Thank you, I understand now. However, the one time the seal came adrift for me was when I was lifting the malt pipe at the end of the mash, before sparging.The bit I did not explain well was that the wires only go in after sparging.
I put them in place while the pipe is hanging clear of the bottom.
(I have never had trouble with the seal falling off before this point).
Not the easiest thing to photograph - hope these help.
