Cold Tap Water's Gone Again In Phoenix

Each year, as the ambient temperature climbs above 100,the ground gets so warm that "cold tap water" comes out warmer than human body temperature. This year, it took until June - last year it was early May. It makes for a much quicker warm-up time for showers, dishwashers, etc. I miss the cold water during the Summer, but I know that around November, when the rest of the country goes back to Daylight Savings Time, it'll be back again.
