Water pump airlock??

My Dad has a 2013 Coachman TT (not sure of model) and lives in SC. He was going to use it this weekend so fired up all of the systems and ran water through all of the lines. Problem he ran into was the water pump wouldn't pull water from the FW tank. Pump runs fine but all he gets is a burst of air when turning on a faucet. All water lines are working normally on city water and he did undo the bypass on the WH.

He called Camping World in Myrtle Beach where he bought it and they said it is normal when the TT sits for a while to develop an "air lock" situation. He would need to access the water pump and blow air back through using an air compressor?

Have any of you heard of this? What is the fix? I live in ND so I have never had this issue as it gets totally drained and pink stuff put in the pump. I can't help him, wondering if you guys could provide some guidance/lessons that I can pass along. Thanks!

  • He had the tank full and I was thinking air leak as well. I will also have him check the "winterization" valve on the pump itself. Thanks for the ideas!

    Open ALL of the faucets.
  • Leave a faucent open and let the pump run until water comes out. It does not hurt the pump to run without water, so let it run.
  • Is it perhaps still filling the water heater? That can take a long time and act like you describe.
  • I would check for proper valve set-up and ensure that there is water in the fresh water tank. You might also have him check the suction strainer at the pump and ensure that it is clean. JMO
  • I would check the fittings and water filter to make sure they are tight and not sucking any air.
  • If the camper has a winterization kit there is usually a valve at the pump that switches between the fresh water tank and the line for winterization, is it possible that this valve has not been switched?
