But I have worked out I could use under the house.
I wouldn’t trust irrigation pipe as far as I could throw it, but is this stuff, suitable for cold pressure pipes?
I’d get a plumber to take a feed from before our water filter, then run under the house with one t junction to feed two beds.
I have some other beds, one in the lawn....unsure if I could trench under that. And two more with courtyards but no under house access. I’d rather not go aerial, or surface mount.
