The brine tank is where the 150 lbs of dry salt is added and gets used up slowly. The Brinewell is the 4" tube with a cap that sits inside the larger brine tank. Did you mean the brinewell? There are no salt bridges if that is what you meant. I can't see to the bottom of either the brinewell or the brine tank. Can you clareify?
And just to clarify my previous post... I have 5" of water sitting on top of the brine tank.
This is where I add the salt and is normally all dry. And also, because I am seeing water by the electronics and valve assembly way on top ( just under the cover), I am thinking this is where the water is leaking down into the brine tank ( which normally should be dry). I can't see exactly where that wetness in the valve assembly is coming from but likely from an O Ring. I will have investigate further.
