Howdy folks, first things first. Totally new to pools, so I know -27 things that I should know. So please be patient
Second, recently purchased home in NE PA, which has I'm guessing a1970's concrete Sylvan pool. I suspect it hasn't been completely filled or run in several years. It's a 20x40 pool guessing 10-12 foot deep.
First big question is, I have what seems to be hydraulic pressure forcing water up through the drain. I am HOPING this isn't a sign that the drain has failed and is allowing water to push up through. I have read that there may be an equalizer/check valve that will allow pressure to push through to prevent the pool from floating. Question is, would this be the case with such an old pool?
The pool being relatively empty for an extended period, the original finish was thin and chalky, so I drained completely, acid washed, patched any chips or cracks with PC-11 marine epoxy and applied two coats of epoxy paint. From all my reading I've come to the conclusion that this won't be the end all, and I'll have to refinish in a few years. But before I go whole hog, I want to make sure everything is in order before I do anything more expensive.

Still have to paint the steps, going to go with white.
So the HUGE question I have, the pool decking seems to have sunk.. Knowing nothing about pools when we bought the house, I figured it'd be just break up the concrete and lay down new. But with the pool being empty for an unknown period, and looking closer, I've become concerned that the pool may have floated? Thoughts? I'm worried about it cracking when I fill it? Should I be concerned? Anything I can do to prep for the worst?
The other question I have is the drain and "jets". The main drain is concrete with no screw holes, I bought an SDX concrete retrofit, is that the best way to go?
Also the "jets" under the skimmer have a single screw hole in the center. I can't find any fittings online for them, as I don't know what they are called. Any ideas what each is (inlet/outlet) and what I'll need to cover them?
Thanks for all your help so far... I am certain there will be MANY more questions.
