"Everett is a very experienced and knowledgeable water guy. My water reeked of chlorine and was very hard (within three weeks of living here, my dog's water bowl had a crust of mineral hardness in bottom of bowl, so I knew the water was very hard). He tested my water and showed me the levels of chlorine (more than a public pool requires) and the hardness grains were approx. 14. I purchased a water softener and conditioner combo unit, and also a reverse osmosis system so as to have safe water for drinking, cooking and bathing, and to save my appliances from the hard water. I was very happy with his workmanship and the products installed. Taking a shower was a delight, no more nasty chlorine smell! Everett even did a few extra items for me, totally unrelated to the install, and I greatly appreciated his kindness and help! I would highly recommend this company for all your water needs! The price was right too! Pam"
