I searched and searched, and couldn't find any topics dedicated to how to deep clean your sand filter. Though I found some off-hand discussions in other threads.
It seems I skipped a step somewhere... maybe someone can help me out.
I unscrewed the top of my sand filter. I placed in my water hose and began the 'deep cleaning'. All well and good so far.
But the dirty water never over-flowed from the top of the sand filter ------- because it was going back into my pool thru the returns!! I could hear the water moving thru pipes, so I ran to the pool and confirmed water coming out of the returns. Yikes. Now instead of my sparkling pool, its just a tad bit cloudy.
Anyway --- where did I skip a step? How do I stop the flow of water to the pool? Even if I put it in 'backwash' mode, the water still dribbles down the backwash tube instead of really coming out of the top of the filter. Am I missing something that's painfully obvious, and I'll be embarrassed for life for missing?
