What it is

The McDonald Water Storage WU18EV is an 18 litre potable expansion vessel. It is fitted on potable water systems to accommodate the expansion of water as it is heated, limiting the pressure rise within the system. The vessel is supplied under the McDonald Water Storage part number WU18EV.

Before you order

  • Confirm the existing vessel's part number and capacity match the WU18EV and 18 litre figures.
  • Check the pressure rating of the vessel is suitable for the system it is being fitted to.
  • Check the connection size and mounting arrangement on the existing installation before ordering.
  • Confirm the vessel is intended for potable water use on the system concerned.
