Went to Home Depot to purchase a new reverse osmosis system, my plumber gave me some specifications. So I looked for someone to ask a couple questions. The first clerk didn't even know what a RO was, the second one did and directed me to the one and only on the shelf. It was a britta. He said that he knew nothing about them and he proceeded to walk away. I proceeded to walk out the door. Went right down to Loews where they had several models of all different manufacturers, and I had some competant help. HOME DEPOT, hire knowledgable employees NOT OLD Grumpy men and young girls with no sense of customer service~
