Hello and thanks for letting me join!!
While searching google for answers I found this forum ... so glad I did. My above ground has served the family well for 4 yrs trouble free. This year I'm experiencing my first problem. In the filter mode I have very little return flow ..I can almost stop the pressure coming thru the return line with my hand ... in recirculate I have very strong flow ... waste mode very strong.
The only thing different this year is I took out the old sand, cleaned everything ... put in new sand. Perhaps I got something put back together inside the filter??
