Expansion vessel stability

[Dodgemonkey]

Hi to all,
I visited a property recently while carrying out my duties as a Property Manager. The place has an unvented HW cylinder installed with a stand alone expansion vessel. My concern is that the expansion vessel sits on top of a 15mm leg - about 15"or more in length - of copper pipework. Joints at each end revert to 22mm. There is no other support or stabiliser, and the assembly wavers back and forth with the lightest touch. Should it be like that?
Thanks for any advice,

Mike
