Hi,
It now transpires that the expansion tank in the cylinder was changed 5 years ago because the system could not be pressurised or would not hold the pressure. The plumber who replaced the expansion tank says there could be corrosion in the cylinder (not the expansion tank) therefore the whole cylinder needs replacing? The system was put in new just over 8 years ago. My sister lives in North London. Would appreciate more info/help. Many thanks
