1) plug in the power for the water softener - unplugged while painting / power washing
2) water heater circuit breaker FROM "save energy" to the ON position - double size breaker
When leaving, make sure the cold water cut off outdoors is in the OFF position
(across the line, not lined up with the water pipe).
3) take a look at the "stink pipe" which stands outside the kitchen window.
It should be upright, not lying down. Bob could try to work that when down there all together.
