-I just installed my ag pool in April, and thanks to the guidance I received on this site, pretty much everything is looking ok. However, before my pentair pump there is a filter that the manual states is for hair, leaves and I guess other larger particles. They also state that it should be cleaned periodically, but not much in how to proceed. Just a quick picture in my head shows the hose from the skimmer down to this filter, mounted in front of the pump. It has a see-through lid that twists off for cleaning. I did one cleaning, turning off the pump and bleeding air before twisting the lid off. It had accumulated much debris, but the problem is all the water coming from the skimmer, before I quickly twisted the lid back on. So, I wondered if anyone else had a similar setup and how they solved it. (maybe a plug in the bottom of the skimmer?--1 1/2 inch hose)
