We had an issue with our heating vessel which was red (Sealed system) which was corroded so was leaking water.  It was replaced with a grey one. 
Since then we have had further issues with the heating system with pressure going down and I have had two independent plumbers/heating engineers out. Both have said that the heating vessel should be red and not grey.  Surely a colour doesn't matter does it?
I have gone back to the developers whose heating company have said that the red ones are now being discontinued and that the grey ones are now being used.  There is conflicting information here and does this mean that the developers are just trying to get out of their responsibility.
I have no clue with this.  HELP

Firstly name the housebuilder!
How are others going to learn (be warned) which builders are worse without such feedback on this forum?

There are two main types of Expansion Vessel dependent the application.
You will normally find a Red Vessel (Heating Vessels) to be used on a Sealed System Heating.
Blue Vessel or White Vessel (Potable Vessels) are most commonly used in a potable application such as an Unvented Water Heater or a Pumped System.

I have no idea why a grey one has been used.
The "red ones discontinued" comment is a fob off garbage in my opinion.
The make or size might be discontinued but the colour?

Your pressure keeps dropping because you have a leak on your heating system somewhere.
