Wellmate Pressure Tanks

WellMate's tanks feature corrosion-proof composite construction that require little or no maintenance, plus their light weight makes them easier and less costly to install. All materials meet stringent U.S. Requirements for water components and are NSF and/or FDA listed materials. WellMate continues its tradition of excellence by offering features and benefits steel tanks cannot match.

These rustproof WellMate pressure tanks are made with blow molded, fiberglass wrapped, seamless construction. They won't rust, dent, or come apart at the seams because there are no seams, and a rugged base is included. Full five-year limited warranty with a one year replacement labor allowance.

These tank now features the quick connect that snaps securely into place and is retained by an H-clip.
