Would anyone happen to know what kind of cloth(for lack of a better
term) covers the plastic grids on a D.E. filter? All of my grids have
one or more small holes which is causing the D.E. to get into the pool.
Replacement grids are gonna cost almost $200.00. I'm hoping I can get
the material/cloth/whatever for a lot cheaper and sew up some new ones.
Thoughts, comments, suggestions ???

That's what I am thinking as well but am not sure where I would find it
or what type of weave is needed.
Ah well...looks like I will end up buying one grid each paycheck until I
get the thing replaced....
D.E. Filter grids are covered with a canvas-like material, quite sturdy. If
you have holes, any size, replace them. D.E. continually flowing through
your motor because it is circulating in the pool water can eat up the
fly-wheel - that hard plastic difuser just inside the motor housing. It
can't take it for long.
If you can only afford one grid at a time, so be it. Any grids that have
holes should be removed and if you can't replace them just yet, then get
plugs for the holes in the bottom of the filter and block them off while you
wait to replace them. Do not use cork, get the hard rubber. Home Depot
carries rubber corks.
Depending on the size of your filter, I don't think the grids are that
expensive. When I had the 18" they were about 23.00 each, the filter takes
8 now that I have the 36", the filters are about 42.00 each and I had to
replace one already because like a fool I tried to twist it out of the
filter and the connection tip snapped off.
The grids are a small price to pay vs. the damage you can cause otherwise.
After you have replaced your grids, you might want to take the time to open
the cover on your motor and inspect the difuser for any cracks or chips.
You might be surprised what you find.
if the holes are small, the DE will just fill them,
a small amount of DE will get into the pool anyway, it will circuilate
around and get trapped inthe filter eventually.
do you have a really large amount of DE making the water cloudy?
if not, don't worry about it.
Why? Very poor chemical resistance.
Why? because that's what a remember from opening up a DE filter a
couple of times a year for several years when I was a kid. Now I have
a pool guy & I don't have to do it myself. :)
The feel & look was nylon; could I swear to it? No.
Chemical resistance? how much do you need for pool water?
Chorline ppm? pH?
Free chlorine eats just about everything. Fibers have high surface area to
mass ratios and are especially susceptible to weakening if not inert. And
it is not unusual for high concentrations to wash through on occasion.
If you can afford the chemicals/electricity for a swimming pool and the
pump/filter, you can afford the proper materials/parts. There's a lot more
to it than just getting the right material; mostly in reliable application.
I'll bet if you will take a swatch of that material to a fabric shop
they can give you a good idea what kind of material it is...why don't
you call the filter company and ask them a trick question to fool them
into telling you what it is...something like..."What kinds of fabric
do you have available for screening out the most minute particles in
the water?"...and..."how many threads per inch does this fabric
contain?"...that ought to get them to spill the beans!
"The nylon mesh on the septa can be repaired, depending on how large a
hole or tear is present. Also check the points where the mesh is sewn
to the frame of the grid."
I guess my memory of work done 40 years ago is still pretty good. But
maybe they've added other mesh materials since then.
