How Condensate Temperature Affects Vacuum - Oak

Lower steam pressure equals a lower AMOUNT of steam produced, which means there is less steam to condense. It follows that there is also less steam leaking past the bad trap(s), and this results in a lower condensate temperature, which allows the vacuum pump to pull out to a higher vacuum. This higher return line vacuum can offset the lowered
