slow basement drain

There's your answer. You need to have the drain cleaned. Call your favorite drain cleaning service. You *might* be able to rent the right tools, but it's a nasty job.

Rueful chuckle. If you are lucky, you can clean them. Mine here didn't work, so I got the guy with the auger in, and he gave up after an hour. Teakettled and/or rusted shut. House isn't worth the cost to bust up the floor, so I'll probably mud them over come sale time. The old drywell standpipe on the wall for the washer doesn't work either (shows up an hour later coming out the floor drain), so I had to route that to the septic drain instead.
