Question on how long RV Antifreeze is effective in lines

I winterized my 5th wheel last fall by blowing out the lines and using RV Antifreeze. Due to various issues I was not able to take it out at all this year.

My question is should I replace the antifreeze with fresh or will it be good for the winter as is. I live about 20 miles south of Pittsburgh so it does get pretty cold here. Was 41 degrees when I got up this morning so the real cold stuff is not to far away.

Thanks!

Dave

Don't forget to add more to the sink/shower traps and the toilet as it does evaporate in the summer,and if it's gone you get tank smells in the camper that can be hard to get out of fabrics.
Good Luck, Mike

Agree with both posts above. Nothing to worry about. Sorry you could not use your camper this year. That's just sad.

2 points. It shouldn't go bad but if you are worried, (2nd point) just get a couple more gallons and rewinterize it. Only costs a few dollars.

It doesn't go bad, it just gets diluted, so if you haven't drained/flushed the system, you should be good to go.
