How do I flush the antifreeze from the water tanks?

Just keep it on it shouldn't be in the tank just the lines I think? I dont do this part but will try to remember to ask my dad. We've always just kept the sinks and shower on until there is no more pink

hook up to your city connection and run water through all your fosets, shouldnt have any in fresh water tanks and hot water tank that is just a waste. .make sure you put the hot water tank plug back in and chang your bypass valve to split the syster.

I just flush it out and run water until your lines are clear.

I add water to the fresh water tank turn on pump and pump till no more pink. Then add more water and pump for a few mins. Then drain tank , add 1/4 cup bleach fill tank and pump some more , sink, tub, till gone then refill fresh and pump till empty. Antifreeze gong and tank sanitized
