Parts washing sinks need their own drain logic

A parts washer uses solvent, not water, and that distinction matters for where it drains, or more accurately, where it should not.

A standard parts washer is a closed, recirculating system, not something that drains to a sink at all. Solvent gets filtered and reused, and spent solvent goes to a licensed disposal or recycling service, never down a drain.

A separate hand-washing sink for the crew is a genuinely different fixture with a genuinely different drain requirement. This one can drain conventionally, but it is worth keeping physically and functionally separate from anything touching solvent or oil.

Floor drains in a working shop need a real oil-water separator ahead of any septic or sanitary connection. Wash-down water picks up oil and grime from the shop floor, and that cannot go straight into a system built for household waste.

Waste oil is its own category, kept apart from everything else

Used motor oil and hydraulic fluid from equipment repair need to be collected and disposed of properly, separate from any drain system entirely.

Store waste oil in a dedicated, labeled container, never anywhere near a floor drain. Most areas have collection programs or services specifically for used oil, and using them is straightforward once set up.

A drip pan or containment area under equipment being serviced catches oil before it reaches the floor at all. This is a cheap, simple habit that prevents oil from ever becoming a floor drain or septic problem in the first place.

If your septic system serves both the shop and a house, keep shop wastewater as separate from the household side as the layout allows. A household septic system was never designed for shop-grade contamination risk, even with good practices in place.

None of this needs to be complicated or expensive to set up properly. Most of it is habit and a few dedicated fixtures, not a major construction project.
