Question about Hayward EC75 HAYWARD PERFLEX FILTER SYSTEM W/1HP PUMP
I have cleaned it with acid for 48 hours, backwashed it all the fingers in it seems good. When I bump it it will put out a lot of pressure but then it starts slowing down until nothing the guage stays at 20 all the time. I can't see any leaks, don't know what else to do.
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
