FYI: I just picked up a hose adapter at the local hardware store. It has two sets of threads: the standard garden hose threads, and then it steps down to some smaller threads. I'm not sure what the smaller threads are intended to fit, but all they do for me is make it impossible to connect the hose without removing the washer. Maybe it'll work fine with other hoses, I dunno. It doesn't leak too badly without the washer, but I'm going to get a different one.
