20 Gal. Water Pressure Well Tank

Amtrol WX-202 Well-X-Trol – 20 Gallon Pre-Pressurized Well Tank

The Amtrol WX-202 is a 20-gallon pre-pressurized diaphragm well tank engineered for use in potable water systems. Designed to regulate system pressure and reduce pump cycling, this model provides consistent water delivery and protects system components from hydraulic shock and wear.

Constructed from high-strength steel and featuring a seamless butyl rubber diaphragm, the WX-202 isolates the water chamber from the air charge to prevent saturation and maintain pressure stability. Its inner liner is made from non-corrosive virgin polypropylene to safeguard water quality and extend service life.

Professional-Grade Features

• Heavy-Gauge Steel Shell – Fabricated to withstand long-term system pressure cycles and environmental exposure.
• Butyl Diaphragm – Offers low permeability and resists bacterial growth; conforms seamlessly to the shell for uniform pressure distribution.
• Polypropylene Liner – Prevents flaking, cracking, or leaching; compatible with NSF/ANSI 61 potable water standards.
• Welded Construction – Precision welded using exclusive deep-draw forming to eliminate stress points and interior weld ridges.
• Factory Pre-Charge – Set for common pump cut-in pressures to streamline commissioning and reduce field adjustment time.
• Corrosion-Resistant Inlet – Threaded steel connection coated for resistance to aggressive water chemistry.
• Exterior Finish – Baked epoxy-polyester coating protects against rust, abrasion, and impact damage in utility or well rooms.

Installation Considerations

This tank must be installed vertically and supported on a flat surface capable of handling the static load when full. Placement should allow accessibility for system pressure adjustments and air charge servicing. For code compliance and proper system performance, installation should be performed by a licensed plumbing or well system professional.
