44 Gal. Water Pressure Well Tank

Amtrol WX-250 Well-X-Trol – 44 Gallon Pre-Pressurized Well Tank

The Amtrol WX-250 is a 44-gallon pre-pressurized diaphragm well tank designed for use in residential and light commercial water systems. This model is built to reduce pump cycling, maintain consistent water pressure, and extend the service life of system components. It is suitable for installations where higher drawdown capacity is required.

The tank incorporates a seamless butyl diaphragm and a non-corrosive polypropylene liner that isolates the water from the air charge. This design minimizes air migration and ensures reliable long-term performance. A precision steel shell and corrosion-resistant connection enhance mechanical integrity under fluctuating pressures and harsh conditions.

Engineering Features

• 44-Gallon Total Volume – Provides increased drawdown for systems with higher demand.
• Butyl Diaphragm – Seamless design resists microbial growth and deformation under pressure.
• Virgin Polypropylene Liner – Maintains water quality and resists cracking, flaking, and delamination.
• Welded Steel Shell – Fabricated using deep-drawn steel and proprietary welding to eliminate stress points.
• Corrosion-Resistant Connection – 1" NPT steel connection with protective coating for long service life.
• Pre-Charged at Factory – Set to 38 psi to match standard 30/50 pressure switch cut-in settings.
• Exterior Epoxy-Polyester Coating – Baked finish protects against environmental and mechanical damage.

Installation Notes

The WX-250 must be installed in accordance with local plumbing codes and manufacturer guidelines. Ensure the base is level and capable of supporting the full tank weight. Charge adjustments, pressure switch coordination, and thermal expansion control (if required) should be completed during system commissioning. Installation by a licensed plumber or water systems contractor is recommended.
