Sanitizing Solution Needed in PRV for Pressure Ferment?

Food for thought. Stuck valve not 2 months ago.

It appears you had an old version of the PRV. I have the newer plastic knob so I have never had an issue.

They don't call it an air lock, it's a PRV! They are just letting you know that it can also operate as an blow-off tube. The only airlock I am familiar with are the for plastic and glass fermenter or should I say the low end devices. Does not matter because I use the titl to read my SG and I use a hydrometer as a backup. The Spike lids come with 3-4 TC ports so you can configure it anyway you want. If you want two or three PRV for backup so be it. I wonder what kind of backup PRV do you use on your clear fermenter? Is it glass or plastic? Do you have multiports in order to backup your PRV?

Adam the engineer at 1120 says " serving as your airlock " it really isn't.
I have a plastic fermenter, it has an additional pressure relief valve and also the seal between lid and fermenter are the points of fail rather than the vessel body.
Blow off tubes are only airlock with neutral pressure or if positive gas production occurs in the fermenter. If this isn't happening then the liquid in the airlock is sucked back into the fermenter and air will be as well. This shouldn't happen with the Spike because the valve is non return.

That is true! Not sure how we got on the airlock conversation but my point is, the Spike all and one PRV, serves all my needs except when applying Oxygen via Carbstone or non-pressure Fermentation. I have also used both PRV as a backup to the blow-off. When I cold crash, i apply psi to keep suck back and to start Carbonation process. I do not have to worry about exposing my beer to oxygen and outside elements changing between the two.

Just leave the lid off and put a tea towel on the top when you open ferment.
Or get radical and use a bucket!

Should you say that? Since you asked—no, I don’t believe you should.
