Amtrol 399607 Well-x-trol WX-200 Pre-pressurized Diaphragm Well Tank with Vertical Stand 32 Gallon

Product Description

The Amtrol 399607 is a pre-pressurized diaphragm well tank from the Well-X-Trol WX-200 series, designed for residential and light commercial well water systems. This 32-gallon tank ships with a vertical stand and features a 1-inch MNPT discharge connection for straightforward installation in standard plumbing configurations. Amtrol pioneered the pre-pressurized well tank more than 50 years ago, and the WX-200 line continues that legacy with field-proven engineering that outperforms older air-over-water tanks in both reliability and longevity. The tank is constructed with a high-strength steel shell rated to 150 psig working pressure, making it suitable for demanding well pump systems where pressure consistency and structural durability are critical. A factory precharge of 38 psig allows installers to set the tank for common pressure switch settings without extensive on-site adjustment. The internal antimicrobial liner neutralizes bacteria on contact, helping maintain water quality throughout the life of the tank. Amtrol uses a hoop ring and groove design to lock the diaphragm, liner, and shell together as a single sealed unit, reducing the risk of liner failure or blowout under pressure cycling. A patented Turbulator water circulator device promotes full water draw and maximizes the effective drawdown capacity, reducing pump short-cycling and extending pump motor life. The tank measures 15 inches in overall diameter and 47 inches in height, fitting standard mechanical room and pump house installations. A max acceptance factor of 0.35 ensures efficient system pressure management. This well tank is backed by an industry-leading 7-year limited warranty, giving contractors and homeowners confidence in long-term performance. HVAC and plumbing professionals installing well water supply systems will find the 399607 a dependable, code-friendly solution.
