Wow, came out the vent on the roof.
Once I left mine on while i was cleaning up and I was keeping track of it until a friend came over and start chatting and then i forgot about it. I was standing next to my out door sink and I heard a bubbling sound and I stopped and had no idea what was happening but then the sink started filling up, OH NO
and i take off running to shut off the water. The sink did over flow just a little bit, my outdoor sink is hoked to the black i found out then. Needless to say the outdoor kitchen got fully sanitized that go round of cleaning up. DW still nags
me about that opps. I'm just glad it didn't come out on the inside somewhere.
