Usually when i find a hole, i find a reason it got there. No rub through, nothing flying around to nick the line, no evidence of copper-eating termites. Just a perfect hole in a u-bend.

Just curious if anyone else has had this happen or may have an idea what may have happened.

Coolperfect,

i thought the same thing but there was nothing. That was the first thing i thought but everything was intact, no rub through on the wires plus no evidence of an arc on the bend.

Customer said it was fine last night when they locked up and this morning it was making a noise.

It's a walk-in merchandiser in a deli that has 8 doors. People are in and out of it all day so i believe them when they say nothing was heard last night.

The perimeter of the hole is clean. Almost looks deliberate.

Thats what i said. If i didnt know any better, i'd say it was drilled but there's no evidence of copper shavings.

Where is the oil? If that leak happened overnight there would be refrigerant oil all over the place. I see electrical tape holding the wires together, the black wire that is looped back looks like it has a heat burn.

Nah, that's just crapola. There is literally NO evidence of an arc, burn or anything like that. They said that when they heard the hiss, they hit the breaker for the fans. This closes the solenoid and it pisses out until 0 psi. Hit the breaker again and it repeats. They told me they had a fan problem.

In order to do this intentionally, they would have to unscrew the cover plate, stab/drill a hole in it and not be all freaked out by the 50 psi flying out at them.

rare, copper termites but don't worry they poop out balls of solder that will end up in the TEV

Seriously,
Is it possible there was an access valve that was never soldered in at the factory or field? Looks like the punched hole they use to put in access fittings. Why a fitting on an elbow? Beats me, but it may have held for a long time and finally gave up.
