Maybe I've got the wrong end of the stick but I thought I had to pay & join DSC to have access to the forum. Not so?
Yes, you got the wrong end of the stick! It's free to join the forum but to join the club fully with all the extras (magazines, welcome pack, extra access, discounts, DOC extras, etc) then you can pay the £25 per year.
Fitted remote reservoir today. Took a couple of hours, most of which was spent fettling a bracket for the reservoir. Was basically a doddle. Total cost approx a tenner, plus labour (mine).
