First photo - pressure valve not piped to floor.
Middle photo - pick a direction ground up or ground down. And what's with the random outlet placement.
Last photo - was he running wires or water to the switch?
The delta 208 note reminds of a story where some DIYers I met were complaining how the 'voltage at this place was messed up and fried their stuff when they hooked up a new sub panel...half the stuff was at 210 volts' DUH!!!!
After seeing this I have to go cry now....
