It’s More Than Just a Well Tank™

Amtrol invented the first pre-pressurized well tank over 50 years ago as a better solution to traditional air-over-water tanks. This revolutionary product featured an innovative design that uses a hoop ring and groove to lock the diaphragm, liner, and shell together.

Today, Well-X-Trol is still the standard of the industry with many unique features including high-strength steel to deliver 150 PSIG working pressure, a patented Turbulator water circulator device, and patent pending antimicrobial liner that neutralizes bacteria on contact.

Well-X-Trol is the world’s most trusted brand of well tanks, backed by an industry-leading 7-year limited warranty.
