Took delivery of a new 262 two days ago. Started putting things together today. The water pressure is set at 45 lbs (new guage). Water comes pouring out of the pressure valve overflow hose. I shut the water off, spun the valve release knob a few times, then turned the water on very slowly. It still comes out of the relief tube. The dealership claims the RV was winterized. So is there a process I should be undertaking, am I missing something? Thanks for any thoughts. I can't get to the dealership until Monday so I thought I'd reach out to the brain trust.
