Leaky pipe, boiler question

I have a leaky pipe through a union coming out of one of my radiators. I was wondering what steps I need to follow to fix this.
Do I need to purge the whole system before disconnecting the pipe? I know this isn't good for the system.
After the repair is made what steps do I need to do to get the system operating once again?
Thanks

What type of system ? Steam or hot water ?

Can you post a pic of the leaky area ?

If it's a union, just tighten it. They are notorious for leaking. Probably not a bad idea to isolate that spot as much as possible in case you inadvertently loosen it first, but like I said, if it's the union - it's just a matter of tightening it.

Its hot water heat, sorry I cant post a picture.
I beileve I can fix the leak. I'm just worried about damaging my pump or boiler.

Thanks I tried

I tried to tighten the union, however it still leaked a little. I was thinking of replacing the union, doping it up and go from there.

I've sometimes been successful just spreading a thin layer of GOOD pipe dope on the face of the union, and tightening it up again. What have you got to lose ?
