G.C. Suggests:
I am thinking that Slytherin himself put an enchantment on the large pipe 
and the entrance to the chamber so only when the snake was entering through 
it or someone who spoke parletongue was opening it then the pipe would 
expand. It would explain alot. Slytherin could have made sure that the 
enterance was always marked by something and that is how the snake appeared 
on the pipe. We all know that Salazar was able to perform extraordinary 
magic and that the other founders didn't know about the chamber so these 
enchantments could may well have been there all that time.
