Maintains consistent water pressure throughout the house when pressure settings are properly set for home use.
Reduces frequent pump starts and stops for longer pump life when the tank is set correctly to match your system’s needs, with precharge set 2 psi below the cut-on point.
Antimicrobial liner helps neutralize bacteria for cleaner water storage.
Durable steel construction provides long-lasting reliability.
Compact footprint makes installation easier in limited spaces, and a liner-based approach can mean lower disruption than full tank replacement when the project is a good fit; the tank should still be assessed before choosing that solution.
The Amtrol Well-X-Trol WX-251 is a 62 Gallon pre-pressurized diaphragm well pressure tank for residential well water systems, with a polypropylene liner designed with antimicrobial protection to neutralize bacteria, heavy-duty steel construction, and a patented Turbulator® water circulator to help maintain consistent water pressure and support efficient system performance. Homeowners looking for a reliable replacement tank, along with contractors and light commercial users who need a durable pressure solution, can use this overview to quickly evaluate whether the WX-251 fits their system. It covers the tank’s key specs, materials, pressure and pump-protection benefits, installation advantages, and warranty details so you can compare it with confidence before you buy.
This floor-stand model is built with high-strength steel and features a polypropylene tank liner, seamless heavy-duty butyl diaphragm, 304L stainless steel system connection for corrosion resistance, and antimicrobial liner protection. It is pre-pressurized to 38 PSI, rated for 150 psig working pressure, and sized at 22 inches by 47 inches. The polypropylene liner creates a barrier between water and tank materials to support containment, help resist corrosion, protect the steel shell, and extend tank life, while in the right case helping reduce replacement disruption when a liner-based solution fits the tank condition better than replacing the full tank. It is also resistant to many chemicals and UV exposure. The liner is rugged enough for demanding use. Built for indoor and outdoor use, it features a Tuf-Kote finish. The patented Turbulator® water circulator device helps improve system performance, making this a reliable solution for well water systems and other pressure tanks where steady pressure, cleaner water storage, and longer pump life matter.
