I am confused as to whether or not sand needs to be changed in a 7 year old Hayward Pro Series 310t. Some websites say sand needs to be changed every 3-5 years, while others say sand will not ever wear out. We've had some issues this year with our water getting cloudy. It's been a rainy, humid summer in the northeast, so I'm not sure if that's par for the course, or if it's my sand. What are everyone's thoughts about sand replacement?
Finally, I saw a video that showed pulling out the screen at the bottom of the drain to let the sand and water out that way by flushing with hose. Anyone ever hear of this? Thanks so much!
