It is obvious what it is. Unless you have a kooldeck, the pavers around the edge of a pool can get so hot in the sun that walking on them is painful. Whoever did this decided to tap that heat to cool the concrete and heat the pool. He probably got the idea from those hydronic floor heating systems and figured it would work in reverse. As to whether or not it would work well depends on the interface between the concrete and the water in the piping. Heat rises, and concrete is only a so-so conductor of heat so I'm not sure it would be tremendously effective. However, burnt feet are a strong motivator.
Best answer so far.
That is not likely to be sprinkler. PEX is rarely to never used for sprinklers. PEx is expensive and the flexibility and curvyness woudl be a detriment rather than a benefit for a sprinkler system. It would have to switch back to PVC to connect to heads. That manifold is either for heating or cooling something. Since it is red, that is supposed to mean hot water (blue pex used for cool water). There is no law saying that you cannot switch colors, but odd are good that this manifold carries heated pool water to warm something. Could be the deck, the sides or bottom of the pool. It could be a deck cooling system, but technically,they should have used blue, but red pex could be what they had left over, or what Home Depot had in stock that day. I wish that we had done that. When we heat up the pool in the winter, your feet can freeze to the concrete when you get out if you do not move quickly.

Thanks for all the help, now comes the question.
how can I verify this? what test can I do?
I would bet credits to navy beans (old star trek quote) this is whats causing my leak
You have hired some clueless people to fix your problem. Fire them. Get someone who is competent. If you have to instruct them what a system like this is, and how to find a leak, from info that we provide, you have it back aswards. THEY are supposed to be working for you. If you have to instruct them how to do their job, you can be sure it won't be a professional fix.
The pipe comes from somewhere. Have you found the source?
YOu might cut into the feed to the manifold put in a tee. Turn on the pool pump and see if it pressurizes. If not connect a hose to it. Pressurize it and see what happens. Air would work too. Turn it on slowly so you dont cause great damage if something pops. Throw in little food coloring if you think it might be draining into the pool.
I am very skeptical of a deck cooler heater as it would virtually certainly not work and there is a much simpler solution in Kooldeck which limits thermal transfer to the feet.
You might also consider taking the pictures and question to the pool school...
I'd recommend that you spread a lot of PVC solvent around the visible joints. It won't do anything for the leak but if you use enough of it you won't care anymore.

I briefly checked into getting Kooldeck and was told the type I had was no longer being made. Environmental boondoggle or some such was the story given. I decided to live with the crack in ours.
is that the pool has a solar deck heater, where all the small hoses run through the concrete of the deck and gather heat from the deck to heat the pool water.
which makes sense, why I have a leak, and who no one was able to find it.
so now comes the way to DISABLE it. or fix the link (which may be WAY more expensive then I care to want to pay for a passive pool heater, that doesn't really do anything)

Cut it off at some convenient spot leading to the manifold. Pick a spot where you can easily repair it if it turns out in the end you need to. Turn on the pool. If water come out the inlet pipe then cap that. If it come out of the manifold assembly you did the wrong end and go cut the other one.
When you think you got it leak test.
