I'm glad the tatty sump line was there when I went for the first (and thus far only) time as ducking to get into that bit past the rocks to get to the sump looked so unpleasant that I'd have been really reluctant to go in to see if it was where the sump was...so maybe it's a good idea for it not to be there! On the other hand, it's a nice reassurance that you haven't just found some unfreedivable nightmare that you're about to plunge to your death in.
Next time I'll go through but at that time I expected the sump not to have a line on, it was only on here that I found out the bailer twine had been added.
