How frequently should the sand be changed on the filter system?

If you are backwashing more than you care to,or your filter pressue is high, or you put your hand against the outlet where the clean water is returning back to the pool and your hand does not get pushed away any of these reasons would be a reason to change the sand, depending on the size of the filter some filters need to be changed once a season every other season or not for years, bottom line you should only be backwashing after vacumning the pool. if your water in your pool is clean or clear I would say the sand is ok.
