Commonly used to lower the water level or drain the pool level to the bottom of the skimmer. Ramunas Heidegger Pundit. What should the pool filter pressure gauge read? A pool system's pressure is generally measured at the filter's pressure gauge ; the usual range is 10 - 25 pounds per square inch PSI. This rating will be used as a benchmark for pressure tests down the line. Elna De Asuncion Teacher. How long do you backwash a pool filter?
Yeriel Avdakoff Supporter. How do I keep my pool crystal clear? So the best way to have a crystal clear pool is prevention. Keep the chemical levels within the ideal ranges.

Is pool shock the same as chlorine? The true difference amongst chlorine does not lie in the form it comes in, but rather from being either unstabilized or stabilized.
Liquid chlorine and powdered shock have the same active chemical that work to clean your pool , the difference is in the way that you use them. Cristie Henschke Beginner. What happens if you swim in a shocked pool?

When we get a lot of rain, and the water gets over the top of the skimmer, it takes about 10 minutes to get it back down to the proper level. I assume you have a sand filter, Tom, since you were told to "Rinse". The short answer won't help you understand best practice, so please bear with my attempt to educate. First of all, with a sand filter, it's better if you don't backwash too often.
The layer of debris that accumulates on top of the sand actually helps to filter out increasingly finer particles. So, as long as you have good flow going back into the pool feel in front of the return jet there is no need to backwash the filter. The pressure gauge can help out as an indicator, but your water flow is the key. Don't rely soley on a schedule ie: once each week or the pressure gauge to determine how often to backwash.
If the debris load is low it's feasible for you to go weeks or months without the need to clean the filter. Now, when you DO backwash, run the pump until the discharge water is relatively clear. Again, it's not something that can be determined with a watch. How long it takes is determined by the size of your filter, type of debris, water flow rate, etc.
Best practice is to let the sand settle back down on it's own. Two reasons: 1 Loose, churned-up sand has a greater tendency to "channel", where the water digs a hole right down the center with the sand pushed to the sides leading to poor filtration, and 2 By letting it settle on it's own, the heavier sand falls back down first, followed by progressively lighter and smaller sand, creating increasingly finer layers of sand on the top.
That way, when you do start up your filter again, the finer sand on top will give you much better filtration. When you shake it up, then set it down on the counter and let it settle on it's own, you will see how the sand stratifies while settling. You can always run the filter in "Waste" while waiting for the sand to settle if you need to lower the water level further. Then run in "Rinse" for about seconds just before going back to "Filter".
