What if it Snows?

Is it normal for all air to drain out over night? I cannot find any air leaks but my truck doesnt hold air over night, no idea where its going.

 

Have tried pulling both valves out when it's full after you shut down? Glad hand seals are a usual suspect.
Is your power divider engaged? My power divider switch will bleed off if it's engaged after I shut down.

Pull both valves when it's full after you shut down. That will tell you if it's the tractor.

 

Depends on the trailer. So yes. Its not uncommon

 

I just put new glad hand seals on it . Thats what i thought it was as well as it was blowing bubbles on the red line when i sprayed soap n water on it and the seal on trailer side was shot. Ill try pulling both valves and see what happens. I did notice today when driving the compressor was kicking on much more than usual. Seemed to lose 1 or 2 psi when splitting gears climbing hills, not sure if thats normal or not. I wonder if it could be the splitter is leaking air. I will test both valves first and see where it takes me. Thanks

 

Back in the day, trucks had an air starter.....that's why no one shut them off. You never knew if all the air would bleed off.
Drivers keep an air hose to 'jump off' another driver.

 

Thank god for electric starters greatest invention ever lol

 

It's just the normal noises in here...……...

 

Resoap both gladhands. Check if the inner grooves of the gladhands are clean of old mangled seal,
and new seal can "seat" fully.
