low drain points

How much air pressure should you use to blow out the lines? I have a compressor that like most can be set at various pressure settings. I am concerned that to much pressure might harm fittings etc. Can I have some experienced airstreamers reply to this before I goof up and possible blow something up.

thanks,

Bob, my Airstream manual says to use "at least 60 psi". I didn't have the guts to use that much and set mine at 40 psi. At that pressure my compressor can supply over 8 cfm. But even that wasn't enough to get all the water out.... I could still hear some trapped after removing air pressure. That's why I used antifreeze.

Regarding Bud's and Jack"s discussions on removing the panel below the closet to access the water pump....I had the same time-consuming experience.... removing trim, screws, and prying the panel out from the walls and up from the ridge of carpet. So once again I called factory. The answer there was I don't need to access the water pump on a regular basis ( like for winterizing by flowing antifreeze through the lines. ). So I don't.

The reason I did access the water pump was to determine why there was a loud viberation somewhere in the system when I ran water from the water tank. The trouble shooting section of the water pump manual suggested the pump could have a loose mount. That was not it and I still have never solved that problem. Sometimes when I fill the water tank full and use that water there is no viberation and after other fills it viberates like mad.

Anyone else with a similar problem?

I would agree with everyone that the water pump access design for the 27ft Safari is poor. I am able to get mine open by using a couple of 1-inch plastic putty knives to slide the edge over the trim. It seems to work as long as you use a few naughty words to persuade it along. I considered modifying the opening but my wood working skills are somewhat crude. I am going to stop at the factory next summer for some warranty work and thought I would see if they had a craftsman that maybe could help make a modification.

Even though the manual said 60 pounds I turned chicken and used 40 pounds. Then still did not feel comfortable with just air and decided to also do the RV antifreeze.

Well, looking at your address, Ruebel, I can certainly understrand why you'd winterize with antifreeze. I did too with an older rig, when living in eastern Montana.

I remove the vertical panel to gain access to the pump as follows:
Remove the 8 screws from the side and top edges of the panel.
Remove the closet doors using the quick release hinges.
Remove the heating vent grill.
Pull or pry the panel towards the center of the trailer approx. 1/2" until it is up against the vertical trim moulding at each end.
Slide the panel up from the floor enough to gain pump access.

I've done this a couple of times now for winterizing and am still thinking about an access door or panel.

Next time I winterize the trailer, I'll have a decent air compressor so I wont be using antifreeze except in the traps.
