Abstract	A recirculating water vacuum pump was constructed from inexpensive materials. The recirculating water vacuum pump has a smaller footprint compared to many commercial models and features a novel, 3D-printed water aspirator pump that also functions with a standard laboratory faucet connection. The performances of both the recirculating water vacuum pump and (faucet) water aspirator pump are comparable to commercial models. The total cost of the recirculating water vacuum pump is approximately $44, excluding the cost of a 3D printer and filament. (As Provided).
