DE Filter and Pump Strength

[jeffrx]

Hi guys,

I have a Hayward Perflex EC40 D.E. above ground filter. Last year I used it with no problems along with a 3/4 HP pump. This year, so far, the water stops flowing through the filter after about 1-2 hours. If I shut the pump off and use the lever to shake off the DE, then restart the pump, it flows again (for another hour or two only). The pool is still cloudy from opening and I'm waiting for my new TF-100 kit to arrive. I see no evidence of air leaks or anything.

My question is, is a 3/4 HP pump sufficient to do the job with a Hayward Perflex EC40 D.E. above ground filter, or do I need a more powerful filter to move the water through? Or, is this just due to dirty water, algae, etc?

Thanks, Jeff

The problem is the DE Curse. You have algae and it will clog a DE filter in a big big hurry because they filter so well.

If the pump worked good last year it'll work good this year. You just gotta kill the algae and filter it out.

Jeff,

I agree with Richard..

The number one reason for the problem you described is a clogged filter due to algae...

Once you get your test kit you should do a SLAM SLAM Process

Thanks,

Jim R.
