I bought the Adam’s standard foam gun. When I tried it out, I’d get a second on good foam strong stream an then not even enough water if I hold it next to my vehicle! Tried different size orifices different amounts of soap to no avail? Called customer services they said send a video. I did. Instead of telling me the problem they are gonna send another. Which I appreciate. I read the ratings after the fact and it seems to be a common problem?
