Typically, with a sand filter, if you have dirt and debris returning into your pool via the jets, this is usually a sign of broken lateral's which will need to be replaced.

i have the same problem. if i manually vacuum using the rinse setting on my sand filter i get a slow release of dirt coming back through the jets. i have already replaced the gasket in my 6 way vavle that was destroyed as well. at first im thinking that the sand in the filter needs to be changed because i dont know how old it is. now if your saying laterals could be damaged i could check those as well when replacing the sand. cant keep the darn dirt out of the pool!!!!! ahhhhhh : )

mr.t,
It could be something as simple as the filter needing to be backwashed. When the filter is totally clogged, it can "push" through dirt it would otherwise capture.


hopper,

The "rinse" position is not for vacuuming. You should vacuum in the "filter" position. (in special conditions, you could use the "waste" position but not normally)

"Rinse" is to resettle the sand after you have backwashed thoroughly and should be used only for that purpose....usually about 30-60 seconds..

Fine dust will go through a sand filter. It could also be due to channeling in the sand, which is caused by a pump that is too big for the filter.

What pump and filter do you have?

I have problems keeping my pool clear and often clouds over when vacing. I suspect my pump may be too big at 1,2 w. My pool is about 50c/mtrs (55,000ltrs) The lift is about 15mtrs including at actual lift of 2.5 mtrs to the solar heating on a roof.

Any comment would be usuful

Pump size will not cause sand channeling. This is caused by "spent"/old sand that needs to be replaced!

I am having the same issue. We purchased a new system of laterals, we changed our sand, we have backwashed, we have tried everything and continue to have the same problem. My husband is ready to tear the pool down due to the hassle it is creating. I am driving myself crazy trying to figure it out and we have had to reschedule someone coming out to our house 2x's due to the weather. I don't want to wait another week before they can come. I want it fixed! Please any help would be appreciated!

I have the same problem. Very fine dust and dirt may be too small even for the sand to filter out. So, it runs right past the sand and back into the pool. My thought was, how can I filter out this fine stuff when I vacuum, so I did this. I bought and tried two different things. First, I bought a bag of fish tank filter material. its very fine, soft and comes in a sheet. you can cut it to size and place inside your filter baskets to catch small stuff that would normally go right thru the basktets!
Next, because this was still letting in the cloudy stuff that collects at bottom of pool, I bought the paper cylinder cartridges that are really meant for pool filters that use a cartridge. I had to cut them up to fit into my filter baskets. But so far, when vacuuming, they are filtering out much more of the fine dirt particles that usually bypass the sand filter. its not 100%, but its better than it was. Just watch your pressure guage and clean/remove these added filters as needed - they get pretty gunked up and will decrease the pump pressure. Other than that, i have new sand thats only a few seasons old. But, when I changed the sand, I noticed that the "umbrella" rig inside the sand filter that has the jets was cracked toward the top. I didn't have the time or $200 to replace it so I just put it back since I wasn't really having a problem back then. It was only after replacing the sand that I noticed this problem, where I vacuum and watch the cloudy dirt come right back into the pool - how aggravating!
