I'm trying to help my relative drain a waterbed. It's old (maybe 20 years) and they don't know the brand, nor do they have or remember any attachments or adapters that may have come with it.
Most descriptions I've read online for how to do this simply say "attach your hose to the bed's drain valve" but this one seems to have a non-standard valve. It's too large for a 3/4" garden hose connector. It seems like a 1" connection but the threads seem too sparse and I haven't yet found anything that looks like it would work for attaching the hose.
Furthermore there's also a sort of button inside the valve that seems to allow air out when depressed. I suspect the valve is sealed when it's not pressed.
The bed doesn't have to be usable again after it's drained as we're planning to dispose of it. Should we cut off the valve?
