Water Heater bypass question

Pink antifreeze came out when the toilet was flushed during the walk through

When they ran the water and you saw the "pink" coming from the toilet, was the camper hooked up to a garden hose or was the on-board pump, pumping from the fresh water tank? And how long did they run the water in the camper for you?

Reason I'm asking, it's possible they put "pink stuff" right in the fresh water tank. If they did, you'll need to flush the fresh water tank too. (which is no easy quick task).

If they just hooked up to a water hose, then the fresh water was just pushing the "pink" on through. But within a few seconds, the pink should have turned to clear water (maybe foamy, but clear), indicating the "pink" was pushed out.

Not knowing your situation, I'd open the water heater and see if anything drains. If it drains "pink", then you'll need to flush it. Start by checking the water heater. Second, open the drain on the fresh water tank and make sure it's drained also, and pink free. if it's not pink free, then you'll need to drain it, and fill it and drain it again, probably several times to get all the 'pink' out.

After being sure the fresh tank is clean and no pink. You can run fresh water, either through the garden hose, or fill the fresh water tank and pump it.

Once everything is no longer running "pink", then open the water heater by pass and let it fill with fresh water.

If you get foamy water from anywhere, there's still "pink" residue, and you just need to keep flush longer. It won't hurt to drink it, but it's just nice to have it all clean out.
