New old pool with new house

[pearsont74]

Hello- bought this house not too long ago and slowly trying to figure out the pool that was obviously custom as it was one of the show houses for this neiborhood build in 1970. I have recently replaced the old brass valves with new ball valves. there are 3 return lines that go to 7 return jets. the pool have a seating area in the deep end with 2 jets and 2 holes in the deck, ports or something. if i turn on those jets, water comes out of the top along with coming out of the jets in the pool??! so i keep them off but i want to see if anyone can explain what we are supposed to do and what is missing as the holes are threaded so i can screw in a cap but i assume something else was there.
Thank you
Ill try to attach pictures
