Okay, here's the deal. We have a giant pool that has two Triton 2 sand filters. We started getting sand coming from the jets back into the pool.
We drained all 925 pounds of sand from the first one, replaced all the laterals (no apparent damage to those) Very carefully added the fresh sand in slowly as to not break the new laterals.
Still sand coming back.
Drained the other filter of sand. Discovered a lateral just laying on the bottom. We were excited thinking this may solve our sand problem!
So we checked to make sure that our air tube was not displaced. (which was another thing I found while googling why sand was coming back)
Please help if you have any suggestions. I'm pulling my freaking hair out with this!
