Hi All -
I recently replaced the sand in my Jacuzzi Laser 250L sand filter. When I did it, I checked the laterals and the stand pipe, and they all seemed fine (although I will admit, I don't really know what I am looking for other than visible cracks). Since putting it back together, there is sand coming into the pool through the returns. There is not a big pile of sand under the return, as I have read will happen when a lateral breaks. But there is a steady stream of sand blowing in when I run the filter.
The most concerning part to me is that this happens even when I set the filter to Whirlpool (which I think is the Jacuzzi equivalent of Re-Circulate). My understanding is that this setting would not touch the sand at all, so I am concerned that the problem is bigger than just a cracked lateral or stand pipe. I could replace the whole valve, but I would hate to do that and then find out that it wasn't the problem. And I could obviously remove the sand and check all the laterals again. But, I thought I would post here before I tried anything else and see if you guys had any ideas.
Edit: I don't know if this is an important detail or not, but I used Zeolite instead of sand.
Thanks in advance,
