Roadtrek antifreeze won't recirculate

[lisalmarshall]

I have a 2000 Roadtrek and have put 3/4 C. antifreeze in the water port behind the seat per the manual. I can not get the pink stuff to circulate and come out the water faucet. Should I add more anitfreeze??
Suggestions?
I drained the lines as the manual directed.
Thanks!

3/4 cup in the fresh water tank? Likely not enough. Try 1/2 gallon. It might take even more than that.

The instructions I have say: Pour 1/2 gallon antifreeze into the main fresh water tank. Turn on the pump and open the sink faucet and let run until it runs pink. Do the same with the bathroom faucet, the shower and the outside shower. Then pour 1/2 cup down each drain and the toilet. You should also do the city water line by sticking a finger into the outlet to open the check valve. Keep pushing until it runs pink.
