Maybe someone Knows automatic Irrigation

I set up a automatic Irrigation system using 20 Halos. 10 nine inch rings and 10 twelve inch rings, adding 10 more twelve inch rings. One 50 gal drum. one pump running two lines at the moment.
I can get even water distribution to the rings that set up. However, after i shut-off the pump it continues siphon water from the drum. What can I do to stop this from happening

Poke a hole in the tube above the water line

Ive had the same issue before, but im curious as to what you mean by "above the water line"?

And wouldn't that mean i'd end up with a water mess when the pump is on?

In the barrel still but above the water line. Lets air in when off so it doesn't syphon

They also have anti siphon valves you can put inline if you dont think his answer sounds right, but hes correct too!

thanks,

Makes perfect sense man, such a simple solution

I also thought of a valve, or an air return line but i thought i was overcomplicating the issue... Which maybe i was doing lol

I use an electric ball valve. It's on the same timer as the pump. Opens when pump comes on. Closes when pump shuts off

I used to flood the basement with runaways. Found out that:
It was a pain in the azz.

Drippers have to be above res water line or it gravity feeds.

Hole in the pipe in the res worked to break the vaccum.

Anti siphon flow valves worked.

I end up going back to a custom dripper flood table layout with the res under the tables. No more gravity runaways.

Good luck

Well all, just to let you know I took a screw and screwed it through both sides of the tubing just below the water line. It worked. The only siphoning is what is left in the tubing. Which ends about one to two maybe three minutes after the pump shuts off. big problem simple solution. Thanks
Now on to increasing the water pressure to feed 30 plants at once.
Currently running 1/2 inch tubing everywhere. the pump size i forget right now. but it is large enough. I get decent dripping. Currently only watering 20 plants.
So I am taking the plumbing approach. I will run 1 inch tubing as the main line and 1/2 inch to the individual plants. this should create pressure in the 1/2 inch lines which goes to the halos. The 1 inch line goes in circle and close off the other side of the tee.

But since I have everything created with 1/2 inch (tubing, tees, elbows and couplings). I am thinking 1 inch tubing running from the pump until it gets to plant distribution which becomes 1/2 inch and runs in circle closing of the tee

I just want that extra pressure to make sure everything is getting a good watering. Right now it takes about 4 to 5 minutes for run-off, some pots are a little early

Well all something weird happen today. I was adding a couple of pots to my system. The main shut off was open. I did not turn on the pump. I cut the main tubing and water started running out both sides, cool I expected that to happen. Added the pots and began to do something else. I never turned the pump on and the water line has a hole above the water.
I started hearing the res filling. Look in the room and 3 or 4 of the pots was watering.
I never turned on the pump.
So I turned off the res line at the shut off and walked away. What in the world happen.
This is the first time this has happened since i poked the hole in the tubing. I also change to a bigger pump. The type you use when the basement floods. It uses a water hose
