Sharkbite cap, Identifying a Pipe Fitting

[WorldPeace]

I was wondering about this fitting's purpose. It's located on the cold water line before it enters the tankless water heater.

Is this a cap? What is its purpose?

(I'm guessing that it used to be the line that supplied that steam boiler. But, if that's the case, it was supplying cold water to the steam boiler which isn't recommended/allowed.)

That's an old line to some other location that was cut and capped with a push-to-connect cap. E.g.:

That capped stub could be for future potential pipe to something new.

Thanks! I didn't even notice it was a Sharkbite fitting. You've got a good eye.

No problemo. I added it back, in case anyone was interested.

I accidently deleted the photo when I was trying to full size it.

NO COLD WATER into a steam boiler? How did I get by all those years and installations?
