Zurn XT-18 Thermal Expansion Tank 4.8 Gallon

Product Description

The Zurn XT-18 is a 4.8 gallon thermal expansion tank designed for use on potable water lines. It is installed between the backflow preventer or pressure reducing valve and the water heater to manage thermal expansion in residential applications. This tank effectively reduces the chance of excessive pressure buildup by allowing water to enter a polypropylene-lined chamber, expanding a diaphragm into a pre-charged air chamber. Key features include:

• Field adjustable pre-charge for maintenance ease
• Durable carbon steel shell with epoxy coating
• Resistant stainless steel connection for longevity

Product Highlights

This diaphragm style tank is essential for protecting residential plumbing systems from thermal expansion. It ensures that system pressure remains below relief valve settings, promoting safety and system integrity.
