Where's the water?

Hey everyone,

Need your help. I just brought my Trailer our of storage to dewinterize. All is working great...last step is to add water and pressurize lines with pump to make sure all is good, not leaks, etc. I add water to the tank, turn of pump and first thing is notice is that pump sounds different. I can't explain it, but it sounds different and definitely louder. After a few minutes of waiting for the lines to pressurize with water, nothing. No water anywhere. I open the faucet and air is coming out, which eventually stops. I close the faucet for a minute and re-open and again air. I look at the pump expecting to see water or somthing around it, nothing - dry! No water anywhere. What am I missing? Any other tests I can do. Am I forgetting something silly? Ahh...the joys of Rv's :)

p.s. it doesn't get too cold where I am - Tacoma WA (area). I did blow out lines in October and added winterizer fluid down the drains, etc.

  • If you're getting air with the pump running, then the pump is trying to pressurize the system. Try filling the tank to increase the head on the pump, but frankly, these positive displacement type pumps don't need much head pressure. Open all the faucets and water outlets one at a time and let the pump do its thing, or pressurize the system with city water. Have you filled the water heater?

    Sounds like your valve is still set to the winteriz position which is not letting the pump siphon the water from the tank.
