I am a new pool owner and when i try to vacuum using a hose and the skimmer, it seems i have trouble getting enough pressure. i was told i need to shut off the other skimmer to get more pressure to my skimmer i am using. How doi do that? Or do i just need to cover the other skimmer so more pressure builds?
18,000 gallon pool, two skimmers, I am using the skimmer closest to the pump.
