Like most, our water comes from the City into a big plastic tank in the garage and is pump-boosted into the house.
Every year we leave in May or June, and return in 5-7 months. When we leave, the water lines and pump are shut off and the tank is full. When we return the same water from our date of departure sits in the tank. Invariably, the water in the tank is odor free and potable on our return, without boiling. I believe this is due to the water being very clean or, alternatively, us having cast iron guts.
