The pool is definitely painted (blue green) and the transverse cracks I mentioned were not intended or planned. They meander in a sort of lazy, curvy fashion all the way across the width of the pool. I mentioned "expansion" joints because they look like they might have served, or do serve, that function.
It's most likely a concrete pool or a gunite that's been painted. How smooth is the surface? Very smooth, or just a bit gritty like a fine sandpaper? Or is there a definite roughness to it? If it's concrete a new coat of paint can do wonders. Ramuc is the only brand I've every used. Have done several Rudd Murray pools (a monolithic poured concrete design) with it and quite a few commercial pools too. It's been the industry standard for quite a few years. A pressure wash or in extreme conditions a water blast (with no abrasives), cleansing wash (degreasing soap), then a TSP (tri sodium phosphate) to neutralize anything, then another rinse is the prep. I prefer the Dawn Blue, although it looks a bit "commercial" sometimes on smaller residential pools.

The deck probably would have dropped the same distance, but it's appearance would have been a lot less unsightly, with relief joints. If you think of the slab as one monolithic pour, it's the corners that are the weakest if anything is undermined. The larger rectangular sections on either end have the better size shape and mass to resist breaking.

However it's too late for that, the level is below the skimmer so I can't operate the pump. I'm gonna test the suction line from the skimmer (that's all there is anyway) and if it holds, great, otherwise I'm pretty sure I know where to dig. Any suction pipe from the ground up is going to be replaced when I put in the new pump anyway. I suppose I ought to cut off the suction pipe from the main drain and cap it while I'm at it, since I'm going to abandon it -- maybe I'll test it first and use dye or watch for bubbles to see if those plugs are holding. Does any of that make sense? I guess if I cap it off and abandon it, what difference would it make?
That maindrain line still being plumbed into the suction side of the pump could be the source of the air. If it's plugged at the drain due to leaking then there's no doubt a source of air. When and if you test it you'll be looking for movement in the water with the dye, not necessarily bubbles since the line will be "charged" with water for the testing. If you empty it completely and paint it, you can just look for water escaping. My impression of all main drain that are plugged is that they are faulty. I actually can't remember one that ended up not being so. Remember when you do convert the return line to suction put a fitting on the end for safety. They usually look something like this:

Oh, by the way, in my first conversation with the builder he gave me the impression that this type pool, with the fiberglass side walls, is typical for them. Can't wait to get your "views", after I have sent you something to view. Oh heck, when can you just fly out? A week from Sunday I could take you to a Chiefs game (v. Broncos). Ha. Ha Ha HA. Ha Ha.... Ha Ha Ha Ha Ha Ha...........................
Hey I'd love to, and appreciate the thought, I got the time. Unfortunately because I'm not working right now. Going back to school, gonna start using my head instead of my back. But alas I don't have the dough. Isn't that always the case, when you have the time off you rarely have the money.
