Water Chemistry Is Important
Tuesday, September 8, 2009
Recently we received a call from a customer whose almost brand new heater was leaking. We went out to take a look and found that his heater was indeed leaking from the heat exchanger (the tubes the water runs through, whether the heater is turned on or off). With good water chemistry and hydraulics, the heat exchanger should easily out-last your heater. So, we took a water sample and ran water chemistry tests. The chemistry was so far off that the water had eaten through the copper in less than a month. No heater manufacturer warrants against water chemistry damage, so this customer is faced with a very large repair bill.
If you own a pool you can do all pool maintenance yourself or hire a professional to take care of it for you. If you do it yourself, remember that the key elements are chlorine levels, pH, total alkalinity, and calcium hardness. There are a few other tests you will want to run occasionally, but these are the weekly ones. Keep in mind that all the factors are interactive and a change in one may well affect the level of another. If your water is very aggressive it will erode parts of your pool equipment and create stains on your pool surface. If it is scaling, it will cause unsightly deposits on your pool surface and possibly in your pipes and the equipment. Obviously, the goal is balance!
Ideal ranges are generally considered:
pH of 7.4-7.6
Total Alkalinity of 80-120 ppm
Calcium Hardness of 150-400 ppm
