Hey guys. So in June I’ll be going on vacation for 7 days and I know for a fact my current ATO doesn’t hold enough water to last the full week. I was going to try and set up a backup reservoir to use when my main reservoir runs dry. I have a few different float switches and a Apex breakout box to use for this process but I’m not quite sure how to go about coding it. I’ll more than likely use an apex pmup as the backup reservoir pump and a couple magnetic float switches
