Hello, @though!
I am a product designer here at Rachio and wanted to pass along the official statement that we have from Sharkbite. I looked into this before we decided to recommend Sharkbites, but thought I was the only one that would notice the warranty wording. WRONG. There are other detail-oriented irrigation nerds out there, just like me! I’m finally not alone.
From Sharkbite: “The UV referenced in our warranty is related to PEX and our plastic barb fittings. SharkBite universal fittings (the ones recommended for the flow meter installations) can be used outside without issues of UV exposure.”
Please let me know if you have any other questions.
Best,
Piper
