Dump tanks

[Sharlene]

I just moved from Florida to Ohio and am on a well. My question is why are all my tanks dumping into my black tank. They never did it before

Dark outside but I have 3 tanks 2 gray and 1 black. Everything worked fine while I was in Florida

1 gray for shower, 1 gray for kitchen and bathroom sink and 1 black

I wondered about the valve configuration

Maybe post your year/make/model of RV. I'm not sure how being on a well for a water supply could have anything to do with how your holding tanks are operating. Need more information.

Some sort of overflow? I learned the hard way if I don't open the faucets in the rig before turning on city water my fresh tank will fill up.
