Wet tank drain??

[bs4104]

On a 102a3 there are two air tanks bolted in front of the front bay with no bottom drain hole. They both have a drain valve 3" up the side,
is there a tub to go down or does it just keep any water that is below this drain?
Has any one check in to this???  BgS

Never thought about it. I believe the air when drained will blow most out and then leave open overnight to gravity drain because the air sometimes will blow right past all and leave a lot inside.

Seems like everything that i have ever seen with a drain valve always has it at the lowest place on the tank.

You would think that most any air tank would be designed and installed so there is some way to drain out all the water, muck and stuff that eventually accumulates inside.  Could the two air tanks have been reinstalled non correctly?  Just wondering.  HB of CJ (old coot)

Stock MCI tanks,  I have always assumed they have tubes to blow out from the bottom when there is sufficient air pressure.  It's a good system, tanks that drain from the very bottom are quite prone to clogging and blockage.  Mine sure seem fine, they are exactly the same as those.

The tanks on our 102 C3 are exactly the same way. A poor design in my opinion. Raymond

I haven't looked at mine in particular but from the pictures it seems the tanks are at about the same height from the ground as the suspension.  If the valves were on the bottom road debris could impact the valve which would be a weak point, and break off, if located on the bottom of those two tanks.  The tank for the rear brakes has the drain on the bottom so there must have been a reason.  It wouldn't be good to have a drain valve break off while in transit and start draining the air.

     Some tanks have a row of 3-4 90º-twist valves with a 1/4" line going each one to the low point on a tank.  If you don't want to/can't reach a tank drain, all you have to do is crack open each valve -- if there's water/oil/crud in there, it will come out.

My drains are on the bottoms of all of my tanks......the odds of something breaking them off are probably about the same as winning the lottery.
