Why Should I Submit a Water Sample?
Why? So you can be sure your boiler is properly protected. (And to keep your warranty valid!) Our Laboratory has expensive testing equipment that provides sophisticated analysis of your boiler water.
Those test results are then run through a computer algorithm that provides you with a customized report so that you can have peace of mind knowing that your investment is properly protected.
If your water test results are not satisfactory, you will get specific instructions on what needs to be done. In some cases, more boiler water corrosion inhibitor is needed, and in other cases, some sediment may need to be flushed from your system. We won’t rest until you are properly protected!
