I checked the connections when I hooked everything up; I am more worried about CO2 or CO emanating from the tank; does water release either co2 or co when it goes over the overflow in the back of the tank on the way to the wet/dry? Or off the surface of the water? I've got a co alarm in my motor home which I will bring into the office and see what happens; I opened the door and got some fresh air in and my eyes stopped burning so something is up; _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
