Knowing how to backwash a pool filter is a major factor in keeping your pool crisp, clean, and ready to go. The filter’s primary job is, well, filtering…and this job can’t be done properly unless it is unclogged.
Having a dirty filter is almost always a prime suspect when we are facing pool issues…whether it’s weak water flow, a dirty or cloudy pool, or certain equipment not functioning properly.
Let’s learn how to maintain our filter so that we can keep that nice, crystal-clear water we all desire.
As your pool filter is doing its’ job, it becomes dirty as various contaminants start to get stuck to the media. As these contaminants start to build up on the cartridges, or grids (if you have a DE filter), it gets harder and harder for the water to circulate.
A blockage of sorts starts to occur…much like how it is harder for blood to pass through our arteries to our hearts as plaque builds. In addition, the pressure in the system starts to increase (much like higher blood pressure).
We don’t want our filters to have a heart attack, and backwashing the filter really helps get rid of all that excess junk. It can help relieve the higher pressure in the filter, and get the water circulating properly again. As backwashing becomes less effective, a full-on filter cleaning will have to be completed.
You can find out how to embark on the journey of a deeper filter cleaning here: deep clean your filter.
Lastly, backwashing a pool is of vital importance because it helps prolong the life of your filter. Replacing cartridges or DE filter grids can be very expensive. The cleaner you keep your cartridges/grids by regularly backwashing, the more life you will get out of your filter media.
You should backwash your filter once the PSI on the pressure gauge raises to too high of a level. How high is too high? Well, usually when your baseline PSI level raises to about 10 PSI or more.
In order to know what your baseline PSI is for your filter – be sure to check your pressure gauge after a good filter cleaning, or when your filter is first hooked up.
If you’re unsure of what your baseline level was, or if your pressure gauge is broken, you can default to once or twice a week during the pool season.
If you notice your returns pushing a little weak, or your skimmer suction doesn’t seem great – give backwashing a go after emptying all your baskets. Don’t worry because as you will soon see, backwashing is a fairly simple process!
Most of your filtering issues can be solved by following the above guide. It only takes a few minutes and can really make a world of a difference for your pool and your pool system.
If you still have low flow after backwashing your pool filter, then you will most likely have to get down and dirty and give the filter a thorough cleaning.
