I did do a search before i decided to post. I have been getting a slow, constant sand acumulation under my return jet. Probably a cup or so every 3-4 days. I found a few threads that point to laterals in my filter. The guy at the pool store confirmed that either the laterals were damaged or the sand was too old. He said that it breaks down over time like river rocks and can eventually get so fine that it can blow past the laterals.
This is my first season at this house and running the pool in general so i left the pool store with 200 lbs of sand and 2 laterals in case i found any damage. Well i diddnt. The filter is now cleaned out and all laterals removed for close inspection. The internal plumbing does not seem to have any cracks or damage.
Is the sand breakdown story a line of BS? It was enough effort taking everything apart that i thought id fish for a few opinions before filling with new sand and hoping for the best.
A few pics just because plain text boring.
