A basic design for Ballast Tanks for those that may not be familiar with it.
My info is from the IIRC The History Channel that happened to be on last week.
My understanding of what happened in brief was they were attempting an Emergency Blow and the Valving for the air froze over blocking the air from getting to the Ballast Tanks to displace the water in the Tanks. Then for whatever reason they had no Propulsion and sank to Crush Depth and imploded.
There were more problems that added up to the Emergency Blow I don’t remember exactly.

That’s what I saw too. Ice was the culprit. Who really knows however.
The story I heard is a little different from yours. A valve or pipe ruptured and when they did the emergency blow they could not clear the ballast tanks quick enough, for what ever reason
This is exactly what I have been told from another source who was in the Navy's submarine program.
This explanation is apparently taught in the Navy's submarine training classes. All subsequent submarines have drain valves for their blow valves to prevent such an event from occurring again.
#9 Imploded in a blink of an eye. Pressure set everyone on fire then water pressure crushed everything. All in an instant.
The Scorpion sub had the forward 1/3rd of the ship pushed into the rest of the sub.
