hello
I have a rad, well several actually all on ground floor, hot a top of rad, cold at bottom. From what I've read online seems may be sludged up.(have bled and tapped with plastic hammer).
Im thinking of attacking one first, to see how it goes.
Im wanting to remove rad to flush through outside with hosepipe.
All rads are on thermostatic valves one side and drain off valves on other.
System is pressurised to a worcester bosch 35 cdi 2, fitted about 9 yrs ago.
Can i just close the thermostatic down to 0
and then close system side of the drain off valve at other side before opening to allow water from rad to pass into the drain off and out through hose?
or do i leave drain off valve open through system?
Im just a bit unsure how the drain off valves work to be honest.
cheers.
