Is this the thread where we come for DIY advice?
I’ve fitted a new radiator. Yay me!
I’ve covered the connecting pipes in that PTE tape ... BUT THERES A DRIP COMING OUT. What’s the quick and simple solution BeeXers!? Preferably one that doesn’t involve me draining the radiator again cause I didn’t notice until it was full and working again! Doh!

In my experience there's no quick solution to this. Which side of the valve is the drip coming from? Is it the rad side or the pipe side?
If you're replacing radiators you should clean the pipe ends with fine sand paper to get rid of any dirt or burrs. There should be olives on the pipe ends of the compression joints, I'm assuming they're present and correct as you wouldn't have just a drip if they were absent.
If you've put PTFE tape on the threads and the olives are correct and pipework was clean then one of two things is likely to be the problem. You haven't tightened them enough — you need two adjustable spanners to get the correct tightness, one to hold the valve straight and the other to tighten the nut.
So, it's either not tight enough or there's some small debris on the thread.
