Here is a great working and functional water aspiration vacuum pump. Saves a bunch of water compared to faucet aspirators!

I have tested this and confirmed it is able to pull a good vacuum. I was able to pull down to -27 in hg in just a few seconds. This was also with room temp water; if you used ice water, potentially even salted, I bet you could get down to 10mm hg or so (have not tested myself).

The only flaw I can find is the plastic clip holding the drain hose upright is snapped. This was easily remedied with a loose zip tie. Functional, but not the most aesthetically pleasing.

It includes the pump and reservoir, along with the two hoses w/quick connect fittings, as well as a chemglass y adapter. The vac gauge is not included.

Please message with any questions!
