I have a well, and have often wondered if the quality of my water is as good now as it was originally (25 plus years ago). So, I took advantage of HD Water's free water test offer. Thankfully, my water was not bad in any way, but COULD be made better , and that's what the test (really a battery of tests) showed. The technician/sales rep was extremely pleasant, and made the entire process interesting and informative. I highly recommend all homeowner's invite HD Water in to test their water. You'll find that the results of the testing will lead to a well planned sales presentation, but what else would you expect? There is no commitment, everything is exactly as promised, and very professional.
