Good morning all, yesterday i removed this bute fitting from under a house, from what i can tell the pipe was not fully pushed into the fitting and had been leaking for 8 years! it has corroded the crimp ring just enough to allow it to crack and let the pipe go.
first time i have ever seen this happen! 
this was on town water.
