What it is

The ACV 557A7006 is a 10-litre expansion vessel. An expansion vessel accepts the change in water volume as a sealed system heats and cools, which limits pressure swings across the circuit. This unit is listed as an ACV spare under expansion vessels for gas boiler applications.

Before you order

  • Confirm 557A7006 matches the number on the existing vessel or in the appliance documentation.
  • Check that a 10-litre capacity is the correct size for the system.
  • Compare the connection and mounting arrangement with the vessel being removed.
  • Allow for checking and, where required, setting the pre-charge pressure before commissioning.
