I had actually been thinking about building one of these. Definitely a great solution for lower to no oxygen dry hopping for pressure capable and non pressure capable fermenters.
Looks like those guys have been reading a certain thread on HBT...
Couldn't agree with you more but wouldn't this device not replace the PRV on a Spike CFX?
On an SSB Unitank that would unfortunately be the case so hopefully they will take measures to inform customers of the need for an alternative PRV (I mounted mine on a tee after the shutoff valve at the end of the blow-off arm). If users will indeed heed the warning is an issue by itself...
I'll happily admit to doing almost just that... kind of.I know this has been discussed on other threads in the past, but I can see a serious safety deficiency in Brewer's Hardware hop dropper. It is possible to close the vessel off with no safety release for pressure if the butterfly valve is mistakenly left in the closed position since there is no PRV upstream of the butterfly. Without a PRV mounted at a failsafe location on the fermenter, someone will at some point in time inadvertently leave the butterfly closed, thus leaving the cap-mounted ring-pull PRV isolated from the internal fermenter pressure. It can't relieve pressure it's not in contact with.
Plus, for a pressurized fermenter that is used to spund and undoubtedly cold crash, that cap mounted PRV is not capable of preventing negative pressure relief/vacuum break (think "suck back" with nothing to suck in except the sides of the fermenter). Negative pressure during cold crash can cause implosion fairly easily. While this would only result in a sticky mess and the destruction of your fermenter, the opposite failure of over-pressure relief can cause a sticky mess, destruction of your fermenter, and possible severe injury or even death. That gives all new meaning to the phrase, "Killer beer, Dude!"
But wait.... what's that I hear from the Naysayers, "It would never happen. Nobody would be that careless or stupid to not position the butterfly to the 'open' position." Nobody would (assuming they were cognizant of the potential danger) unless they weren't. Or got distracted. Or simply forgot or overlooked it. Or got involved with cleaning the site glass after they detached it from the assembly and never remembered to go back and open the butterfly valve. Nobody would, but anybody could, and what if YOU did?
Fixed!
I hope they will sell just the TC cap w/ PRV and CO2 post for those of use who already have a 3" sight glass and valve.
So far all I've found from other sources are TC caps without a pull ring on the PRV. With all the purging to do, I'd really want a pull ring or lever.

Exactly! Thank you.
