I am new to the pool world! I have a WhisperFlo 2 HP pump. Trying to prime pump for first time this season - filled pump strainer with water, should be ready to prime. Motor starts for a few seconds and then switches off. The instructions say I should "open the air release valve" on the filter. I have checked and rechecked the instructions - I can't find an air release valve!
Can anyone help? A photo would be amazingly helpful!
