I have had a problem all summer with dirty water returning to the pool after backwashing and rinsing. I bought a new pump and filter this year. I do not have his issue if I use the waste option. Specifically, when I turn on the filter, I will get five seconds of clean water and then about twenty seconds of dirty water before it clears up. I do check the glass bottle to ensure that the water is clear before I return to the filter position. I just closed my pool for the winter and emptied the filter completely, checking the parts of the filter in case something was broken, but all was good. When draining the filter it was obvious that the sand was dirty as the water draining out was dirty. Thoughts?
