Air tanks
 
Are we suppose to drain the air tanks?

Air tanks should be drained daily if driven often, always before starting and driving. I have a pull cord on the side that makes access to draining convenient.
You are only draining the condensation water out of the tanks, not the air.

Should all (in my case 4) tanks be purged, IOW, is it expected that they all may have condensate?

Did you route the pull cord yourself, INGENIOUS. If so, is there one cord per tank and which fittings did you use to connect, something like https://www.amazon.com/Control-Devic...s%2C215&sr=8-5?

I think I have my plans for the week :-)

Air going in the tanks is hot, when cooling the air condenses in all the tanks. This can lead to rust building in the tanks and destroying them, thus the need to drain them daily.
Yes, that is the bleed valve you need. You can see how it is situated here:

Even your home air compressor needs to be drained. Any time you compress air it heats up. Moisture then condenses on the relatively cooler metal tank wall and goes to the bottom of the tank. ALL tanks should be drained. On some of my military trucks there were as many as 6 separate valves to be drained. Thankfully they either had cables attached to pull valves or were plumbed to a low point manifold where all could be opened at once.
I have seen a home system in a high humidity location that was probably half full of water and was running far more often than I would expect from the tank size and the use it was under. The owner had no idea he was supposed to drain the tank. It worked a whole lot better after being drained of GALLONS of water.

This video shows 2 days of water in my 60g compressor. Click on ic for video. I hope it works.

Worked for me all the way up to playing and audio but no video showed up.....sounds like a heck of a lot of water coming out of that puppy.

Drain it once every week or two during the summer.

Drain it daily during the winter/humid times/ rainy times

My tanks rarely spit out water, but ymmv

Not sure where you are, but here in the lower right corner of the US, right now is the humid part of the year. Winter is when the relative humidity finally drops below 70%
