Wow, the message board was hot last night! I learned something new.
Thanks Ken for your note about the filter not needing backwashing. I
looked at an online ad after your post and I guess when it needs it
you bump it with the bump handle and then drain it. I did that once
by following the directions on the filter and thought I was
backwashing. Hopefully that means I don’t have to drain (f.k.a.
backwash) as often.
I ended up using two garden hoses and the pool vacumm hose to get rid
of my excess water in the pool. It didn’t take too long after all.
Now at least there is a little air gap at the top of the skimmer so
the surface residue will actually go down instead of circling the
pool endlessly.
Now finally for my question. When I drain the D.E. filter what
should I do with the water and “stuff” that comes out. I assume the
D.E. powder has some health risks if it blows around in the air, or
not? What do most people do?
I sure hope the weather starts cooperating and we have a weekend
without rain so I can really enjoy my pool!
Thanks for any info,
Sue

No sales gimic there! TRUTH! If you were to take to identical pools one
with a DE filter and the other with a sand filter during the day you might not
see the difference but at night if you turned on the pool light you would see
particles floating in the light like dust. In the DE pool it would be clear.
De will filter out a 3-5 micron size particle and sand a 20+ size micron
particle. There is also a difference in maintenance as well the DE filter is
more
work and more expensive. This is one reason sand is so popular.

George,
Not saying the water will never get clean but the water will never sparkle.
Most people backwash their sand way to much. A slightly dirty sand filter is
actually better than a clean one. There is a pressure guage on the valve.
When it gets to 8-10 psi above what it was when clean then backwash. A sand
will never be as good as a DE filter. Hayward has gotten away from the
extended cycle filters as has everyone else. The new filters have valves that
allow
backwashing.
