I have a 120DT with two internal overflows - both with 2 1" bulkheads being used for a return and drain. As a precaution, I want to add a float switch to the DT in the overflow (so it's not visible) that in the event my drains aren't keeping up with my return I can turn off my return pump (via Apex).
Any reason to have a float switch in both overflows? And if so, how are they wired so that any one of them trip the switch?
Sources for mounting bracket for the switch? I like the idea of something like this - https://www.thingiverse.com/thing:3932450, but perhaps a magnet mount would be better to be able to adjust the height.
