Do anti siphon co2 tanks look any different than regular tanks? Does anyone have pics of one I could see? Thanks

[Chaos]

They look exactly the same ,unless it has a label stating it's a Siphon tank.Main thing that's a give away is if you shake the tank side to side ,you'll hear the siphon tube clanking around inside.

[Wollffy]

Simple, thanks Chaos.

[c6quad]

if the tank is empty you'll hear the clanking. it's hard to hear on a full tank though.

[Wollffy]

Actually now that I am shaking this bad boy around there is no clanking whatsoever. Is this the only way they can be antisiphon? I hope I am wrong or there is an McBe'r with faulty description in his sale thread.

A syphon Tank will clank.

An Anti-Syphon tank won't.

Thanks Darkstar cool.

In a siphon tank, the fitting at the bottom of the siphon tube often clanks back and forth as you shake it.
An anti-siphon is a small copper tube affixed to the underside of the valve (inside the tank) and is indistinguishable from a regular Co2 tank unless it has been labelled as such.
The copper(or aluminum) tube is curved upward when the tank is in a horizontal position. The critical part is that tanks don't "bottom-out" at the same orientation in different ASA's so an anti-siphon on one marker may not be on a different marker.
It's a common practice when installing them to mark the position on the outside of the valve, so you can see when the tube curves up instead of down.

I did not make this drawing, but its a good one:


Siphon tubes are easy to spot since they will make a "clank" when you shake them.

Anti-siphon tubes are impossible to spot, unless they are specifically marked.
You could fill a take, and dump it at certain angles to see which positions shoot out "snow". But this will be very inconsistent since there is NO STANDARD for anti-siphons, and they are configured in a variety of methods.

The best method is to just remove the valve.
Might as well since that would allow you to adjust the anti-siphon so it matches your ASA, or... intall one if it does not have one.

The only way to be sure if it's an anti syphon is to remove the valve like HPL suggests.

Also it would be silly to make an antisyphoned tank and not mark the "top" side so it can be checked to ensure that the gas pickup is in the proper spot. Besides knowing where it is allows you to see how it fits on other markers.
