WELL-X-TROL Professional offers more options and sizes than any other well tank manufacturer including vertical, horizontal, in line, and underground in sizes ranging from 2 gallons to 119 gallons so you can configure a system that's right for any application.

WELL-X-TROL Professional tanks were the first to meet all industry standards for quality and safety. The butyl diaphragm in all models meets EPA requirements for potable water as defined in the Safe Drinking Water Act of 1986. The entire tank which includes the virgin polypropylene liner, butyl diaphragm, and acceptance fittings for a 100% corrosion resistant water reservoir is listed by NSF International Standard 61.

• Stainless steel air valve is brazed in position rather than mechanically threaded to prevent loss of air charge. It also carries a tamper-evident warning label.
• Deep-drawn steel domes offer twice the strength of rolled steel while minimizing weight.
• Unique positive hoop ring seal secures diaphragm and liner for added strength and reliability.
• Heavy duty butyl diaphragm features seamless construction for uniform strength and flexibility. It conforms exactly to the shell configuration without stretching, creasing, or forming bubbles or corners that could trap water or sediment.
• Butyl is the best known elastomer to prevent air loss.
• Heavy duty butyl diaphragm is extremely resistant to bacterial growth and meets FDA requirements for potable water supply.
• Virgin polypropylene liner provides a 100% corrosion resistant, non-metallic rigid water reservoir that is listed by NSF International Standard 61.
• Copper-lined acceptance fitting is silver brazed resulting in a watertight and airtight seal.
• Exclusive welding process eliminates interior rough spots and sharp edges which prevent damage to the diaphragm and liner.
• Each finished tank is pressure tested for safety.
• Exterior appliance-like finish looks attractive while protecting the tank from the elements.
