1. Date should be fine
2. Not necessary but can be great practise.
3. It is not you - if pressure is right, might be warm tower.
4. 38 degrees F @ 14 PSIG if you are 1000' or below.
5. If you are using dish washing detergent, there is a film on the glass reacting to the carbonation.
6. Refer to # 3 and set pressure to 16 PSIG if you are at 38 F.
