Boscoe ,i just want to say thanks,you the man!!!! It was exactly as you said. On the side of the vst tank there is a check valve. When i had the tank off before i cleaned it and was pretty sure i cleaned that little screen and the check valve. When i took apart today there was a small piece of dirt on the ball bearing in the check valve not allowing it to close. Put it in the water tonight and its running like a dream . Future reference the amazon pump would have worked just fine . Cant thank you guys enough
