EXPRESS WATER Under-Sink & Countertop Filtration RO132-TNK Editorial Review
This water storage tank is a universal unit that will work with all RO systems, and is made in Taiwan. It comes pre-pressurized with 7 PSI and the physical size of the tank is 15 inches tall by 11 inches wide. However, some reviewers have experienced issues with leaks or internal air bag faults, with some tanks failing after only a few years of use. Other complaints include difficulty with following the instructions for filling and draining the tank, as well as disappointment with the quality of the paint and extensive rusting. Nevertheless, some customers found this product to work well as a replacement for their RO water system.
