No adapter. Just hook your hose up to this thing.
The rpod has 2 water systems, access to which are right beside each other on the outside of the pod. The one you are using apparently, is the onboard water tank system. You fill it up until it overflows, drive to your campsite, turn on the water pump, and it pumps water from the holding tank to your sink or bathroom.
The other system, is the city water hookup. No adapter needed, assuming you have a hose with a threaded end. Just screw the hose into the thing that exists on the side of the pod and turn the water on at the at the campsite hookup. You're done. No need to turn the pump on. This works without water in your potable holding tank and does not use the pump. It uses the water pressure from the campground water hookup.
