Thanks so much, I will definitely take a look at leaktools. I wish I could test my own lines, I just don't have the expertise or knowledge to do so. Yep, maybe the valve jiggling contributed and whatever had potentially been semi- damaged by the high pressure was then broken fully by water hammer. A series of unexpected bad luck problems. I agree, if I can't see the water, it's going somewhere and that somewhere has to be into the ground. I see no wet spots around the pool itself. I can only run the pump about two days, 4-5 hrs, and then it's down to the skimmer and sucking air and I have to add water. It's not a HUGE amount of water, but clearly, a leak somewhere. I'll update on what happens!
