Don't try this at home, kids...

...if you fill the bottle as normal, then hold it with the valve downwards (at abour 30degrees) away from your body, and open the valve, as you rotate the tank (as if you were screwing it into your gun) you will see liquid coming out at some angles, not at others. If you do not have an anti-siphon, chances are you will only have liquid coming out.

Please make sure you are wearing full-fingered gloves when you do this (the tank and CO2 jet are very cold), and you are outdoors, and you cannot be pointing it at anyone.

A slightly safer method, which doesn't require filling the tank: slap the side of the bottle with your hand and listen. Anti-siphon tubes can be heard to ring for a few seconds. Problem is, you can't tell which way it is pointing - anti-siphon installation normally requires that you have the gun to screw it into present, because you need to know how far in the bottle screws so you know which way to point the anti-siphon.

On reflection, the chances are that if whoever you bought it from didn't ask you about that, it's not anti-siphon.

I bought the bottle with the marker, but he got it secondhand also so he doesn't know...

I'll try the tapping thing tonight... thanks!

 

[How]

checking for antisyphon, the only real way is to take it off and check. If you take it off and it does make sure you put te bottle back on with the antisyphon tube the same way up as i was before. Also use plenty of loctite.

ill tell ya wat, your NEVER touching my marker How.

You DONT have to take off the valve to be sure. anyway if you did it it would take 3 weeks before you plucked up the courage to ask someone to fix it for you.

Rabies is right. and its a quick test.
Bearing in mind that an Anti syphon tube is a copper pipe shaped like a J where the top of the J is in the valve, and the bottom is in the bottle. So at some points it will be facing up, and some points it will be facing down.
With an on/off valve -
Fill the bottle. Now open the valve till gas can be seen coming out. now roll it round slowly in your hands. As it turns you will see that there is a point in rotation where the vapour is clear, and another where it is snowing.
When the vapour is clear, the anti-sypon is in the right place.

If the bottle is pin valve.
Fill it. put in onto your marker, and fire the marker, and turn the bottle as above. the same will happen.

Another trick, is if you look really closely, sometimes there is a carefully placed mark (dent) on the outside edge of the hexagonal part of the valve, this is made by the tool that bends the anti syphon. so instantly donates the "top point" of the anti syphon. (which should always be facing up, for the anti sypon to work)

There are also 3 kinds of CO2 bottle.

Anti Syphon - which i hope you know what that is now.
Syponed - Which has a tube in it which INTENTIONALLY draws liquid. this is usually for older markers.
Standard Valve - which just has the hole in the back end of the valve and no clever tubing.

If ya shake an empty CO2 bottle and it rattles, its either syphoned or its a BROKEN Anti syphon. ive learnt from experience.

Hope that essay helps

BTW all of that i could have shown you in 30 seconds. the web isnt the best medium for all things.

Wow, thanks Billy...

Now to get slightly back on-topic; if it turns out my bottle DOESN'T have anti-syphon, would I be able to buy one at Sparklies, and more importantly, would there be anyone there able to fit it? Or is it something that's best done in a workshop?

I moved this thread because it belongs here and not in the Tech Room.

I am keeping my mouth shut......

Blimey ginga one, there's a first

 

[Billy No Mates]

Ginga - is that a promise? or a threat?

ive probably made some huge error in my essay. but then i guess i have to maintain that i have no mates. You are god of all that is unholdy, and violent, and a master of whit. Enlighten the misguided ones with your knowledge. (or just spout useless drivel as usual)

QuackingPlums - as for buying and fitting. It "can" be done at the site, but it makes everyones life easier to just get it done by someone like belsales or smartparts.

Well I gave my bottle a tap last night, and couldn't hear anything. I then shook it quite violently, and still nothing. Does the bottle need to be empty to hear the ringing, cos I think I've still got some CO2 in it, and wasn't about to empty it in my living room (my gf would probably take offence at that... shortly before asphyxiating...)

Thanks for the advice, I was only asking in case it was a trivial job. If not, I'll try to visit smartparts and see if they can do it for me before the 15th....
