We have a radiator in the conservatory under a tiled floor. We have a leak in the 15mm copper pipe to this radiator. Digging up the tiled floor is a real problem...can we push 10mm microbore though the 15mm and connect that to the radiator?

We can get access at both ends.

Any advice please

Thank you

yeah, no problem if it goes through and is a straight run,
may need to throttle the feeding rad down to get the flow over distance though
