Hello,
today I cleaned out my magnaclean - well worth doing - incredible red sludge & green bits - but I didn't take proper note or pic of valves before I started & now heating stone cold though boiler working - suspect MC still isolated. Should the wide part of the black isolator valves be vertical or horizontal when it is open? - hopelessly amateur problem I realise.
