Amtrol WX-251 (145S10) Well-X-Trol is an Well Water System Pressure Tank (Stand Model) with 62 gallons volume and 1-1/4" female threaded system connection. Precharge Pressure for the WX-251 Well Water System Pressure Tank is 38 PSIG and the Maximum Working Pressure is 150 PSIG.

Heavy duty butyl diaphragm of the Amtrol WX-251 well pressure tank is the thickest in the industry and features seamless construction for uniform strength and flexibility. It conforms exactly to the shell configuration without stretching, creasing, or forming bubbles or corners that could trap water or sediment. Butyl is the best known elastomer to prevent air loss.

Heavy duty butyl diaphragm is extremely resistant to bacterial growth and meets FDA requirements for potable water supply.

Polypropylene liner provides a 100% corrosion resistant, non-metallic rigid water reservoir that is listed by NSF International Standard 61.

Welded air valve is permanently attached rather than mechanically threaded to prevent loss of air pressure and to minimize stress on the well's pump system. It also carries a tamper-evident warning label.

Exclusive welding process eliminates interior rough spots and sharp edges that can damage the diaphragm and liner.

Deep-drawn steel domes offer twice the strength of rolled steel while minimizing weight of the Well Water Tank.
