WellMATE tANKS

WELLMATE composite tanks have become the tank of choice in residential and commercial applications for their unmatched performance over steel. They contain no steel, so they can’t rust. They require little or no maintenance because their fiberglass-wound and epoxy-resin-sealed outer shell won’t dent, and there’s no paint to scratch or touch up. Their light weight (less than half that of steel tanks) makes them quicker and less costly to install. Plus, they are 100% lead-free, and will not introduce undesirable chemicals or elements into the water.
