Finished DIY gunite pool, problems?

[y0manda]

OK I found the leak in my spa this morning when I woke up and noticed that the spa had drained again and the level of the pool was about 1/8" lower than where I had marked it last night before going to bed. so 8 or so hours later the spa had drained to the seats again and the pool 1/8" lower. The temperature here at night probably stayed in the mid 60's and the water temp in the low 80's. I drained the spa into the pool and removed the drain/pump covers and on one of them There was a nice gap between the two pipes where it wasnt filled in with plaster after inspecting the light nitch and the other drain/pump cover this one that had the gap between the two pipes really stuck out so I filled the spa just above the gap and was watching for any debri getting sucked into that crack. I didnt have any food coloring so I used Red gatorade (which didnt work) ran back and kept watching and then I saw some small debre getting sucked right into that crack between the two pipes. So today I am going to call the plaster guy and let him Know what is going on. Is there anything I should expect to hear from him or what he SHOULD do about this problem. I don't want him to mickey mouse something and say it's fixed. What should I make sure he does to fix this problem the correct way. Also should I now be concerned about the other fittings they way they plastered around them in the pool hence they opened the door to this type of problem? Thanks for any replies!
