I have a simple question. I need to clean the pump filter basket, but I only have one ball valve before the pump, and none after the filter. The pump and filter are below the water level. If I close the pump valve is this enough to keep water from flowing out when I remove the pump filter cap? I watched several YouTube videos on this, but I'm just not sure I can just close the one side and take it off.
I can't get the directional jet fitting on the return unscrewed to put a plug on it.
More background about me...I'm brand new to pool maintenance. I had a company open the pool for me and teach me as much as he could about my system and what the parts do. In general I know about flow and gravity and physics, but not much about pool pumps and filters. I'm determined to learn how to do this.
Thanks for your help!
