Water leak when trying to use "back flush" system

[wb7sdxgary]

I just bought a used 2006 Keystone Cougar model 304bhswe travel trailer. Everything is great except when I tried to use the heralded "back flush" system. Instantly after I turned on the water hose to back flush the system, I had water coming out of the area where the converter and all the water lines are. (Whoever thought about putting electrical and water hookups in the same space???) Naturally turned off the water and went inside to soak up the water and took off the access panel to look inside. The only thing I can figure out, since I can't really see up to the inside of the back flush fitting, is that the inside fitting is cracked or loose. Anyone know what the easiest way to get to that fitting??? Is it a pex crimp fitting??? I did have a water regulator in line so the too much pressure idea probably won't be the cause. Thanks, Gary Vancouver, Wa.

Broken vacuum breaker or line connection at the breaker. Easy fix and a 5 dollar part if it needs to be replaced.
