I always thought the pipe going into the expansion tank Iain a syphon type set up so it fills the tank and sucks it back up when it cools and as long as it doesn't run dry the syphon won't be broken, which allows built up crap to fall to the bottom and not be sucked up, so it the pipe was at the bottom it would. That make sense ?
That is the way it works on the Se6/6a. However the pipe end should be near the bottom (as it can't suck back water below it). To stop the pipe pressing on the bottom of the tank and getting blocked, it's important that the end of the pipe should be cut on a slant, that way the pointed end will touch bottom first, and holds the opening a short way up :)
