Russ,
The eight air tanks on my coach are located: #1 is in the first bay on the passenger side. Sits above the generator blower. #2 is in front of the right side drive wheel in the wheelwell. #s 3 & 4 are the two large air tanks under the front of the coach above the front suspension. #5 is under the rear of the coach just in front of and above the cooler with the two electric fans. #6 is located up high about where the tag axle is located. #s 7 & 8 are within what appears to be one tank that sits above the transmission. On my coach there was a petcock on the left side, but a plug in the right side. I replaced the plug with a petcock. I know it appears to be one tank, but there is a divider on the inside and both sides need to be drained.

Charlie,
I'm not Apple computer literate so you may be right on my directions not working. Maybe some one with an Apple can chime in. I must admit that I'm confused why your brake air gauge would bleed down so quickly, yet the 110V compressor only cycles twice in 24 hrs. Sorry you are so far away.

Hope this helps........................

Charlie,
Sorry I missed you as you went right by. Could have had you stop by and maybe helped you out.
All the tanks need to be drained and then I would replace the air desiccant filter. It is a spin off, spin on filter and is located in the back of the left rear wheel well.
Tanks #1 & 2 can be reached without raising and going under the coach. NOTE: Not all Newells of our vintage have the air tank I have in the first bay on the passenger side which I call #1.
Tanks #3,4,5,6,7 & 8 all Newells of our vintage will have. All of these tanks have to be accessed from under the coach. Raise the coach using the HWH raise function, then BLOCK the coach up in the raised position BEFORE going under the coach. Then locate each tank & drain. Their locations are laid out in post #11.

There is a 9th tank that I just remembered that is round & located just in front of the transmission. It doesn't have a petcock, it just has a needle valve for draining.

Default Draining water from air tanks

Steve,

Thanks for the tank locations. This is a subject I would like to discuss and get some opinions from the forum members.

I did the block and crawl routine and found the front tanks before a piece of dirt fell into my eye It's full goggles next time, if there is a next time. What I don't really understand is why Newell, as careful as they are about most everything, would expect routine draining of the tanks and make it is extremely difficult. Really, how many people are going to crawl under their coach and be able to do this task. Only one of the front tanks is reasonably accessable, the other I am not sure I would ever reach. Could it be that if one follows the proper procedure for maintaining the air dryer there is no need to drain these tanks?
If the tanks truly need periodic draining, how often is the interval? If so, there are ways it could have been made so much easier. Two thoughts come to mind. One would be remotely located operaters connected to drain valves via ss cable and one could pull the handle/ring and exhaust some air/water. Or, electrically with some kind of valve and heater.
Maybe I am just trying to rationalize because I don't want to do.

All thoughts appreciated. Thanks! Russ

Russ,
I'll give you how I handle this & then let others tell us how they do it. I drain my tanks every time I lube the chassis. Every 5000 miles. For me that is three to four times a year. I also replace the air dryer annually. Once I found all the petcocks it is a quick job. Also I cut large wooden blocks that I can just slide under the coach to support it, so that too is quick. Using this method I seldom get any water. Oh and by the way there is a 9th tank that I just remembered that is round & located just in front of the transmission. It doesn't have a petcock, it just has a needle valve for draining.

Works for me..........................

Russ,
I have used these valves on my main air tanks with great success. I bought off ebay for about $40 each. Non-Heated DV-2 Automatic Drain Valve. Bendix# 281923 Hope this helps
On the small tank front of pass side drive axle wheel well cable pull drain valve.

Yes: but I think mine had a 3/8 male outlet on the unit instead of female. I know all I did was take the drain pitcock out and screw this one in which was the same size. I did this serveral years ago. I will try to look up what I bought if I can find the record and will post.
