drain-to-sump plumbing question

[laverda]

I've got it to where there is a consistent 4-5 degree difference between what my apex reads in my sump and what my little red mercury thermometer reads in my display. That's the best I can do while keeping noise tolerable.

Are you sure both thermometers read the same? I have seen more than 4 degree differences in hobby thermometers. Put them in the same are for a while to stabilize and compare them. I would be surprised if the read the same.

I'll double check that... Thanks for the suggestion.
