They drain. I asked him about it. He said they replace the washer every time and are very careful to hand-tighten so they don't strip the plug. I heard the guy under the car call it out after he'd replaced the plug, if you can believe it!
Apparently, they're not happy with the machines currently available to pump, but he said the company has come up with something that will effectively remove all the sludge. He said they'll probably be pumping by next year.
