Should air check valve in Autotrol 255 be full of water or air?
Have a newly-installed softener with an Autotrol 255 valve. Before I call the installer back--should the air check valve be full of water or air? Would there be a good reason that there is no check ball in the air check valve? Could this be the reason that the brine tank refills with water (at least half full or more) after the system regenerates? The water stays well above the salt level.
Got the answer to brine tank full.
Okay Speedbump, thanks for the input. Was able to contact dealer wthout having them come out (and me waiting around for them); they say the newer units have the check valve built into the brine tank, but they still use the older 255 valve, just without the check ball. This also results in the sight glass in the check valve remaining full of water.
The Autotrol 255 valve follows a different sequence of actions than the old GE I had, and one result is that they leave a considerable amount of water in the brine tank so that the salt is maximally dissolved when the brine cycle is started.
Nice to have a dealer who has email contact and follows up on it. Will wonders never cease!
