Hello
I need to replace leaking solder joints and add a radiator to my sealed system, which is fed by a combi boiler. After reading various DIY advice website pages, they recommend that I should contact a plumber for all sealed system work but state that I can attempt this work if I had an 'open vent' system instead. Is there major safety issues and additional working procedures involved with sealed systems repairs? or is ok for an average DIYer to tackle a sealed system without contacting a plumber?
Thanks Paulo
