Why does my filter pressure rise very quickly, even after backwashing?
D.E. filters filter the water down to 1-3 microns, every time the water passes through the filter. Maintain a balanced clear pool and this will reduce incidents of rapid pressure rise. One possibility is that the filter grids or Flex tubes are clogged with minerals or oils. You should clean your grids once a year, or season, with a degreaser and if needed an acid bath. Minerals and oils embed themselves in the fabric of the filter and reduce the available surface area used for filtering.
If too little DE is added during pre-coat, debris and particles will embed in the fabric. Cleaning with a high-pressure hose, NOT A POWER WASHER, may be needed to remove the grids. If cleaning does not work, then replacement is the only option.
