can someone please explain what an anti siphon valve does when used in a drip feed system and also where it would be placed??? 
i am very confused on this matter... :/

It's basicly a 1 way valve. Let's say you need to have you hose above your drip lines. if you don't use it at the highest point you creat a syphon. Water will not stop. But if your pump is lowerand hoses don't go above your drips it's not needed

but wouldn't a non return valve do the same job?

Not realy. I just said it in basic terms. It has a valve in it that reverts air back in to it to stop the syphon action. Non return valves don't stop air or syphon. As it is created befor the valve or after the valve. Easiest way is keep everything above you res but below the drip lines.

It prevents water from being siphoned from the table when the pump is not running.can someone please explain what an anti siphon valve does when used in a drip feed system and also where it would be placed???
In a drip setup, you could use them to keep the system primed.

A drip system can't drain a table imiters are above it. It's used to stop the flow of water from flowing. Using air.

so in this kind of a set up, you wouldnt need one...?

If your drippers are always higher than the reservoir level and the water is pumped, as in your drawing, the drippers will provide the same function as air will enter there and water will flow back to the reservoir when the pump shuts off.
If the containers are ever lower than the reservoir level you will need to provide a means of stopping water flow because just shutting the pump off will not work. The water in the containers will try to meet the level in the reservoir and the flow is maintianed by gravity.
In your diagram, if it were me, I'd provide a drain line from the containers to the reservoir. The system you are showing might work but you are asking for a flood sooner or later.

yeah, sorry... my last drawing was just trying to get the point across regarding the anti siphon valve... the drawing attached is a better representation of how my set up will function. surly the non return valve would stop the siphon effect from occurring with this design and keep the system primed??

this is the actual setup

As long as your pump is always under water you won't need ether. Pump filter then emitter. You will be goo with that setup
