I'm sure this has been discussed before and I apologize for not being able to locate either a previous discussion or an entry in the manual index. My wife just had a water backup in the kitchen sink on our Big Country 3155RLK. She swears the #1 tank valve was open, as it always is, but when she went and drained the #2 gray tank it was full. We were under the impression that the #1 gray tank took the kitchen sink, #2 gray tank took the shower and bath sink. Are we wrong or is there possibly another problem?
