Bleed off Air Tanks (water)

Our Monaco DP has a huge screw on "air dryer filter"
I change it every oil charge.
There are no lanyards, and no mention of any or of any air system service beyond changing that filter, in the manual.

I do have an air dryer which I have changed out about 3-5 months ago. Everything is working OK on my Allegro Bus (Freightliner Chassis).
Thanks again for your response to my question and yes I know just enough of about this issue to be dangerous.

Thanks to all for your input....

Every day you drive it and when you just run it to build up air. You then know if you have any problems with oil or moisture getting in the system. It is sort of common sense and easy to check it. Why not instead of finding a problem between Payson Utah and Fallon Nevada. Could be costly, or worse freeze up.

Every day while traveling.

Snomas,

Two things about your post bother me: "Doesn't SEEM to". Either you get water, oil or white powder out of it or you do not.

"Much water". Any is too much since you have an air dryer on your chassis.

I know this sounds picky, but brakes and suspension components ARE very picky. I know owners who have spend thousands of dollars cleaning their air system/replacing parts after a dryer failure left desiccant powder throughout their system. Lots of valves and other components that don't work well with contaminants in them.

I had lanyards installed 2 years ago since the coach didn't have any originally. I dump the air tanks on a regular basis. The tanks don't seam to collect much water and that is a good thing. If you get/live
in freezing conditions and have water in the lines that freezes up you will possibly lose your brakes!

Since you asked the question, I can only ASSUME you're not familiar with air systems. Unfortunately, this is a problem with many who purchase DPs. Fortunately, you've come on here and are trying to educate yourself on your air system. I've included a pretty good link below that will give you the BASICS of air systems. While many States don't require testing, educate yourself as much as possible including your BRAKING system....Dennis

RV Air Systems

I usually check mine whenever I happen to think of it...no real timeframe. I just serviced my drier and like new again though.

Again, we really can not give good advice without knowing if your air system has an air dryer. If not, the "daily when driving" recommendation in humid climates is not unreasonable.

But, if your air system has an air dryer, this should be a non-issue.

BTW, assume "water separator" means "air dryer". As water separator is another name for the PRIMARY FUEL FILTER.

Our manual says every six months, I think I recall. it has a good water seperater on the system. i wonder if many even think to pull the lanyards. There are three of them on Drivers side below second compartment.
If it is humid or rally humid where you're at drain them every time you think about it. Nothing spits out then all the better.
