You can maintain a D. E. filter with an annual or twice yearly breakdown cleaning and inspection. Replace worn or damaged grids and tank gasket, lube the back wash valve, recharge with correct amount of D. E. If you have a back wash valve that sits under the tank then you should consider a pool service tech with knowledge of that specific filter. Because you need a couple of the correct tools to facilitate removal of the tank lid and the rotor valve assemble. This type of filter is known by several names.. . .Purex, C.H.D., Pentair to name a few of which there may be more than one model.

How does a DE filter work on a pool?
Simply put, Diatomaceous Earth (DE) are the bones of tiny little animals that lived millions and millions of years ago, diatoms. This DE is used to coat the "grids" inside the DE filter which captures and filters particles as small as 5 microns. When the filter pressure rises, the swimming pool DE filter is backwashed in the same manner as a sand filter. A slurry of DE is put into the skimmer to "recharge" or "re-coat" the grids of these swimming pool DE filters. This type of filter is effective and efficient but a little more expensive to maintain. Some call it the "water polisher" of pool filters.

Is a cartridge filter better than a DE Filter?
A DE filter will filter finer particles. It also depends on the application. Some cities are not allowing DE filters to be back washed into their sewer systems within city limits. (Calif) k
What are the pros and cons and differences between sand and D. E. pool filters?
Gayle- There are basicly 3 types of filters. Sand, Cartridge, and D.E. filter. Differences being numerous, but in a nut shell is the ease of maintence and care and the size micron of particle they will filter out of the water. With that said sand is the easist to maintain regularly but, cart., and DE filters filter out smaller particles. DE filter out the smallest particle but, with the most difficult to maintain and repair etc. Hope this all helps, Mystic Waters Inc. GA There's a relatively new filter medium available called zeolite, which is a volcanic sand rather than the usual silica sand. Because each grain of zeolite has one hundred times the surface area of a grain of sand, zeolite used in a sand filter filters almost as effectively as a D.E. filter while being much easier to maintain. I'd absolutely recommend that you look into zeolite before buying a D.E. filter.
Why is your filter full of de on outer filter grids?
Because it filters from the outside in. The DE is supposed to coat the outside. Hatawa
Why would the DE powder go straight through the filter and into the pool with an old Hayward DE filter ReGenX system?
Something is allowing the DE to pass through the filter - probably a hole in one of the filter pads or a damaged manifold. You can take out the filter pads and visually check them. A hole will be fairly obvious.

How do you start up a hayward ec-65 DE filter?
Turn on the pump and put in some DE. Or clean it with filter cleaner and re-assemble then turn ont he pump and add DE.
Why are you using bleeder resistor in LC filter?
In LC filter , Bleeder resistance is connected in Parallel with the load to maintain the minimum current through the choke and so the performance of the Filter improves.
Why would a DE pool filter pump the DE back into the pool via the water jets as soon as DE is put into the skimmers instead of adhering to the filter?
Check the grid and manifolds for holes or cracks.
