Does your MytiVac suk too?
 

I have an aluminum frame MytiVac bleeder that I used for the first time this weekend.

When I have the appropriate black plastic fitting on the bleeder it does not hold much vacuum so I need to constantly pump the unit the whole time the bleeder is open. (This also occurs if I take the hoses off and hold my finger over the suction inlet so it is not the hoses bleeding much air)

I was able to succesfully bleed all wheels but it was a struggle to constantly pump the unit to build vacuum during the entire process.

Is this normal?

Mine does not leak like that, I have a plastic one though.
