Sorry, meant to post in a different thread!
For what it's worth, i have check valves and don't have a problem...when i want to drop down from 30, i end up shutting the valve on my tank, bleed the corny (should bring reg to zero), back out reg screw, turn on tank, and adjust up to serving pressure. Some regs do creep, so you might be stuck there
