Several year ago the EPA had recommended that states that the United States water supplies, city water supplies, municipal water supplies switch from using chlorine to sanitize to using chloramine. The difference is, is that the chloramine from what I understand that its a combination of ammonia a chlorine. There is ammonia naturally existing in the water so when you add the chlorine to it you can have the natural occurrence of this. The idea was because it’s able to sanitize better it would stay in the solution longer and actually make the water taste better because chlorine actually give the water an objectionable taste and small. Shortly after the EPA recommended the change (See what is in your drinking water) oops we think we opened a pandora’s box. When you chlorine sanitize there are disinfectant byproduct toxins like trihalomethanes and cancer causing substances that now are in the water supply. It may not effect one person but it my bother his child or someone who is immunocompromised. So by switching to the Chloramines they thought that they were going to bet a better process of sanitizing and less health effects. Unfortunately there are now more disinfectant by product toxins in chloramine water then there was in chlorine. Several articles have said that there is a problem with chloramine dezincifying the brass fittings in home. It’s pulling the zinc out of the brass coagulating in the lines (plugging it up) and restricting the water’s flow. Also when you are pulling material out of the brass, you are opening up a flow path for the water so you are getting a pin hole in it.
Back when I heard that Iowa City was getting there new water plant they were going to switch to Cloramines even though they didn’t have to. I got a hold of http://www.calgoncarbon.com/ one of the largest manufacturers of carbon in the United States. I talked to a tech service guy there I asked him why they would be making the switch. His reply was its simple, it’s a bypass for the emergency plan. When you have large chlorine containers and if a tank ruptures it creates a gas that goes into the air and you have to evacuate. You don’t have this issue with Cloramine. He said that was the main reason why the EPA said to switch, “because it’s safer”. However there are more issues now with Cloramines in the homes.
We has a specific unit the CSR1100 that uses a Kinetico exclusive media called Sulfaban™ which is a type of a catalytic carbon (its a process that the carbon goes though how they heat it up to prepare it for this absorption/filtration ) to filter out Cloramines. It doesn’t last as long as carbon does. Its more expensive to produce/replace but when you have specific needs for it (i.e. Iowa American Water supply) we have a unit that doesn’t use electricity, no moving parts, it’s simply a flow though filtration process and removes Cloramines for the hole home for the customer. You use this in combination with a water softener. You would put this ahead of the softener so you can get the benefits of removing the cloramines because it can damage the resin inside of the water softener tank.
