So I took a test last night and I have a vvvvvvfl kinda hard to see in pictures but it's there and no it is not an evap line either. They say to use pink dye because blue suck but I have never had a problem with the blue dye. Anyways I took a test this morning and there was nothing.... so anyone see anything? What do you think is going on please help me
