Most of us sanitize our fresh water tanks when dewinterizing. I just did this, added a little chlorine bleach to the tank. filled it up, ran all the faucets until the antifreeze was gone and I could smell chlorine. Now...I wanted to hitch up and drive around with the bleach mixture before dumping itbut, for lack of a good explanation, I have not been able to! My question is...will the bleach mixture damage the water pump and toilet gaskets if I let it sit for a couple of weeks?
