60022 Thermal Expansion Tank, Steel, 2.1 Gal., 3/4 In. Connection

When water heats, it expands. Without proper accommodation for this increased volume, pressure builds within your water heater and supply lines. The Eastman 60022 is a pre-charged steel expansion tank designed to absorb the increased volume of water created by thermal expansion, keeping system pressure below the temperature and pressure (T&P) relief valve setting and protecting your plumbing system.

This tank is used on gas, oil, or electric direct-fired residential water heaters and hot water storage tank applications. It maintains balanced pressure throughout your water supply system by keeping system pressure below the T&P relief valve setting. The pre-pressurized design means it arrives ready for installation, and its field-adjustable construction allows customization to your specific system needs.
