Ok...hope someone can assist. I keep my pump running on low speed 24/7. When I put the pump on high speed, I notice water dripping from the backwash outlet - quite a bit of it. When I place the motor on high speed, the leak increases. Now, I'm not sure if this is my imagination or not, but since I noticed this leak, it seems like I always have the need to vacuum the pool because of what "appears" to be sand. on the bottom of the pool. The gathering of this residue on the bottom of the pool seems to increase with the motor in high speed. Is it possible for the filter to send sand back INTO the pool? Anyone know the reason of the leak and am I crazy about sand coming back into the pool? Any help would be greatly appreciated.
