My returns have been blowing great that past week. This morning, I found that the returns are blowing very weak and the motor was hot to touch. I read somewhere there might be an air leak that is causing the return. If so, I think I found the leak. (See picture) I have a black tube that runs from one pipe to the next ( I think it was for a chlorinator?) That tube is leaking. Since we don't have a chlorinator, should I just remove it? If so, how do I seal back the holes?
And why would my motor be running hot all of a sudden?
