I have a 1.5 cu ft twin tank softener and I’m getting a significant pressure drop at high flow rates. I know that there is no gravel. I’m pretty sure that’s what’s causing this. So, I’m thinking, if I were to add the gravel I need without emptying the resin out of the tanks, it would settle to the bottom on its own when I backwash. Sound reasonable? Or am I’m just going to create a bigger mess than if I empty out the resin first?
