I'm building a new sump and wanted to put a bracket on the side for holding probes. Since I don't have any yet, I need someone to tell me what size hole I should drill in the bracket for a future probe(s).
Thanks

Most standard probes are 12mm diameter.

Thanks Jim. So I should drill a hole slightly larger than 12mm or a 12mm hole would work? Should the bracket be just above the water line?
