Thank you, thank you, now I have a plan. Follow-up Question: Is there any way of neatly "trimming in" the copper that will run vertically up each side of the sliding door?
I've got a leak in the concrete slab where the copper tube is routed under a sliding door for my hydronic baseboard.
Can I route the tube over the door and though the drop ceiling, or would it be better to cut the concrete and replace the copper?
