That spool on the top port of my MT is an additional instrument tee so that I'm measuring Mash tun out and mash tun in (rather than HERMS out, which should be the same as HLT bulk temp).
I don't have any reason why the valve is kettle side rather than the other side of the tee, and actually had never noticed that it was different, lol!
I like your idea of removing those valves. I have gotten to the point where opening and closing valves is mostly muscle memory, but I have definitely forgotten to open the MT return a couple times and wondered why I wasn't getting flow![]()
