The Water Worker 20 Gal. Pressurized Well Tank is a durable, direct-fit replacement designed to maintain consistent water pressure and extend pump life. Built with deep-drawn steel construction, it features a polypropylene-lined shell to prevent taste or odor absorption. The thick diaphragm keeps water separate from pre-charged air, reducing air loss for long-term performance. This tank comes pre-charged and is designed to retain its charge for years, ensuring easy maintenance and reliable operation.
