This procedure can most easily be added to step 3:

B1. Open solenoid valve.
B2. Check LP side is at desired level (e.g., 30 psi).
B3. Close solenoid valve.
B4. Wait 10-15 mins; check LP gauge hasn't increased more than 1-2 psi.

C. (carry on the rest of step 3).
I noticed that when my solenoid turns off. The next day my LP gauge has gone up about 2psi. Should I be worried about this situation?
