You can always tell when some twat tees a rad circuit in after the cylinder, seen that many times.  |

If the rads leaking its a new rad job, there's no way to fix a leaking rad,

I've got to say rocket that it's a bit of terminology that I've never heard of before.
If that was a exam question I wouldn't have had a clue!
Although I do fully understand what tom is saying about the boiler expansion having no valves on it (a primary safety valve is what the expansion pipe is). 1st T
The pump pulling in water on the cold feed and then depositing it over the expansion is a very common fault on this type of system (fully pump). 2nd T
When the pump is operating on the H/W mode you don't want it having any influence whatsoever on the CH. 3rd T
Don't know if I'm making things more complicated so I'll stop here.
A plumbing firm that I worked for in the 70s would always take the upstairs CH flow from the gravity primary return !!!!!
The reason the gaffer gave was to give the circ's a boost when the CH was on.
You won't find this in any plumbing manual
