It's like there's pin holes in the sharkbite
I doubt you are the first one with this issue.

I'm certain local employees from store's plumbing departments will be able to answer.

Might want to get a perfect focus well lit pic. Try to light it up with a desk lamp (not a flashlight) as you take a pic.

I was going with your location, and I have seen this firsthand myself in Nova Scotia.

The big-box "home improvement centers" are full of plumbing parts made from cheap imitation Chinese
brass, or plating which only resembles brass, which start corroding at the first touch of moisture. Many of those parts are made in imitation of
other, better- known and presumably better-made products.

This is not a knock off sharky. It's the real deal. Weather it made a difference on it being on a hot line I don't know. I think it was 8 years ago. Could of been longer. But at the time there were no knock off shark bites. They just came out when it was put in

Any chance there's been something dripping on the fitting from above? It's going to be pretty ugly if SB's start failing on a
big scale. Now I'm glad I've only put in a small handful in "permanent" piping.

Really? The OP (original poster) is in Canada, and I am in Canada, and both the Home Depot and Lowes here both sell genuine Sharkbite fittings. Are you implying stores in your local area sell imitation knock offs, and can you kindly mention which stores exactly so the rest of the readers here can learn to avoid?

Home Depot sells Sharkbite brand but Lowe's sells two different "knock-off" brands of push-fit connectors, "Blue Hawk" (Lowe's in-house brand for generic products like HD's HDX), and "Mueller Proline".
