I’m installing an Apex Duo to perform automatic water changes. The water will drain from the sump into a basement drain and refill from saltwater mixing bins also in the basement. The Duo will be installed in the basement as well.
My question is, how do a prevent a siphon from the line in the sump draining the old saltwater?
