never drink water directly from any water softener, as by design they replace hardness with sodium. Our RO units remove the unhealthy sodium and salt softeners leave behind as well as other dissolved solids, nitrates and heavy metals. Compare to in-home sales company's units costing $1000 to $2000. The filter replacements are once per year at a cost of $39 for all the replacement filters you need. When properly applied, there is an inexpensive membrane that needs to be replaced every 5 years. This membrane takes you from an average filtration of 1 to 5 microns normally found on marginal drinking water filters, to less than 2/1000th of a single micron.

Our state of the art ROs remove a very wide range of contaminants including Sodium, Salt, Nitrates, Fluoride, Lead, Heavy metals, Cysts, Cryptosporidium, Bacteria, Tastes, Odors, THMs, Chlorine, Radium, Dissolved Solids, Pharmaceuticals, Sewage Treatment Plant Waste and much more. The very BEST in purified great tasting drinking water!
