Question about Hayward EC75 HAYWARD PERFLEX FILTER SYSTEM W/1HP PUMP

1 Answer

Hayward Perflex EC-75. The DE is gumming up after about 1 week all up in the fingers. Keep taking the filter apart and washing it down then replace the DE but only getting one week out of the new DE? About 8 weeks ago I did do a rejuvenate with acid...not sure what i did can't find the directions I wrote down. That seemed to help for a short time but not a sure fix. Can anyone help please?

I maintain three commercial pools ... one a hot tub. We replaced the DE with sand filters this spring. The last year of DE - even with insisting the patrons shower first, we only got one week out of the DE ... and we were dumping the water also. Suntan oil, body oils ... it was a mess. The water was sparlking for 6 of the 7 days ... The only way to keep it that way was dump the water and change the DE.

Maybe your filter is not big enough. Had you given the gallons or the size of your pool, I would have calculated the filter area for you. If you can post it and if FixYa, notifies me, I would be glad to do the calculation.

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

My hayward de filter will not filter over 1 hour


How much DE are you putting in it??? If it is a EC40 then no more than 4 small coffee cans of DE.
If it is an EC65, then no more than 6 - small coffee cans of DE. ( you can even shy back by a 1/2 of can of DE, without any problems.
Is the pool green??? If so, the filter will continue to plug up until clean.
Keep your Chlorine abit on the high side...DE filters run best with a chl reading of 3.0
