DE Filter issues.....

[waste]

Hey Fog - if youy haven't already check out my post in this thread for some help with owning a DE filter.

If you've got to clear a swamp, you might try putting a Hayward SP 1091-Z-7 (backwash adapter) in the drain hole and connect a hose to it so you can ~ 'vacuum to waste'. This would bypass most of the filter fingers and might be easier than all the bumping and dumping you are currently doing (* however, it's gonna cost you a lot of gallons of water).

Keep us informed as to your progress, we're rooting for you!

Hi Waste,

I have a backwash line connected to my filter, but when i backwash it does dump out my DE. I broke down the unit yesterday and gave it a soak in dishwashing detergent and then muriatic acid. I've never seen the fingers this clean!

Now my starting pressure is 5.......the lowest i could ever get it before cleaning was 12. I noticed that three of my "fingers" lost their fabric covering and were just exposed plastic....so I've ordered 10 new fingers and a new bottom plate (which had some cracks near the main shaft in the middle). I'll be installing them this weekend.

I put in 3 gallons of 12.5% chlorine yesterday and ran the filter all night. This morning my pressure was up to 20 but after a bump, it went back down to 5. Also, the pump didnt seem to lose prime even though the pressure went up so high.....didnt know a good cleaning would affect that.

I'm going to keep on shocking and filtering and then vacuum to waste when I can see the bottom. Hopefully it will be clean soon.

FYI, i changed out all my bad "fingers"....over 20 of them. I also changed out the diaphram gasket on the DE filter. Over the next 48 hours my pool cleaned up to the point where I could see the bottom. From there I scooped out as many leaves and pine needles as i could and vacuumed up the rest.

Water is crystal clear now and my DE filter pressure is holding steady at 10psi. Thanks everyone!
