Staying aired up

[Jimbabwe]

How long should I expect my truck to stay aired up before finding it back on the ground? 24 hours? Several days?

Jim, what are your findings? As I mentioned on Fb, mine stays put.
I park outside laid out 99% of the time (when I am out)...but my truck stays garaged 100% of every day if I am not driving her

Ahh, I posted this at the same time as on the FB version.
I'm wondering why when Anthony tightened the filter and the 4 screws on the one compressor's top, it stayed aired up a bit longer than an hour or so...a few hours. But we weren't around over the past 3 days of the Christmas holiday to see when it hit the ground. But still, that's only 3 days, and it's not one wheel but the whole truck. Any ideas?

is the tank empty also?

[Jimbabwe]

I don't have a gauge on the tank, but the whole truck goes down.

Air had been heard coming out of the filter on one compressor on Saturday.

yeah, you need a one way valve after your compressor then.

Keep in mind that on the manifold valve assemblies, the valve itself is held closed by back pressure in the tank. If the pressure in the tank drops below the pressure in the bags, the system will bleed down.

I would heed Broeys advice and make sure the check valve in compressor line is working properly.

Weeks, maybe months on mine. I always park mine aired up to ride height. If I have a leak I want to know about it before I go out. I have had it parked for over a year now, and it was several weeks before it slowly went down.

Thanks. I don't have separate check valves after the compressor, only the block of eight valves which I assume have the job of doing just that. Unless the problem is what Nate (or Dave!) is referring to and I need to install check valves.

The check valve isn't necessary, but always recommended. It just helps keep all the pressure pushing back on the compressor itself. Always a good idea.

If you have a leak behind the valves (between the manifold and the compressor) the whole system will bleed down.

A system with no leaks should hold air indefinitely. There will be a little loss of pressure over time... just like on a tire. But it should definitely not be noticeable over a few day period.

I thank you. My truck thanks you!
