    While I think you're just trolling with this post, for the sake of some new drivers that might see this, I'll bite & answer.
    By not draining the air tanks, the condensation buildup will eventually lead to getting water in the entire air system including brake lines & will not only cause damage from the water itself but in the winter, the water in the entire air system will freeze.
    1) You wont be able to build up air.
    2) You wont have brakes.
    I know of times when a driver will have brakes when doing his pretrip, then after getting on the road, the lines freeze & no brakes.

    That's why you need to drain your tanks to get rid of the water. It stops water damage in the air system & it prevents freezing of the air tanks, air lines, air dryer, brakes etc in the winter.

    I have talked to many drivers over the years that didn't know that the desiccant element on their air dryers needed to be changed periodically. Heck, didn't even know the dryer had one. It comes down to knowing your truck and staying on top of the maintenance.

    I now remember that my air dryer filter is capable of separating oil and water. I took a picture of it a couple months ago while I was replacing my entire air dryer/governor. My previous company would replace the air dryer filter along with doing a power steering oil change every year.

    Huh. It just occurred to me that the reason these systems are called air dryers is because they dry the air in the system!? How did I miss that.

    I found a Bendix document saying that reservoirs (air tanks) still need to be drained every 25,000 miles or 3 months (whichever comes first), and the air dryer filter needs to be replaced every year.

    The air dryer has to work. Period.
    Draining moisture at the end of a -30 day is just blah blah. The moisture is long frozen solid before you pull the valve.
    In eight years, I've drained my tanks twice when I changed the dryer cartridge. Now I just get it changed during pms once in fall to have it in working order for the winter.
    Never had a frozen system.

    If you are so worried about it, and you want to drain the tanks of water and junk, just go here, order one for each air tank and have them installed.

    Hi Ridgeline! Thanks for recommending the Expello valve. Full disclosure: I do work for the company. Don't want to be commercial here just want to let you know that in our experience 1 valve on the wet tank does the trick.

    Whenever I check my air tanks nothing but dry air comes out.
    Which means the air dryer is working as advertised.
    If you have lots of water blowing out, you might want to get the dryer replaced.
