Hi,
I'm a licensed plumber in Texas. I am doing a top-out on a 2 story residence that calls for a recirculation loop. When we did the rough in, we ran the return line under the slab. My question is, since this is house has a second story bathroom, should I continue the return line from under the slab all the way around the second story bathroom and then return the the water heater (in attic). Or, should I sent my first floor return to the heater alone and run a new loop with an individual return for the second floor? Or does it matter as long as I put check valves in on each return before the pump? All help is much appreciated.
