repressurise heating system with attic conversion?

PWEI

Hi

I was wondering could somebody advise me please?
A couple of my radiators aren’t heating so I bled them and I’m now trying to repressurise the system.
Last time it happened I got a plumber out and he said it’s very easy to do.
There are two black levers leading in to the radiator in the attic that I have to turn left.
I forget which order to turn the levers on and off. The one closet to the radiator or the other one.
Can anyone advise?

They’ll only turn one way. Just make sure you turn them off once the pressure is 1.5 with the system cold

Thanks for the reply.
Which one do i turn first & turn off first?
The one closest to the radiator or the other one?

Dosent matter. Both at the same time. You’ll hear water go through it. When the pressure is high enough turn both back off again

Thanks for the reply. Will give it a go.

Those 2 black levers going to the rad in the conversion are most likely supply and return, and adjusting them either way will have no bearing on the pressure in the system, they are there purely to isolate the attic rad. You need to find the filling loop, and this could well be in the hot press, hopefully labeled. Where is the pressure gauge? Is it on the boiler?

Generally filling loops have to black valves. I assumed that’s what the op was talking about

Adjusting those black levers did something because after I did it, two of the rads that weren't working were fine afterwards.

I just have one radiator now downstairs that isn't heating

Turn off all rads that are working and the one downstairs should start

No disrespect Dtp, I know you know your stuff. I did not realize that both valves were on the same line potentially.
