I have created a quick sketch and inserted below. When I installed the WFM I chose its location because:
- it was ahead all of the current valves
- it was after the hose bib that is in the back of the house (so if it was used at the same time zones were running it wouldn’t affect the reading)
- and the fittings are outside as I have a trust issue with the PVC lock fittings and did want a leak or failure in the semi-finished garage
I have installed a drip zone attached to the current hose bib in garage (which is used for winterizing). I wanted to have flow/leak protection on this zone so instead of moving WFM I was going to add a wired flow meter here - just after the backflow preventor but ahead of hose bib. ( I realize this would be ahead of hose bib at back of house).
So I guess I could move existing WFM to the location that I proposed for the wired version, I would just have to get past points 2 & 3 above to feel comfortable. I will admit that the use of the hose bib in the back while the system is running is rare.
I was inquiring so that I know what all of my options are so I can make informed decision.
I hope this helps to clear up my situation.
