Hi I am enjoying my 2.5 gal corney keg with a barqs root beer bag in box set up. I carbonate the water to 55psi for 2 days and I leave it as is. I don't drop the pressure at all. I'm serving the water in a mug than add the syrup. I disconnect and reconnect the picnic tap to prevent leaking.
My questions are this. When the water is fully carbonated, will it go flat if I drop the psi to abut 15 and bleed of pressure from the keg?
