Ok, so this was more of a warehouse or industrial environment
than what I was thinking a residential.

Yes, live and learn.

Don't know if I mentioned it here but I recently had a customer
with a 100,000 sqft warehouse decided since the previous tenant
moved out it would be a "good idea" to power wash the entire
building from the top down.  Fortunately no dispatch of the trucks
just a LOT of troubles.  Turned the system OFF for about 5 days!!

It has since been decided it was NOT a good idea!!
