What it is

The RWC 100 Ltr Potable Expansion Vessel is a potable water expansion vessel listed for use with Popular Cylinder Spares cold water inlet controls. It takes up the expansion of heated potable water within an unvented system, limiting the pressure rise that would otherwise be transmitted through the cylinder and pipework. The part is identified by the number XVES050110.

Signs this part needs replacing

  • The pressure relief valve on the cold water inlet control discharges during heating cycles
  • System pressure rises sharply when the cylinder heats, or drops again once it cools
  • Water appears at the air charge valve when the valve cap is removed
  • Pressure is lost repeatedly and cannot be held after recharging the system

Before you order

  • Confirm the existing vessel is a 100 litre potable expansion vessel and that this capacity is the one required
  • Check the vessel is being fitted to Popular Cylinder Spares cold water inlet controls
  • Check the connection arrangement and available space against the vessel being removed before ordering
