Never done this before but want to take a radiator off the wall to paint behind it. Issue is that we have a low pressure problem with our boiler and I'm worried that disconnecting a radiator will make this problem worse. Is this the case?
You have a problem with loss of pressure in a boiler notorious for leaking heat exchangers that YOU cannot get to. and you wanted to take a rad off the wall, now this may or may not make it worse but you would be well advised to get someone in to check out the boiler before it does something dangerous.
Also Suggesting that you follow the rules of the forum is extremely helpful IMHO.
