Not my employee though. A senior care center called couple days ago, said they had an employee they had fired and he turned off the system and they don't know how to operate it. Probably only needed to have the timer turned on and set, they thought. Turns out he ripped out the entire backflow preventer from the copper plumbing pipe and PVC manifold. Took me a little while to figure it all out but I found it and got it going. They were thrilled. Sounds like the guy has caused about 4000-5000 damage so far. Or that actually includes replacing the locks throughout the place.
