For those of you with the blue-tubes and the water cooler:
How can you tell if the water is circulating properly - short of pulling the input side out of the cooler and seeing if you get splashed? Is there any indicator built into the system?
With the blue hoses, I cannot see what’s going on in there…
I have clear hoses & there is usually bubbles at the top of the loop above the spindle. I watch that they move when I turn it on. Splice in a section of clear hose? Add a sediment trap?
