How Much Water in Brine Tank
There is exactly one exception: when you’re adding new salt. After you pour in fresh pellets, the softener will sometimes add a little extra water to pre-dissolve them. This is fine, and it’ll go back to normal in a day or two.
How much water should be in my brine tank: real numbers
But if you see the water rising higher than the salt—like you’re trying to grow an aquatic salt forest—call a plumber. Or just sigh deeply and reset the timer. Your choice.
Also, please don’t try to drain the tank yourself with a garden hose unless you enjoy wet socks. I’m not judging, but I’ve seen the results.
