After 3-4 weeks in use, I am getting what has to be salt deposits on my "out" float valve mechanism. (curiously, it does not appear nearly as much on the "in" valve.)
It's a thin layer (about 1/16th or less) but it interfers (drags) with the valve closing and, as a result, the water level in the LQ drains down after pump shut-off and allows air into the system....de-priming my pump.
That's a really huge issue for me as my pump is on a timer and cannot reprime as long as that valve remains open to the atmosphere. I have been lucky to catch it (twice).
Are any of you LQ owners experiencing this salt build-up on the valves?
