We occasionally drink water from the holding tank and always wash dishes and brush teeth with that water. However, we usually buy bottled water to take with us because it’s more convenient when walking/driving.
Bottled water used to taste better than our previous homes city water. But, our water is great at our current house. We’ll have to see if we skip bottled water in the future.
It’s hard to beat good well water at the top of a ridge like we are. There are no properties with a higher elevation to pollute our well.
