I am in the process of fitting all new rads in my house and I am adding a new
radiator in the utility room.
Rather than branch off existing rads I cut the flow and return (22mm) pipes.
I then drained the system and tried to solder the new joints.
Unfortunately they leaked. I could not get all the water from the system.
I opened up all the draincocks on the downstairs pipes and left the system for
three hours. The mains feed to the header tank was switched.
Admittedly the pipes were only dribbling but enough to stop the solder.
I got over the problem with compressions although I was wondering why both ends of
each pipes would not stop leaking water?
Did I need to draining the coil down?
Any suggestions please?
