Gonna get back into it a step at a time. Current symptom(s) is that the drip continued well after the pressure was released (2-hours). There was a visible puddle beside/under the tank and that puddle disappeared within minutes of the tank being drained.
I first thought I might have over pressurized the system when I added water. I did not use my regulator, but had the fill valve open when I opened the faucet and only opened it a "smidge" to trickle water in. Closed off the faucet before the fill valve too. Now it appears that the tank itself may have an issue or at best the lower exit line.
On a lighter note, we "went-campin'" yesterday evening. Just drug out the lawn chairs and set up our table under a tree in the back yard and commenced to toast The Good Life. The dogs acted like we were at a campground but without the leash-law. It was a hoot. Not quite the ambiance
of Lake Guntersville SP and the power wasn't "free", but the setup was a lot easier.
