I just bought a Viking 21 foot travel trailer. I tried out the water for the first time on Memorial Day Weekend. I connected the water spout at our site to our "city water" connection and waited for something to happn. I also turned on the water pump, then realized after reading the manual that you only use the pump if you have filled the freshwater tank. I kept the spout on for about 15 mnutes. The toilet and shower in the bathroom had water, but the kitchen sink didn't. I checked under the cabinet to see if there was a cutoff or on and off value, but there was none. I recently had some electricity work done underneath the trailer because some electricity wires had gotten burned. I don't know if this is relevant. I turned the water spout off after 20 minute; still no water in the kitchen. Anybody know what the problem might be? Thanks.
