Hello,

A relative has an outdoor tap. The walls and floors are concrete so
difficult to drill (non-sds), so whoever fitted the tap took the easy
option of drilling through the upstairs wall (there are no pipes
downstairs on that side of the house) and dropping a 15mm copper pipe
down the outside of the house. It was lagged but obviously not enough.
There is a "tear" in the pipe where presumably the water froze in the
winter. The repair has been one of those things no-one has got round
to for several months!..


I would replace the whole drop with black HDPE pipe. That won't care if the
water inside freezes.
