Tips for Bumping and Backwashing a DE Filter

Backwashing a DE filter system in your swimming pool varies greatly from the process for backwashing a sand filter. Don’t risk damage to the filter or contamination of your swimming pool water by attempting to clean a DE Filter without first familiarizing yourself with the process.  read more…

The goal of backwashing a DE Filter is to clear it of all debris and increase the efficiency. This requires cleaning the internal elements and lowering the pressure. In doing so, you will be able to cut down on the costs associated with maintaining your swimming pool, and ensure that the water is kept safe for your family and friends to swim in.

Most DE Filters will have a handle on the top. This handle is referred to as a bumper handle and is designed specifically to allow you to relieve pressure in the filtration system without the burden of backwashing. This allows you to extend the time normally needed between backwashing, giving you more time to spend enjoying the pool and less time maintaining it.

Bumping the DE Filter System

Before getting started, make sure that the motor and skimmer baskets are clear of all debris. This maximizes water flow to help hasten the backwashing process. You will then pump the handle between 5 and 7 times, pushing down slowly but pulling up with a rapid motion. You should then be able to restart the motor and see a restoration in the pressure, if not, then it is time to backwash your DE Filter.

Backwashing the DE Filter System

Begin the same way as you would with bumping, by clearing out all debris and shutting off the motor. You will than need to connect a backwash hose to the bottom of the tank in the port that is labeled “backwash”. If you do not also see the shut off valve, then remove the plug that closes the port and install a shut off valve in its place. Disconnect the filter hoses during this step to avoid losing any water while installing the shut off valve.

Now follow the same directions for bumping as outlined above. When you have completed this open the shut off valve and allow the water to leave the filter, bumping the handle a few more times in the process. Make note of the color of the water, once the cloudy appearance has been replaced with a clear one, run the filter for a couple of minutes before turning off the pump.

With the filter running, you can add the recommended amount of DE directly to the skimmer. Follow the manufacturer directions carefully during this step to avoid adding too much or too little.

Once you have the hand of backwashing your DE Filter, the steps needed will seem very easy. This type of filtration system is specifically designed to make pool maintenance simple, and to save you money and time.
