Thank you TFP. At times, I got lazy a bit but my pool is in its best shape ever. I would like to make it better with your help.
I've had very fine sediments that I could not get rid of using polaris pressure side vacuum. I tried a finer net but still same thing. I get fine dust sediments on my steps. When I brush my pool, these particles make my pool cloudy.
So got a hose and a manual vacuum head and started to vacuum. I can see that fine dust are gone as my vacuum head passes then I realize that my filter is not working. I had no idea it wasn't working. I saw a dust cloud forming in front of one of return lines as I was vacuuming.
I read somewhere that air bubbles in the system will reduce filter performance. So I decided to take a closer look.
When pump is running, I can use the air release nob on top of my filter to release air for 20 seconds before water comes out. I can close it and within a minute, I can do this again and again releasing air for 20 seconds at a time.
Air is entering and I needed to figure out. At first, I thought the problem was water fall (its value) but then when I shut that off, I still had problem. Next I stop the pump and saw air entering thru rubber seal on top of the pump.
I am going to fix this by changing the rubber o-ring. Please let me know if I need to do something else. Yeah! I figured out on my own. Well, the truth is that I read somewhere in the forum that I should check the pump seal. Thanks TFP again.
Anyway, I was doing so good that I decide to clean the filter as well. I don't know when the filter was last cleaned so it's probably a good idea.
I took the bolt off the filter but I can't get the top to come off. Are these really tight? I don't want to force it especially when it looks like the filter is not anchored to the ground.
Here is a picture of the bolt I took off but the thing that wraps around the filter won't move at all.
And also, this is the picture of bottom of filter. What is this for? Looks to be a drainage of some kind.
Thanks for your help.
