Automotive vs. RV antifreeze
Can I use regular automotive antifreeze in the black and gray water tanks and sink traps or must I use the RV antifreeze? I am in NE AR and only blow out the water lines to winterize our MH.

Scott you are completely wrong. From the EPA, "Antifreeze is toxic to humans and animals. Waste antifreeze contains heavy metals such as lead, cadmium, and chromium in high enough levels to potentially make it a regulated hazardous waste, so most states strictly regulate antifreeze disposal."
Do you want that stuff in your water system or environment? It is totally irresponsible to dump any amount down the sewer.
I did not know that, that is why I asked. I will be using RV antifreeze and hope for the best.
AS mentioned the pink stuff is MUCH cheaper. And with it. Your traps will be in no danger at all. First it won't freeze solid and expand. Second. You quite possibly could do with out it any way, as expansion is what bursts the pipes, and with BOTH ends of the traps open. Whatever is in there will have room to expand into the empty pipes. Like everything in nature. Expansion follows the path of least resistance.
