Sand Filter Wash and Cleaning:
- Shut off the pump and close the valves.
- Take off the valve head.
- Unscrew the drain plug.
- Drain the water until the media is visible. ( This may take a while.)
- Examine the surface of the media. Take out clumps of debris and check for level media. Dips in the media or media tilted to one side may indicate a broken lateral. If laterals are broken, have them repaired by a pool professional.
- Replace the drain plug.
- If the filter is a sand filter with sand, pour 2 gallons of liquid muriatic acid, or enough to cover the filter media, into the filter.
- If the filter is a sand filter with GlassPack® Filter Media, pour 2 gallons of regular liquid household bleach into the filter, covering the media.
- Let the filter to soak overnight (about 12 hours).
- Backwash the filter to “waste”.
DE Filter Wash and Cleaning
- Have the DE filter broken down for cleaning and checked for broken grids.
- Remove the grids.
- Soak the grids in a 2 parts water to 1 part liquid muriatic acid solution for 12 hours. (Soaking grids is critical twice yearly.)
- Reassemble the grids.
- Add DE powder.
How and When to Clean the Electrodes
The electrodes in a pool system need to be cleaned 2 times per year. Also clean them if there is visible build-up on the electrodes. DO NOT TAKE THE ELECTRODES OUT OF THE CHAMBER TO CLEAN THEM. Remove the entire chamber and place it in an acid and water solution, 5 parts water and one part acid.
- Make sure the pump and filter are off and the valves are closed.
- Slip the wires off of the metal tabs on the outside of the chamber and unscrew the chamber from the return line. If the unions don’t loosen by hand, try a strap wrench. Be careful not to crack the chamber.
- In a 5 gallon bucket, mix a solution of 5 parts water to 1 part acid. Pour the water in first and then the acid.
- Place the entire electrode chamber in the solution for 10-15 minutes. Allow the solution to do the work.
- If the chamber isn’t clean after 10-15 minutes, let the chamber soak longer, but not longer than about 1 hour.
- Do not scrub or scrap the electrodes. Using tools to scrape the electrodes will damage them.
- Remove the chamber from the solution and rinse in fresh water.
- Replace the chamber inline and hand tighten the unions.
- Replace the wires on the chamber. Red and green wires go to the copper electrodes and the black and white wires go to the titanium electrodes.
