Flexible hosing

[rockinter]

Hi,
I recently moved my kitchen cabinet to replace it and found that there was a 1.5m flexible hose connected between the copper pipes. It is about 1 meter away from the boiler. I looked on the net and found that they have 13mm bore holes.

Should I replace these pipes with 22mm copper pipes as it might be restricting the flow of the water returning to the boiler?

Is it not a filling valve

It is not a filling loop (as i can see that on the boiler). It is not connected to any water supply. Just connecting the two 22mm copper pipes together.

When you say flexible, is it plastic or metal braided?

The first question that springs to mind is.............. where the f*ck did you get that ugly git, to which the frog replied "cant remember"

Sounds like it has been done like that as a diy bypass.

I would get a plumber in to check what has been done and whether it is actually doing anything!

Haven't got a pic at the moment. The flexible hosing is metal braided. Basically there are two pipes one is flow and return. On the return pipe looks like someone has put a flexible hose (looks like diy job). I was thinking does it effect the flow rate to the boiler as the pipe is 13mm bore or does it not matter as the pipe is not that long?
