You cant use a solenoid with this type of setup as when the solenoid is off the pressure will continuously build up and either burst or leak the system.
What you do is use the solenoid to vent the bottles ie solenoid on a night letting pressure out the system. You just have to cope with yeasty smell when venting.
Or do what everyone else does, just run 24/7.

To be honest I wasn't that convinced it was going to be so effective but I'm pleasantly surprised how well it works. The pressure bounces back and forth between the bottles so citric acid is regularly drip fed using check valves into the bicarbonate of soda to create co2 , as the pressure drops in the bicarb bottle from feeding the tank the higher pressure in the acid bottle forces just enough acid up through the line into the bicarb bottle which in turn reacts and re-pressurises the whole system.Good on you.
Keep an eye on it though!
Hey update us on how long it lasts. Always good to know.

You really ought to have a 3rd empty (or little bit of water) catch bottle before the tank just incase bottle A or B overflows. Any of bottle A or B entering the tank will kill all in the tank.This diagram shows how it works, although this is a slightly different system the operation is the same

I get where you're coming from and I appreciate the concern but it can't happen, it's not like a yeast reactor set up. I've done plenty of them and have that set up down to an art, in my opinion yeast set ups are too unpredictable anyway. Regardless, there are multiple check valves and a high pressure release valve that stop that happening but it's not possible with the setup. Worst that can happen is it dumps all the co2 that's pressurising the system but that would require the needle valve to fail catastrophically and that would result in pressure releasing directly out the needle valve anyway.You really ought to have a 3rd empty (or little bit of water) catch bottle before the tank just incase bottle A or B overflows.

Well that made me smile. Hate it when that happens! 😛You just have to cope with yeasty smell when venting.
