Pool Filter Repair and Installations

Pool Filter Repair and Installation

Our technicians clean, repair and replace all makes of Pool Filters. Two filter cleanings a year are recommended to help keep a pool cartridge filter or DE filter working optimally, which in turn keeps the pool water clean, clear and health. If you need a Pool Filter Cleaned, Repaired or Replaced, give us a call at 832-870-3669 for quick service and accurate work.

The D.E. filter can stop particles down to 3 – 5 microns. DE filters use a pressure gauge to indicate a need for backwashing, which is when the gauge reads 8 – 10 lbs. higher than when it was freshly cleaned. After backwashing a D.E. filter, fresh D.E. filter powder is added back to the filter. Two filter cleanings a year are necessary to keep the D.E. filter grids clean.

Diatomaceous Earth Powder is what does the actual filtering in a D.E. filter. This is a widely available, inexpensive powder which is made up of microscopic skeletons of Diatoms, a very old, sub aquatic creature. This is what catches the dirt IN your filter. The powder coats the grids, which are covered with a nylon type of fabric. The water continues to pass through, first through the powder and fabric covered grid. As the water passes through it leaves the dirt, trapped in the D.E. powder.

The D.E. powder is what filters your pool water in a D.E. filter. Do not operate your pump without having the D.E. powder coating the grids, or you will see your pressure rise very quickly, and if left in this manner the grids could become damaged. As the pressure gauge on a D.E. filter increases, flow rate decreases. Eventually the flow rate will allow the water quality to suffer. You will need to backwash the filter to remove the D.E. that is clogged up with the dirt.

After backwashing thoroughly, add new D.E. powder to the filter through the skimmer. If using biguanides (Soft Swim or Baquacil) you will need twice annual, very thorough cleaning to prevent it from gumming up. All D.E. filters should have this done at least once per year. Thorough cleaning is accomplished by turning the pump off and draining the filter. Remove the tank top half and remove the grid assembly. Hose the grid assembly thoroughly. Soak the grids in a trash can filled with water and a filter cleaner product. Rinse thoroughly before reinstalling grids into tank.

While cleaning the DE grids, it’s good to inspect them for tears and holes. Holes in your DE grids larger than 1/2 inch will need to be sewn or replaced. Inspect also for mis aligned grids, and correct, and check that the through bolts are tightly secured so that the assembly is drawn close, and the grids are snug into the top manifold and the bottom spreader plate.
