I have a leak in my bathroom. There are old water stains there, so it must just be that once in a great while, something up there starts getting filled faster than it can drain. I'm just putting a bucket there. It's only a slow drip...and I don't own this place. ;-) I'm just gonna keep repeating that...
Getting ready to head off to church.
It'd be worth a look to see if there's something that's plugged up, when you get back. Or tell the landlord.
