Diatomaceous earth is the fossilized exoskeletal remains of tiny diatoms. When the filter pressure rises, the filter is backwashed like a sand filter, It then has to be "recharged" with more DE powder. Normally it is poured in a slurry into the skimmer which then coats the filter grids.
If your filter is repaired then you can just vacuum the pool.
You pour it slowly into the skimmers and it stays in the filter
Diatomaceous earth is a great liquid filter.
Of course it can, it is one of the best oil filters available. Do not use the oil for anything other than fuel in your bio-diesel vehicle. After you filter the oil you can use the diatomaceous earth in your mulch pile, it will help in the breakdown of the fibrous vegetation.
The maintenance required light just means there is regular scheduled maintenance that needs to be done. Look in your owner's manual and it will tell you exactly what needs to be done. Can be just an Oil/Filter change. This applies to the Maintenance Required light and not to the Check Engine light.
There are three types of filters - Diatomaceous Earth Filters, Sand Filters, and Cartridge Filters.
This is a bad idea. Diatomaceous earth (de) will go right through a sand filter. It will end up back in the pool and then it is almost impossible to get out. Sand goes in sand filters, de goes in de filters.
I think you have a fault pool filter. The filter is filled with diatomaceous earth to trap algae and other particles. When there is a 'filter' to trap the diatomaceous earth and these other particles inside the filter until you clean it out. You probably have a leak so that the diatomaceous earth flows out of the filter together with the water that circulates trough it Correction: The filter is not "filled" with D E. There is only enough D E to lightly cover the internal grids. If one of them is torn or has a hole in it - there may be more than one bad one - you will get D E back to the pool each time the pump is turned on. Turn off the circuit breaker, releave the entrapped air from the filter, open the filter, remove as much De as possible then remove the grid assembly. Inspect all 8 filter grids for damage or tears and replace. When in doubt as to age of grids - replace. Reassemble filter, turn on the power and pump, add the correct amount of D E - see instructions on bag of D E - you should be ready for another 10 to 12 months of filter service before it has to be done all over again. This does not eliminate the need to back wash the filter as needed each month.
Yes, it is a permanent filter that requires no maintenance.
In the fuel tank. It is a permanent filter and no maintenance is required.
It means there is maintenance that needs to be performed based on the mileage on the odometer. It can be nothing more than it needs an oil/filter change but it can also mean it needs a new cam belt or some other maintenance. Your owner's manual outlines exactly what needs to be done at the mileage now on your Accord. Neglect the required maintenance at your own peril.
It has a permanent filter mounted in the fuel tank, no maintenance is required.
