The product page does state "Vacuum Release" but the manuals or the rest of the site do not include any data on what pressure the vacuum release kicks in. For cold crashing section of the manual it specifically states that CO2 pressure should be added. Sorry for the loss of you conical. I'd reach out to Spike to comment.

Thanks for your input!

Yikes, that really sucks!

I got one from Brewers Hardware that is specced to break vacuum at 1.5 PSI, but I have no idea if the vessel is even rated for that. I'll need to check that.

For the Spike, it is strange that it lists the vacuum breaker functionality but not the PSI. I checked the transcripts of the two videos and they never mention vacuum at all. I wonder if the website should even list that functionality.

They do list it, as 1 PSI.

Looking forward to the details! Let us know how we can help once you have more info.

I just had this conversation with Øyvind Stokkan at Brewtools in the context of the Brewtools F-series unitank and the Brewtools Vacuum-Compensating Safety Valve (PRV). Øyvind chose not to volunteer a vacuum pressure for which the F-series unitanks are rated (simply saying the unitanks are not designed for vacuum) and chose not to answer the question as to the pressure at which the Vacuum Compensating Safety Valve lets air in. In general, Øyvind seemed more concerned with the oxygen risk using the Vacuum-Compensating Safety Valve (versus the standard Safety Valve) than the risk of imploding tanks.

Obviously, this doesn't directly relate to the Spike All-In-One PRV, however, it does offer insight into another (leading) manufacturers perspective on vacuum.
