I have a cold water pipe running undermy conservatory and running

concerned that it will freez and split. Its a copper pipe with no

I'd probably pull in PEX and be much less worried about freeze-fracturing.

Otherwise, you can wrap all exposed pipe with heat tape and hope, or cut off
water to that pipe and drain it (don't leave water in the pipe over winter)

This is an area I know nothing about personally (So Calif coastal; no
freeze), but I have read that people in freeze areas sometimes leave
water trickling through the pipes.

I guess this would not be PC these days, esp. in areas where water is
not abundant.
