I know it’s a dumb question but I’m asking anyway because I can’t get a straight answer. I took a test a couple days ago and I thought I saw something. I looked at it again and it definitely had two lines. I know that the test is invalid after a certain amount of time however a lady I know went through the same thing and she called the company and they said that if it’s red it’s most likely not an evap line. I plan on testing again tomorrow. What are your thoughts on this?
