Just want to let you know that we were impressed with David’s presentation of the EcoWater systems. He was very knowledgable about the products! Also please give our installer, Sammy, a big Thank You for his very professional conduct during our install on 2/16/09. He was very pleasant, professional, and efficient and it was very apparent he knew his job extremely well! He is an inspiration that he prides himself in his work! Again, thank you and we are pleased with our systems!
