Welcome to C & M Water Systems. Carl & Maryanna (Sally) Kizer started the business after running an air conditioning business for 10 years, and a solar water heating business for a few more years. Though they were each successful in their own right, there was something that each of them lacked. One of the air conditioners that we sold used water to help cool the refrigerant in turn cooling the home, and the evaporative coolers used water to cool the pads. In the solar water heater panels, water ran through the copper coils to heat the water going into the water heater. In each of these cases, the water eventually started to build-up calcium & magnesium on the A/C copper tubing, cooler pads and water heating tubing and elements which in turn reduced the flow of water and the efficiency of the systems. Hence, the water treatment business was born. We realized how bad the water was in the Yuma area so we started C&M Water Systems in April of 1984 mainly to eliminate the hardness (calcium and magnesium) from the water, having a reverse osmosis system in peoples homes was an extra benefit to them. Now they had soft water that reduced the use of soap products by half and then they greatly reduced the cost of the maintenance and replacement of their water use appliances. Now they also had pure drinking water at their own kitchen sink which eliminated carrying those heavy bottles. How great is that! Why do the carrying when you can just go to the sink and turn on the RO faucet to get a glass of pure drinking water. We can also run a line (in most cases) to the refrigerator to get pure ice and cold water. Call us for an estimate to install complete water treatment in your home today.
