We selected Thrasher due to information we received from the company rep and also the fact that we knew the company had been around for many years and has a solid reputation. Mike Haye (sales rep) was prompt, extremely professional and provided us a great deal of information in a short time. He did not pressure us. We were very impressed with Mike. Competitive price and the guarantee is important to us. We were pleased with the work the crew did and know it will solve our water problems.
