After seeing them on here, I made myself a dosing vessel from a pump up garden sprayer. I can report that you can successfully fill an empty solar system (the hot water type, not the one with planets and stars) with it and pressurise it to over 2 bar.
Worked beautifully, lots of air in the system, but left running for half an hour with the auto air vent open it was running silently and air less.
I did have a boo-boo though. I removed the hose from the pumping station which was full of fluid still, so I squeezed the trigger to release it into the bottle. I forgot it still had just under 2.5 bar of pressure in it and got it in my hair and my right eye! Bloody stung that did!!
Cost me less than £25 to make and it costs me £70 to hire a solar filling machine, not including the fuel and time spent collecting it!
