Hello Todd, How are you going to get a pit waterflow signal? Depending on the elevator code it will be required and is not allowed to trip for anything other than the pit head flowing water. I have not found a waterflow switch to use for this. That said in the same situation we have fed the pit head from the wet system on the first floor Control valve and flow switch are on the first floor also, Route the pipe down the shaft to the head location. What you are describing is not allowed by any of the elevator inspectors around here I have had dealings with.
