@Syd Here is a thread with pictures. The "sweet spot" seems to be around 1.5 and 2. If the pump is set too high, it might gurgle and bubble. Too low, and the glycol doesn't circulate.

The pumps are circled in red on this illustration here, which is similar to our TaB400 setup:

I found it easier in my 2019 400 to see the little adjustment arrow on the main circulation pump from the outside access door. For the Flo pump I could see it better by lifting the panel at the head of the bed and looking down. maybe just the way my pump controls were oriented. And the scale for changes on the pump are not exact; mine has a small red arrow that you turn to about where you want it. I found after my flush with no air in the system that having the pump high (at 5) led to the reservoir tank pulsing with the fluid and that is what I could hear most. I turned mine to around 1-2 and I could see movement in the reservoir, but no noise or fluid churning, just a low hum from the system. I set my main and Flo to approximately the same spot.2019 T@B400 Boondock Lite "Todd"2016 Toyota Tundra 5.7 Crew Cab

Thank you everyone for your help. On our first trip of the summer and we have more hot water than we know what to do with. I think it was the calibration of the pumps that finally did it.Hopper - 2019 T@B 400
