This is my first FULL season with the new 30' AG. I am seeing some sand along the seams quite often.Vacuumed yest. and wa la...today....more sand. Probably only a 1/2 a cup full. Not much, but annoying. A friend of mine told me not to back wash as often, as it makes the sand "more sticky". This didn't sound too intelligent, AND I don't back wash every single week. My pool doesn't have many people in it often, and at that not many kids. I backwash about once every 3 weeks. I know I know....but it's looked good since day 1.

Anyway, I don't assume I have a cracked lateral, and probably have a lateral head with some "space". The filter was already assembled when they installed, so I guess I have to wait till I close the pool in order to "check this". Sounds like a good plan, but I guess I can deal with the sand till mid sept when we close.......

I just can't imagine how to do all that with the pool still open? Plus, I would rather try and wait and just kill two birds w/ one stone and change the sand next season. I know that with Chlorine, they say every 3-5 years, but whats $30 or so to ensure sparkling water w/ fresh sand eh?

Anyway.....keep this post going. Very educational....and with all my jibberish, can someone post me back?
