Hi all,

I have a swimming pool with a diatomaceous earth filter. I have heard that
you have to clean the filters twice a year, but I find myself cleaning it
about 4 - 5 times a year. The symptoms that make me clean it: The Kreepy
Krawly stops moving, and the pressure on the filter is about 10 lbs. more
than when it is freshly cleaned.


Sounds just about right.

Believe me, it's a chore. Does anyone here have experience with these, and
is there some maintenance that I am not doing that is making my filter gunk
up more than usual? I try to keep the pool clean, although sometimes it
gets a little green in the winter months before I take care of it.


I see in your later post you apparently don't have a back wash valve.
I've never seen a filter set up without one. That's why it's such a
pain in the arse for you to clean it. I only take mine apart for a
thorough cleaning once every one or two years, the rest of the time I
just backwash. Eventually the DE will build up inside and backwashing
won't get it out and you do have to take them apart to clean them. If
you don't they will not last the 2 months between cleanings but will
only go 2 or 3 weeks.


Thanks for your advice,

Ryan
