That's the odd thing Norm, its really hard to get the kitchen to do it. Hot water only. Kitchen is the furthest away from HWS, bathroom closest
I have done a similar thing but with zinc paint in the past. I get up the ladder each year with a leaf blower and give them a good shoot out and then check for any bubbling. Easier now with the husky I picked up - 1 pull start at the top of the ladder and next to no vibration.
Definitely handy to have a sparkie in the family. Have you ever had the high water alarm come on?
