Thank you!! I have literally been searching for a video like this for the past few months and the others never really showed what to do.so thank you !!
Interesting, as on my valve, the backwash operation is done with that valve pushed down and locked. Regular filter mode is with that valve up, and locked. Why is there a difference? Also, yours is installed backwards to what mine is. The open slide slot on mine faces the sand filter, not away from it.
