Just in case.....what are the signs and symptoms that your pump and/or sand filter is NOT working correctly? Possible channeling of sand - symptoms?
The outflow is good...motor on pump squeals a tad SOMETIMES, but otherwise sounds normal. However, JUST IN CASE....what is the symptom of sand filter channeling????? Our sand is now on it's fourth season ( previous thought 3 seasons). I have read that alot of you do not change your sand. My pressure is always good, at 10.
Thanks in advance!
