WHY AM I GETTING DE BACK IN THE POOL?

by KATHY
(POUGHKEEPSIE, NY USA)

I HAVE OWNED MY 18 FEET ROUND ABOVE GROUND POOL FOR ONLY TWO YEARS. EACH YEAR I HAVE HAD TROUBLE WITH DE COMING BACK INTO THE POOL AND THIS YEAR THE FORCE OF THE WATER SEEMS HIGH COMING FROM THE RETURN.


I PUT APPROX. 4 CANS OF DE IN THE SKIMMER AND HAVE THROUGHLY CLEAN THE FILTER AFTER EACH SEASON SO AS NOT TO HAVE ANY CLUMPS OF DE. THE PRESSURE IS ABOUT 10 AND THE POOL WATER IS CLEAR. IS THERE ANY DAMAGE WITH THE DE COMING BACK INTO THE POOL? IS 4 CANS TOO MUCH?

I ALSO HAVE A PROLINE FILTER, NOT A HAYWARD. IT HAS BEEN EXTREMELY DIFFICULT TO CLOSE THE FILTER (LINE THE TOP PART WITH THE BOTTOM PART). IT HAS TAKEN SEVERAL MEN AN HOUR TO CLOSE IT WITHOUT WATER COMING OUT. THERE IS AN O-RING IN PLACE? ANY SUGGESTIONS? I AM AFRAID IF I OPEN THE FILTER, I WILL NOT BE ABLE TO GET IT CLOSED AGAIN.




Thanks for the question Kathy

I know it's frustrating to have DE coming back into the pool. You're not alone the quest to have the DE stay in the filter. Here are some link to questions I've answered about this very problem:

DE Filter Problem..DE Coming Back Into The Pool..

How Much DE Powder Do I Need To Recharge Filter?

Purex Filter With Unicel DE Grids..DE Keeps Coming Back Into The Pool..

Some other reasons are:

Torn filter grids - Remember to check the end of the grid.

Broken manifold

Broken and/or missing air relief strainer

The above links have alot of information. Things to look for and check out. Although the DE manufacturer might be different, it's all the same problem. I believe the Pro Line DE pool filter series does have an O-ring. There's the O-Ring Hose Assembly and a Drain / Inspection fittings.

Many times when the two halves are put together there might be a spot where the O-ring or gasket in being pinched or mashed down. This will cause the top and bottom to not be sealed correctly. Be sure the O-ring has no tears or rips, and it needs to be clean. It also needs to be the right size. Try not to force anything. Many times this is where the pinch takes place.

Be sure you're using a real DE scoop and not a coffee can to measure your DE. I go into detail about that in the links above and this one:

Hope this helps. Have a fun and safe Summer and good luck with your filter.

DE Washes Back Into The Pool
by: Kenneth

I have a DE earth filter for the last 5 years. I have had no problems. This year on start up I did the usual but the powder just back washes back into the pool. I backwashed it three times and tried again.

As soon as I add any and wait the powder just comes out of the jets even with just a pound in a mix of water.
