truckers boy:
doesnt matter if your trucks old or new you should drain your air tanks on truck & trailer (if possible) atleat once a week…
…no offence but im only 24…
…nowadays most driver tbh are plain idiots.
Bit harsh that fella.
true in lot of ways though, maybe not you personaly but have you read some of the idiotic threads & questions that are ast on this site?
truckers boy:
doesnt matter if your trucks old or new you should drain your air tanks on truck & trailer (if possible) atleat once a week, moisture gets into the tanks via condensation not just through the air dryer or compressor. guarantee atleast one of yous who has posted on here saying you dont bother will become a cropper when the cold does come back by somthing silly as a shuttle valve sticking open & exhausting your air as you try to build it up, which could have been avoided by yous not bein to lazy or bone idle to pull the drain bung on the air tanks to get rid of the majority of moisture. then its left to daft [zb] like me who get called out of bed at 3am to a breakdown were a valve has frozen up. no offence but im only 24 but i was brought up in a proper truckers eviroment with real truckers/fitters my dad & grandad & uncles, who had to fix there own problems & new how to get them selves out the [zb] when it happend. nowadays most driver tbh are plain idiots.
At least you did say (if possible), but from the days of a brass tap to those modern spring loaded buttons where you had to hold the wire in minus 5 temperatures to modern days with automatic drain valves. At least with the brass taps it saved buggering about with new fangled shunt buttons. I have been around lorry folks a long time too young man 
and as for daft lads like you getting up at 3am, thats what you get paid for! 
in the summer i check them about once a month in the winter about twice a week i keep a piece of thick wire about a foot long with the end bent round in a hook shape in my tool locker ideal for the job
hiabman:
I was told many moons ago that it’s good practice to manually drain the air tanks once a week to get rid of any build up of water in the lines/tank.
Has this been a problem for anyone in winters past?
In truth I’ve never bothered.
It’s a simple fact of physics that one of the bi-products of compressing air is moisture, and before trucks were fitted with automatic drains, and air driers, draining air tanks used to be a regular requirement if you were going to avoid the various potential problems associated with moisture in your braking system.
However, since the general and widespread introduction of simple technology to rid the system of moisture, the need to drain your air tanks has diminished.
In reply to the op, yes.

At least some of idiots can spell.
Pot, kettle, black.
I drain my tanks when I get a bit of free time and I’m bored. Mine aren’t ‘pull a drain bung’ they’re press a valve. Kinda like a tyre style valve where you press it to release the air.
Once a fortnight, usually when I leave it for the weekend. Don’t get much out of my newer one, my old Daf used to blow some funky looking crap out though.

On the rare occasion I do that nowadays, nothing comes out. Roll back 20 years and (particularly Volvo’s it seemed) you would be treated with a dollop of grey sludge.
Yes a good 20 stretch and the Buffalo would cover your legs in the sludge in short order, still those days are long gone.
Most of the motors at our spot drain themselves overnight… 
Yes every couple of weeks but not to empty just let some out see what its like, if bad somthing is up.
