leak at bypass valve assembly

[Mikegranado]

I have a GE Smartwater, the by pass valve assembly is leakng from where it connects to the body valve. I interchanged the 0 rings but the same valve keeps leaking. Do I need a new assembly or should I put a bigger 0 ring. Do not know what else to do here. Any advice would be helpful.

Replace the bypass. Nothing you do will stop the leak unless you change the bypass.
