First... is when they put the uprights back and the top edge on the pool after doing the liner i noticed today that one of the uprights didnt get hooked right and there is a gap between it and the pool wall. Can I fix this myself?

Second ... when they broke the return line loose to take the liner out and remove the "eyeball" I call it it looks like they might have used a screwdriver to break the connection coming out of the top of the pump head where it returns to the pool .. now it leaks ... I have tried to stop the leak but cant ... anyone have any ideas??? Tried silicone already .. no luck ...
