If D.E. is returning to the pool, it's usually because you have a tear in the grids or the backwash valve is not working properly and returning D.E. back to the pool.

  • Dale Cobb Aug 26, 2010

    I apologize, I need the read the model number more carefully. I'm no expert on this particular filter, my expertise is with -ground gunite pools. However, if the D.E. is returning, there has to be something out of place or damaged to let it through to the return lines.

    I am surprised that three different pool techs could not diagnose and repair it for you. I wish I could see it in person, these type of things intrigue me.

    Hopefully you get it taken care of soon, I'm sorry I could not be of more help.

After start up the de keeps coming back into the pool? Help?


If you have DE leaking in through the return lines, there are a couple of things that you should check. You probably having an opening or tear in one or more of your flex tubes. If that is the case, you will need to replace the damage tubes and the problem should be corrected. There could also be a rip or tear in the pool filters diaphragm gasket or it could be worn or loose. If you notice a problem with the diaphragm gasket, replace it. You could also have loose bolts on the tube nest plate. Try tightening these bolts.

I installed a complete hayward filter with a new multiport valve. i can see DE in my pool. what would cause this? Thanks for your help.


If these Hayward pool filters are leaking DE back into the pool, there are a couple things that you will want to check. Check for loose bolts on tube nest plates and tighten them if necessary. Make sure that you don't have a worn or loose fitting diaphragm gasket and that there are no rips and holes in it. Replace the gasket if any of these is the problem. Check for openings or tears in one or more Flex-
Tubes and replace them if necessary.

I replaced the diaphragm gasket and when I bump the filter some DE still shoots out into the pool. all the tube sheet hex screws are all tight. Paul


There are several things to check when correcting DE leaks in these pool filters. If you have already replaced the diaphragm gasket and tightened the screws, check for an opening or tear in one or more Flex-Tubes. Replace them one or all as necessary. Make sure that you have the proper amount of DE and that you don't have holes in your grids.

Here is a link to the hayward manual. Be sure to follow the pre-coating insturctions carefully.
Use only the swimming pool grades of
diatomite, such as:
CELATOM . . . . . . . . . . . Eagle-Picher Industries, Inc.
AQUA-CEL . . . . . . . . . . Johns-Manville Products Corporation
DICALITE 4200 . . . . . . . Grefco, Inc.
WITCO . . . . . . . . . . . . . Witco Corporation
The EC-50 filter uses a 5 lb. (2.3 kgs.) charge of diatomite (D.E.)

Here is a link to the hayward manual for a EC-50 I think its almost the same as the EC-45

I have the Hayward EC-40 Filter, my problem is the DE is getting into the pool. What would cause this?


Broken/torn grid, o-ring bad in the housing by the grid assembly or grids not in manifold properly. Backwash, open the filter, remove and inspect the grids (the plastic bases too).

I'm getting DE back in my pool from the 4820 filter


One of two things can cause this. Either the spider gasket is bad or there is a rip or tear in one or more of the filter grids.
P.S.
(the spider gasket is inside the valve you turn to backwash filter)

You have a leak, if DE is getting back in pool your filter is either dirty and needs to be taken apart and throughly cleaned, or you have a ripe in one of the DE cells. The pump not priming is a leak somewhere before where water enters pump. Could be a bad o-ring in a valve. Hard to tell what is is without troubleshooting, piece by piece. I would start with cleaning Filter first.

We have an an Infinity DE filter. It's blowing DE back into the pool. We've replaced the filters.


Most likely the "fingers" inside the filter housing are worn out and causing the DE to blow out the return line to the pool.
