WICOR Industries Water Systems Group has added 40-gallon and 48-gallon models to round out its line of Signature 2000 fibrewound pressure tanks. Every signature 2000 tank utilizes an FDA-approved air cell that's resistant to chlorine and will not promote taste or odor problems often associated with iron bacteria that may be present in the water supply. Each tank is wrapped with more than three miles of overlapping, continuous fiberglass strands, sealed with high-grade epoxy resin and oven cured. The composite construction means tanks that will not rust, corrode, dent or scratch. WICOR Industries Water Systems Group
