    Hey everyone I made a homemade milk pump based off a YouTube video.

    It's made from a automotive brake line vacuum pump, some small plastic tubes, a syringe to put on the teat and a mason jar.

    Well I'm getting pressure when I put on my mini Lamancha doe fawns teat and no milk. The pressure gets up to 12 psi which is max. It has pressure gauge.

    She is in milk. Any ideas what I'm doing wrong?

    How big are her teats? Is it continuous pressure?

    Her teats are kinda small but in the YouTube video I watched they said as long as you can get vaccumm pressure it should work. I'm getting a steady 12 psi.

    I have found that small teats don't work for a pump or work poorly. Also depends on how small the orifices are.

    Do I need a smaller syringe?

    I will take a picture and post it later. She has a 3rd teat or a udder scur. Not sure how much that effects anything.
    How does that work with a milk pump if you have pressure but a small vaccumm leak will that effect stop it from pumping?

    You can't have any leaks.

    Ok so I might have a leak stopping it but good psi?

    I'm not sure since it has been a long time since I have used a milking machine.
