There’s some bad information going around right now about how much water is wasted with DE filter systems through backwashing.It is simply not true. All you need to do is stop backwashing and manually clean your filter instead, according to your filter manufacturer’s instructions. It’s easy to do and you can still continue to use the best filter aid for swim pools – DE.
Backwashing is not a necessity and while every filter has a multi valve back flush option it doesn’t replace regular manual cleaning, just like you do pre and post a swim season. It’s the water saving right thing to do to take your filter apart, wash everything out and reassemble it with a new charge of DE. By doing this, you’ll save an average of 10,000 gallons of water every year!
Think about it. You get all the benefits of DE filter aid, the ultimate in water clarification for a pool or spa that truly sparkles and the most efficient dirt-removing filter media available for removing particles down to two microns. A properly balanced pool gives you the clarity and quality you want, reducing the use of chemicals and disinfectants. And you save a lot of water!
