Hey,
I've tested 3 days in a row, friday there was an extremely faint line which wasn't viewable on photos. The line is really faint, but I see it. When I look back at the test after some time, I see a line still but it looks thin and I think It might be an evap line. Ive attached photos of test within 5 minutes and test of thin potential evap line. Just wondering what you think? Could it be a false positive?
