Eastman 6002 Series 2 Gallon Thermal Expansion Tank, Rough-In Water Heater

Eastman 6002 Series 2 Gallon Thermal Expansion Tank, Rough-In Water Heater

The Eastman 6002 Series is a 2 gallon thermal expansion tank engineered for rough-in installation on residential water heater supply lines. This listing covers the 6002 Series family, available in Model 60022 and Model 60023 configurations, both built around the same 2 gallon tank capacity. As a closed-system component, the expansion tank absorbs the increased water volume created when water is heated inside a closed plumbing system, helping relieve excess pressure at the water heater and at downstream fixtures throughout the home. Plumbers and contractors installing or replacing a water heater in a home with a closed system — meaning a check valve, backflow preventer, or pressure-reducing valve is present on the supply line — will use a tank of this type to accommodate thermal expansion and reduce stress on the water heater tank, fittings, and piping. Whether you select Model 60022 or Model 60023 within the 6002 Series line, the shared 2 gallon capacity and rough-in application make this tank a dependable choice for new construction plumbing rough-in or a straightforward water heater replacement project.
