Sanitizing Problem

[navybanker]

Tried to sanitize water lines using the winterization inlet in the convenience center. Never did pull water/bleach solution from a container. Made sure the pump was primed and working. The winterization switch was on as well as the fresh water tank "fill" switch to fill. City water was off. Is there something else that needs to be done or is this another valve/switch that needs to be replaced like the black tank flush one that was just replaced? I gave up and poured water/bleach solution in the back fresh water tank inlet which is not nearly as convenient but worked. Thanks,
