We deployed several granulated-rubber soaker hoses last year and, while they certainly weep enough water, they’re exceedingly brittle: they kink and break with what seems to be ordinary handling.
The hose ID is much smaller than ordinary “half inch” hose, so I turned some grooves on a chunk of copper tube that’s a snug fit inside:
Slitting a piece of scrap hose (ya gotta have stuff) and clamping it around the hose and tubing holds the splice together against the 90 psi water in the Vassar Farms irrigation system and provides a bit of strain relief beyond the ends of the tubing:
While I was at it I made three more copper splices, because I know they’ll come in handy…
