      Water tank review

      Excellent customer service plus fast shipping time

      David R. (North Battleford, CA)
      Great price for original tank

      This was the same branded tank that originally came with the Watts Premier R.O. system. It lasted 8 years so I wanted the same tank to replace it. Found it at a great price on the Water eStore. Shipment was fast and free.
      Highly recommended. Thanks.
