How many psi are you running through it? I got my pump to do 29hg of vac, but I had to turn the thing up to 100+psi.. 22 is not enough
Heres a calculator for the boiling points of water at different vacuums..

You have to convert inHg to mmHg and then subtract from 760mmHg (atmospheric pressure) to get the absolute pressure in mmHg
