Didn't flare it cause the bend I couldn't get the piece up the neck very far. I ended up taking a set of needlenose pliers and driving it into the end and spinning in a circle while pressing. Worked well. Tightened the shit out of it and no more leaks.CorneliusAlphonse wrote:maybe your soft copper got oval'ed a bit with the bending? in which case solder wouldn't be a proper fix either (thought it might work). flaring the copper so it is round again is the better solution
Needless to say I'm running a test whirlpool as we speak!
