Host Mammoth Question.
Is there a valve to switch between usING tank water and city water?

Yes to pump check valve. I’ve had this happen before also. Dirt particle or something caught in check valve allows city water to back fill. Running pump for a while cleaned offending particles and seems to be fine since. Cleaned filter before pump just to be sure. Considered adding check valve after pump but have not as yet done that.
