HELP - potentially toxic lines?

Yikes! Yes, ethylene glycol (auto antifreeze) is toxic. First thing I would do is make sure that is what was used. If you have the container or know the brand, read the label carefully.

Don't panic. Long story, but I have had clients put diesel fuel in water tanks. That's really bad!

Don't drink the water. We generally don't anyway. We find it easy to carry drinking and cooking water bottled. We're spoiled with our well water.

Flush, flush and flush again. If it were me, I would fill and drain fresh water tank and HW tank several times and empty. I would hook up city water line, open faucets and grey water outlet and let them run. I would flush fresh water pump by letting it run for minutes at a time after flushing tanks.

That's probably all I would do, cuz We don't drink the water. If you are still concerned about drinkablity, you should take a sample (after doing all the above) to s testing lab. We have done this for our well water a few times. Tell them your concern and they will guide you.

Most important. Don't panic. It's not a good thing, but diluted ethylene glycol is probably not as bad as the bacteria growing in most water tanks.

Let us know you resolution.

If I learned a single thing from my favorite chemist, it's "the solution to pollution is dilution"

I would hook the hose up, open every tap, open the grey water drain, and let it run for an hour or so. Or longer. What is coming out is effectively just fresh water. If the FW holding tank was contaminated, do the same, just do from there. It won't hurt the pump a bit to run for an hour or two, it's rated for continuous duty.

Agree, rinse the lines for a few minutes and you'll be fine.  Make sure you use the pink stuff next year.

The problem with this is you are going to get the legal departments answer, not the chemistry departments. I don't know how much it would cost to re-plumb a 182G, but "not cheap" is my swag. My answer to rinse and move on comes directly from a chemist.

I would be willing to postulate that it actually happens on a measurable basis, but the owners don't notice, and rinse well and sanitize at the start of the next season, and the newspapers aren't littered with 2nd page articles of dead RVers from anti freeze confusion.

But that reminds me, after rinsing, make sure you sanitize properly.

Thank you all. Had the RPod out this weekend after lots of rinsing and sanitizing. Not worried any longer thanks to great advice from you fine folks. THANK YOU!
