Need help, snapped coupler thread off plastic supply line
Excuse my newbie-ness and apologies if I use the wrong terms for things. Doing a small bathroom reno, removed old vanity+sink, etc. Stupidly tried replacing old sticky cutoff valves with new valves.
When I turned the house water on, the cold pipe+valve did not leak - yay. But there was a small leak from the hot pipe+valve, so I did something really dumb. I tried tightening the valve nut really hard with the water pressure still on. You can guess what happened next. CRACK! WHOOSH! Instant fire hydrant.
Now my house water is off -- trying to get a plumber in but so far no luck, so thought I'd post here. Please see attached pics.
What should I do? What is this plastic threaded thing at the end of the (orange) hot water pipe, how do I get it off (it seems glued/cemented in place), and how do I replace it with something so I can put a new cutoff valve in place? Until I do I cannot turn on my whole house water or else it will spew out this pipe.
If I were walking into Lowes/Home Depot/local indie shop, what would I say I need (besides a new cutoff valve, since the old one is now jammed with the bit of plastic that broke off).
