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.

Key Features

  • Capacity: 2 gallon tank sized for typical residential closed-system water heater installations, shared across both 6002 Series models (60022 and 60023).
  • Series: Part of the Eastman 6002 Series thermal expansion tank line, offered in two model options to fit different rough-in configurations.
  • Rough-In Application: Installed in the cold water supply line ahead of the water heater to accommodate volume increases from thermal expansion.
  • Pressure Relief Function: Helps protect the water heater tank, fittings, and supply piping from repeated pressure spikes caused by a closed plumbing system.
  • Contractor-Grade Component: Designed for use by licensed plumbers and contractors during new water heater installs or replacements.
  • Model Options: Choose between Model 60022 and Model 60023 to match the specific rough-in requirements of the installation.

Eastman 60022 – Frequently Asked Questions

1) Do I need a thermal expansion tank when replacing a water heater?
If the plumbing system is closed, yes. A closed system means there is a check valve, backflow preventer, or pressure-reducing valve on the incoming supply, so heated water has nowhere to expand back to. The Eastman 6002 Series expansion tank absorbs that added volume and keeps pressure spikes off the water heater tank, fittings, and downstream fixtures. On an open system with no such device, a tank is not required.
2) What is the difference between Eastman model 60022 and 60023?
They are the two tank sizes in the 6002 Series. Model 60022 is the 2 gallon tank; model 60023 is the larger 4.5 gallon tank. Both do the same job on a closed system, so the choice comes down to the heater size and system pressure you are sizing for: a 2 gallon tank covers typical residential water heater installs, and the 4.5 gallon is for larger volumes.
3) Will an expansion tank stop my T and P relief valve from dripping?
Often, yes, when the dripping is caused by thermal expansion in a closed system. Each heating cycle raises pressure with nowhere to go, and the relief valve weeps. Adding the 6002 Series tank on the cold supply gives that expanded volume somewhere to go and takes the repeated pressure spikes off the heater and its fittings. If the relief valve is fouled or the thermostat is overheating the tank, the valve itself still needs attention.
4) Where in the piping does the Eastman 6002 expansion tank get installed?
It goes on the cold water supply line ahead of the water heater, so it takes the expansion before it reaches the heater. That is the rough-in position for both new construction and a straight heater swap.
5) Is the Eastman 6002 tank meant for potable water heater lines or for a boiler loop?
Potable domestic hot water. The 6002 Series is a water heater thermal expansion tank for residential supply lines, not a hydronic boiler expansion tank. A closed heating loop needs a hydronic-rated tank sized for the boiler system instead.
6) Can a property manager hand this to a maintenance tech, or does it need a licensed plumber?
The 6002 Series is a contractor-grade rough-in component intended for licensed plumbers and contractors doing water heater installs or replacements. It ties into the cold supply at the heater, so local code and licensing for that work governs who can install it.
