Air in water lines?

I was looking for help for my pressure issue too. Pump makes a lot of noise then goes really loud and working hard, you can hear it pick up the water and then we have preassure but, bathroom is low while kitchen is slow and sputteres like air in the line...even after 10 mins of running it. All works perfect on City hook up. Has any one had this contant air in the kithcne sink and has or thought of upgrading the pump to a biger one ? (if thats possible)

When warm temp came filled F/W tank,water on top of the enclosed under belly from leaking F/W tank,and the F/W pump didnt work either! Both replaced. Time of year ,makes a difference! Youroo!!
Picked up my 06 flagstaff in the winter of 07 and they had water in it to run all systems. (Guess it depends on how lazy your dealer is)
Then after pdi they drained and winterized it.
So true in my case and not so much yours.

You really should start your own post instead of piggy backing on another.
You'll get more traffic and answers.
Year make and model would help to.

I am thinking you have a loose connection and while it is not so loose as to make a mess; is is loose enough to suck air under suction pressure.

Maybe a rolled seal or cracked bowl in your inlet strainer.

Just got email from the dealer, they told me to confirm that the in and out valves are parallel to the pipes and the bypass is at a 90 degree angle to the pipe flow. Will check at noon. For some reason I think this may be the issue. during the resale PDI after winterizing they may have left the bypass open

I don't think the valves around the water heater have any bearing on your problem as everthing is fine on city water. Has to be a suction problem with the pump...is there a antifreeze suction line open or is there enough water in the water tank?

First off my dealer is (NOT) lazy! Next it was 10 F when we picked up the trailer,but roads were dry and clear (no salt). What I stated was fact about the post. Youroo!!

I was referring to the fresh water tank, not the water heater...sorry for the confusion.

My experience has been though the tank level monitor says 1/3 full, the pump will not draw from the FW tank as the line out is not on the tank bottom.

Lifting the pressure relief valve in the outside WH compartment verifies that the WH is full should you need to check.
