Drip System

I have a 50 gal trash can as a reservoir. A sump pump into a 1/2" hose travels out of the top of the can and along the ground 20' and it is capped at the end. About 15 1/4" hoses (2" each) branch off the 1/2" and end in adjustable drippers.

Problem is the system will siphon the reservoir dry after the pump has been turned off via timer. How do I stop this from happening without manually raising the pump above water level (breaking siphoning effect)?

Thanks

Sorry, i don't really know so I deleted my dumbass answer. Consider this a thread bump. Good luck with it.

Well, here are some ideas I came up with...

Raise the water line and have it drip a couple feet.

Dig a hole and set the can down inside.

Make a trap like drain under the sink.

Maybe there is some kind of valve...

I don't really understand the first option could you describe this better?

The solution I thought of was to place a one-way valve on the 1/2" hose (open to the atmosphere) so when the pump shuts off the valve will open and pull air killing the suction effect. Now I just have to find this valve.

Thanks for the replies.

get a antisiphon valve
or also know as a one-directional valve

i tryed finding link to one but could not find but here is link explaining said valve

Common sump pump problem. Oneway valve will work, goto lowes and explain problem they'll have a fix for you.

A 1 way valve would do it. I dont use one, I have a line that has a hole in towards the top of the resivor, when the pump is on I loose some pressure because water comes out that hole. However when the water pump turns off the hole in the line allows air to enter not allowing a siphon to be made.

My line leads into a pvc pipe, this pipe has elbow connectors to make it "U" shaped so it hangs on the resivor. There is another line on the inside of the resivor that connects to the other side of this "U" shaped pvc pipe that leads to the pump. There is a hole drilled in the pvc pipe on the inside of the res and its drilled in there at an angle so when the pump is on it sprays a jet of water down into the resivor. When the pump is off air enters the hole and no siphon.

I've been wanting to do this forever! I have an indoor tent and have a 64 gallon trash can with an aerator, (reverse osmosis ordered!!!), just outside the tent, I've done outdoor drip systems before but don't know much about pumps. My boat has a pump that sucks water into ballast tanks to weight the boat down for watersports, I've been searching boat sites, but all are way too expensive. I want to drop a pump in the reservoir and run hoses to each plant and water every 2 days or however needed, BUT how do you control how much is being watered? And ...Is there a way to use Nutrients this way? I just drop my watering canister in the trash can and fill her up and manually water. I'd love to leave town and not worry about having one of my fucking idiot friends come over and over water the fuck out them or not care for them at all.. If anyone has a journal please msg me.. +++REP for any input!!! ???

Well, there ya go. There is a valve. I was just thinking if you raised the feed line higher then the water level and let it drip a couple feet down when you water.

I think the valve is better.

I thought to do the same thing after deciding I'm damn tired of going to the hardware store every day. I'm going to punch a 1/4" tubing connector into my 1/2" line. That should be a reasonable size, right?

Out of curiousity is the one-way valve inline with the tubing?
If it is does the siphoning not cause it to open because of insufficient negative pressure on the far side of the valve? The fact that it is one-way doesn't seem to matter as flow from pump and siphoning pump are in the same direction.

Or does the one-way connect the tubing to the atmosphere? This would allow air to enter tubing when siphoning creates a negative pressure.

Thanks
