There should be a valve underneath the tank somewhere. You might have to crawl underneath the trailer to find it. On my 210 the freshwater tank is over the axles (more or less) so you can't see the valve without getting underneath.
Thanks I found it. Now another question. My hot water has no pressure when on city water. Did not have to use the pump on my x160. Is there a different set up on the x189?

you should not have to use your pump. Also, I ran my fresh water tank to the side of my stairs so I don't have to crawl under the trailer, very convenient.
