The good thing about the drain as FWC configured it is that it comes right off the very bottom of the water tank, so it will drain the tank almost completely. The reason I want to connect a hose is not to have pressurized water outside (although that might be good, too), but just so that when I drain the tank, the water doesn't puddle right below the door. The way that I disinfect the tank requires filling and draining several times to flush out the disinfectant. All that water draining on the ground forms a big puddle that I have to slosh through as I go in and out of the camper. I figured that, since I'm replacing the valve anyway, why not be able to attach a hose?
Even without pump pressure, the drain faucet is a great place to rinse your hands, fill a dog bowl, etc.
Now, I'm wondering if I would use pressurized water outside enough to add another faucet...
