reconnecting a radiator

Postby trengilly » Mon Dec 03, 2007 12:56 pm

Sorry if this sounds really simple: when reconnecting a radiator does it matter which valve I open first - the thermostatic or lockshield valve?
And at what point can the heating go back on - is this when the radiator is full?
Grateful for any help.

You should be fine to open either valuve first i dont think it really matters, but im no expert on this and im sure other users may want to comment further. Ive done this many times in the past and never had any problems. dont forget to open the bleed valuve though to let the air out as it fills up. It always best to fill the radiator slowly. EG: fill it then bleed it, fill it then bleed it. Hope this helps.

If you are unlucky enough to have pipes to the rad which airlock easily, it is worth half filling the rad from one valve and then completeing the fill from the valve at the other end.
