My house in Payson, AZ, is known as the Nightmare on Alpine Heights, because everything seems non-standard. Our driveway lights are hard-wired 110 when everyone else seems to have 9-volt. My 2 110 phases terminate in the craziest places...and my drip system uses a poly tubing that is less than 1/2", but more than 1/4". Looks to be about .35 OD. Has anyone heard of this? The house was built in the early 90s. No one up here carries this tubing, and so its a mother to try to repair. I have several breaches and can't even find joiner tubes with this diameter. I did find 1 universal joiner, with a conical barb that will fit in many sizes, but can't find any more. Any help tracking down this tubing, or more joiners, appreciated.
