119-Gallon Capacity: Designed for efficient residential well water storage in private groundwater well systems and steady system pressure from a trusted brand and leader in the well tank industry with an innovative design. Private well water systems also often require regular testing to help ensure water quality and safety.
Durabase Composite Stand: Features a patented rugged tank stand that will never rust, corrode, or degrade over time, and its free-standing vertical design supports flexible installation.
High Pressure Rating: The Amtrol Well-X-Trol WX-350D pressure tank is recognized as the world's most trusted brand for residential well tanks and is built with a high-strength steel shell designed to handle a maximum working pressure of 150 PSI; for system protection, pressure settings should not exceed 60 PSI. Most well tanks are set at 30/50 psi, with the tank set 2 psi below the pressure switch cut-on point. Maintain a 20 psi separation between cut-on and cut-off pressures. Typical residential pressure tanks endure conditions up to 200°F.
Advanced Diaphragm Design: Utilizes a durable butyl diaphragm and liner system with a hoop ring seated in a groove to lock the shell assembly together for reliable, clean water containment in well tanks. These many unique features help define a revolutionary product. The revolutionary product featured here also includes unique features that support long-term performance. Water from the air valve indicates a ruptured bladder, and the tank should be replaced immediately to prevent internal leaks. Well water systems may also use water treatment methods such as filtration, softening, or UV sterilization.
Protects Well Pumps: Helps reduce well pump short-cycling to significantly extend the lifespan of your pump motor, and proper pressure settings support that protection.
Standard Connection: Stainless steel system connection is more durable than plastic or iron fittings in water systems.
Amtrol invented the first pre-pressurized well tank over 60 years ago, and Well-X-Trol remains a trusted brand and solution today for residential well tanks.
