The PB says he normally plumbs the two returns (plus an eyeball on the steps) together, one return on opposite corners of the ends. I think I would rather have individual lines for each return with ball valves for each. I also want them to add a third return low on the sidewall to aim down into the 8' hopper. They also normally run 1.5 inch lines and I'm having them use 2" instead.
What do you think is the best option?
