It’s just a pressure relief valve. $10 at Home Depot. Pressure Relief Valve 3/4" 100 PSI for Water Well Pump Pressure Tank Brass NO Lead https://www.amazon.com/dp/B076MB7FK2/ref=cm_sw_r_cp_api_i_1sJhDbJRZ7KDV
Shut the water off at the valve, relieve the pressure to your home, two wrenches to remove, Teflon tape on the threads of the new one and away you go.
This is a pretty common item. You will have an easier time finding an adjustable pressure relief valve than a set 3 psi, but even that isn't too uncommon.
I found this one on Amazon
I use this.
I had to dial it in a bit but using a decent gauge it's not too difficult. When I have it turned to 60PSI it'll hold 20 perfectly, I have a bunch of stuff noted at home from my ~5mins of testing it took to dial it in.
It has held (and allowed to build) pressure on my Flanders Red for a couple months now awesomely.
No need to go insane on pricepoint for something like this, but if you want the kind of precision you got without having to trial and error shit, then go nuts.
OP, I found out what you were looking for is called a spunding valve. It's essentially used to brew beer under a fixed pressure. I found this on amazon , how you'd fix that to a lid is beyond me tho.
​
Edit : Also to note: mason jars cannot hold pressure anyhow, you'd have to bottle your kombucha first and fix on the valve to the bottle cap/cork and set it fro like 30-40 psi beyond which the bottle will explode anyway.
Contains 100psi pump, 4 gallon pressure tank, analog pressure sensors before and after solenoid, flow meter, general shutoff and 3 individual shutoffs.
I'm going to connect an Arduino based board that I've built. It has an Ethernet connection to report pressure and flow data to a remote server.

If you do make a spunding valve I recommend this pressure relief valve. I bought a pre-built spunding valve off of homebrewing.org and the pressure relief valve it came with sucked. I saw this on brulosophy I believe and swapped it out. My current fermentation is the first I've used the new one, but so far it is MUCH better.
I actually didn't tally up the cost as that wasn't really of a concern to me, but I'll try my best to provide links to the things I bought for this. Feel free to add it up for me!
I also bought various tools, like crimpers, Dremel kit, drill, etc, but I don't consider those to be project-specific as I'll have them for the foreseeable future. Let me know if there's anything you see that you think I missed!
You could theoretically drill out the cap of a swing top bottle, and thread one of these into it. It would look weird, but it would probably work.
I have been working on this over the past 2 years. This will be my 4th HvZ game using this rig. We normally have a game in the fall and then in the spring. I got the idea when the magstrike saved my bacon and I wanted to fix the small bladder issue. The speed of them was awesome but pumping it every time was a pain. I looked up some other mods and didn't see anything I liked. I decided I didn't want to the noise of an air compressor so I went with a large backpack mounted tank.
The magstrikes don't fire much stronger than a stock one. I shot them with a stock magstrike and matched them pretty close. Since basically its just a magstrike with a huge bladder, there wasn't much argument against it. I had the mods come personally over to check it out before hand. The fact that I continue to improve on it and make sure it's safe has earned me respect and I even have people referred to me for help to keep them within reasonable limits.
I've worked up a master part list for you with links of where to get most of it too:

This includes all the parts currently being used in the mod. It doesn't count the two magstrikes I broke/parted out from experiments, other gun parts, extra fittings and all my tools I purchased to build the stuff. Most of this was broken up into small purchases over the past 2 years. $5 fitting here. $50 order there. I also purchased mostly things I could use outside of just HvZ like the bike light, ammo pouches, etc so it's not all wasted on nerf stuff.
Not sure what they bought, but if you Google "1/4" npt relief valve 45 psi" you should find something:

Funny this comes out the day all the parts for my spund build arrive. Good stuff! Got the parts in question from the chi company, valve and gauge off amazon.
spunding valve

Nylon Flare Fitting Washers (1/4”)
Stainless Tee 1/4” x 1/4” x 1/4” NPT
Quick Disconnect - gas MFL
Pressure Relief Valve Adjustable Pressure 0-100psi 1/4” NPT
Pressure Gauge 60psi 1/4” NPT
I ferment in 10 gallon cornies and I just built myself a spunding valve to use as a test. Wasn't that hard the main bit is the valve itself, which I got off Amazon.

And then some fiddly bits to go from the Tee to the QD for the keg.
What if you did this:
Fermenting keg > pressure relief valve (set to say 22psi for spunding purposes at room temperature) > oversized tubing that could fit over the pressure relief valve > check valve > co2 keg > spunding valve (like 120-130psi).
Then you could use the co2 keg as a co2 tank.

Would this work? It's rated to 30psi and just needs to be capped on the male end.

This one is adjustable, but needs to be adapted to 3/4".

Thank you both!
I've found the part on Amazon. As a complete novice, best to get a plumber in to replace it I'm assuming?
This is basically what I'm referring to.
You know, like this.
