Thanks for all the comments! It seems like there are a lot of factors that can contribute to free flow and PSI may be one of them. But it doesn't seem to be a notorious precipitating factor based on what I am hearing back from the community.
The PDF was too long to read so I can't comment on it. The UK tanks are 232 bar or 300 bar. US are 200 bar or 3000 psi. We (UK) have plenty of cold water and zero problem with our standard 232 bar tanks.
I think you can safely ignore the fill pressure as a factor.
