Operating a DE filter uncharged due to mud disaster?

Happy Spring…almost.

On August 7 of this past Summer I encountered a disaster in the form of a flash flood and mud entering the pool. (Photo attached.) This was caused by construction of a new garage which caused a change in rain water flow and has since been resolved, but I digress.

The recovery method that I chose was to filter as opposed to drain, I might reconsider if this were to happen again. For two months I ran the the filter 24/7 backwashing numerous times per day and recharging with less DE each time. Eventually I stopped adding DE at all and even after the water cleared up pressure would rise at an uncomfortable rate after each backwash. I usually clean my filter annually in May after the pollen season but felt this needed to be addressed now.

Into the filter I go. The grids were coated with the larger sand particles as a more experienced user might would have predicted, hindsight! I removed the grids and hosed them down still attached as an assembly as I intend to repeat in May as usual.

The water now “looks” clear and all components appear to have survived. I do notice, not surprisingly, with the lights on at night that there are still particles suspended in the water. It doesn’t have that normal sparkle. I’m considering letting the filter run without a DE charge until my usual May post pollen cleaning. I don’t think that this will harm anything, I just don’t want to continue the frequency of backwashing and DE charging when we can’t enjoy the pool yet anyway.

Is this yet another bad idea?
 
I would replace the DE grids. The filter’s effectiveness was compromised with all the running without DE and you cannot clean the grid to then get it to work like new.
 
Thanks for your suggestion. The grides showed no signs of disfiguration, why would you jump ahead to a $1,000 remedy?

Once you run a DE filter without DE or an insufficient amount of DE, you compromise the grids. All the dirt the DE holds has now made its way into the grids and there is no way of cleaning them out correctly. It has nothin to do with the grids being disfigured.


Based on where you purchase new grids from, it's at best a $350 or less fix - nowhere near $1,000.

Because your grids are clogged and not cleanable and you report your filter is not working properly.

If you had asked before you ran then without DE we would have told you it will trash your grids and be an expensive mistake.

Just clean your grids with a good sprayer attachment, with good hose pressure. Good hose sprayer pressure should make a mess, Then reinstall those grids after inspection. If you do not have any tiny tears or punctures . Then use DE in your filter. Your shorting the time between filter cleans by days not weeks, or months by not using DE. Back washing clogged DE grids gets you know where. You can not clean DE grids by backwashing. You do not have any DE in a DE filter? Thats like saying you do not have any sand in a sand filter. It's just not going to work. This is a short cut you can not take.
 
Thank you all for the advice and input. I do wish that I had reached out earlier. This entire ordeal has been an on going headache from cleanup, landscape/drainage changes, and now equipment damage. $$$$

I have learned a lot so that is something positive that I can take from this.
