changing rad pipes

[woodpecker7815]

Hi have a rad which I thought had 10mm copper tubing but turns out its 8mm. Can I change this by putting on a 8mm to 15mm reducers as I want to move the rad about 5 mtrs from its current location.

Will this cause any probs in the performance of the rad.

By the way if I wanted to put some isolation valves on to isolate the pipes can I use normal mains hot and cold water ones

Can you not just put 8mm connectors on and extend the 8mm pipe to where its required

just that I had a few lengths of 15 mm left over.
