19" sand filter and a 1.5hp two speed pump. It's used and I need help with a few questions! 1. Use the sand already in it? 2. Take it out and clean it and check the laterals? 3. Plumb it and use as is? 4.Is the filter rebuildable? 5.Any major flaws? 6. Insights--good or bad ?? Thanks for any comments! This will replace the summer waves sfx1000 pump that my 17' pool came with!
