I think my filter may be having some issues. I just purchased a new 1 hp Hayward Max-Flo pump, and matching 21" sand filter this season. I did not install it, but a very highly recommended family business did. Ever since the first backwash, I would notice sand coming out in my driveway. I read up on this, and saw that this was not out of the ordinary for a new filter, but 3 months later, I am still seeing some sand come out when backwashing.
The bigger issue is that I feel it isn't trapping dirt very effectively. I have been away from home from much of the past 3 weeks, so when I vacuumed yesterday, the pool had a fair amount of dirt. I got most of it, but the stirring of the water made the deep end pretty cloudy with dirt. Fast forward to today, and the deep end is still pretty cloudy, and there is new lines of dirt in the shallow end as well. Also, I have gone stretches of weeks without seeing a single psi increase on the filter.
I made sure to rinse thoroughly after each backwash to prevent channeling, but something doesn't seem right. Does anyone have any suggestions to troubleshoot the issue? Thanks for the help.
