Couple upgrades.
I added a water meter so I can monitor how many gallons go through the filters. I put it on the OUTPUT of the filters, so the iron would not deteriorate the meter.
I added a Z-Wave (Smart-things) Valve Control so I can shut the main water off from my phone. I always shut the water off in either house I leave. It's especially a pain in this house because the "Cellar" is in an access door through the kitchen floor.
I also mounted a Blink Camera pointing at the water meter.
30 gallons for a shower for me, 15 gallons for my wife
