Vent the pump into a bucket 1/2 full of water. Put a couple of drops of
dishwasher detergent in the water to aid cleanup. You should test for
foaming, but machine detergents shouldn't foam.

I believe I would find a different vacuum pump. HVAC pumps are designed

the pump before the epoxy kicks. You also don't need that high a vacuum.
When you get much above about 15" Hg you run a risk of squeezing to much
resin out of the layup. A pump rated at 24" Hg will give you plenty of
headroom.


I know but this pump is quite quiet (quieter than a vacuum cleaner).

The first thing I did was check the oil level in the window on the pump
when I went it and it hadn't budged. I suspect that a little oil goes a
long way when it comes to making a mist.

I did keep the vacuum level at 10-15" during the time the pump was running
but thanks for the thought.
