Hi, I can't understand why I'm losing prime while vacuuming. To set up the vacuum, I turn the pool off, put the vac adapter in the vac hole of the skimmer plate, put the skimmer cover down inside the skimmer, turn the pool on, and it keeps prime. However, if I attach either my regular hose to vacuum, or the Aquabug hose to vacuum, (after, of course, bringing the hoses to the return, filling them with water, keeping them underwater while attaching them to the vac adapter) I lose prime in about 1 minute....I am using 2 different hoses, so what are the chances that they are Both cracked somewhere? I would appreciate any ideas....
