I've watched this maybe 20-30x as my gas tanks drum out to the bitter end.
Never happened yet.
I think EOTD is a huge misnomer used to cover up inattention to detail on the part of owners per my posts on this thread.
The performance claims of the single stage SR250 Victors would seem to indicate that no big spurt of pressure should be expected from them. Is that what you are referring to?
I doubt that anyone would really notice a "bubble rate" increase with a 4psi rise in pressure even if they are running 10psi or so.
EOTD implies a sudden and unpredictable rise in pressure. I'm not saying it can't happen, especially with poorly designed regulators that may have sticky moving parts or low diaphragm to orifice ratios. But I'd love to test actual regulator units that have been "accused" of dumping to see what they really do as the tank pressure drops.
As far as I can tell a new Victor SR250-580 is about $250. I assume a -320 would be similarly priced.
Edit: I just found an SR250B on Amazon for $143. VTS-250 were $250. The single stage is getting there in price...
The SR250 isn't often seen on Ebay for some reason. The dual stage used regulators are far more plentiful.
Either $250, (plus needle valve and solenoid) or Ebay (plus serious vise and wrench grappling) means no joy for >90% of planted tank enthusiasts.
There's got to be a better way. I'm on the hunt.
