Pipe Rat - Looks great and should last a lifetime.
Were you hesitant at all to pour the concrete deck prior to installing the liner? I have a concrete block, similar to yours, ready for both liner and concrete - both have been delayed by the constant rain here in Ohio.
I did basic pressure testing on my plumbing, to about 15 lbs, and no leaks so I feel pretty comfortable I won't ahve issues. I might have a chance to have the concrete done over the next week, then the liner 2 weeks from no. Otherwise, I wait 2 weeks for liner and then concrete after that, and with the rainy summer we have that might not be until end of Aug.
Most people I talked with recommend installing the liner and running the pool a day or two prior to concrete just in case you have leaks.
