Just make the transition and go out through or under the shop and run whatever hose length you need to a low spot and you have yourself a draining shop sink. I kept thinking that I want a drain to the septic tank (that will happen later so I can have a stool in the shop... I may opt for a urinal just for piss and giggles) and I wanted to do a permanent drain setup. This will be fine for the time being and I have the use of water. Right now it is well water, but I plan on tapping into the domestic home water so I have softened clean water. I may even hook a RO so I can have nice clean water to make wine..... But we won't mention the to the wife until the time is right.
