Chloramines and Chlorides
Chloramines remain in the water. That’s good for the company tasked with keeping public drinking water safe from contaminants such as bacteria, which is bad for equipment. States and Cities currently treating public drinking water with Chloramines
Chloraminated waters are more aggressive than chlorine in reacting with rubbers and their derivatives. Rubber fittings and polyurethane fixtures lose their elasticity and are “more prone to cracking” because of the chloramines in the water thus parts corrode and fail at an accelerated rate.

Note that heated chloraminated water is much more corrosive than cold chloraminated water.

Total Chlorine – Free Chlorine = Chloramines
Chloramine levels not exceed 0.2 ppm. If the level is above 0.2 ppm, the corrosion process begins
The dissolved solids concentration in water is the sum of all the substances, organic and inorganic, dissolved in water. This also is referred to as “total dissolved solids”, or TDS. Calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride, nitrate, and silica typically make up most of the dissolved solids in water.
Chloride is a major component of dissolved solids. The use of road salt—sodium chloride, the same chemical as table salt—for deicing is a major manmade source of chloride to surface water and groundwater. Application of road salt in the United States has tripled since the 1970s. Chloride discharge from water softener use, another major source, has not been quantified.
Concentrations of chloride have been increasing in U.S. streams, especially in urban areas affected by snow. Additionally, the presence of chloride increases the potential corrosivity of the water. Corrosion in water distribution systems affects infrastructure and drinking water quality.
