Rez overflowing through drippers

[Cuban Strain]

Ok so my buddy's rez is emptying through the drippers because his table is on the floor and the water level is higher than the drippers, so it basically just siphons out little by little. Kind of like a Blumat set to flood... Is there a way to keep the water at bay if your rez is higher than your table? I was thinking like a breather type of attachment.

Any suggestions? Thanks in advance.

I guess this should've been in the hydro section but I grow in coco...

you can drill a small (1/16") hole in the line from the pump INSIDE the rez and ABOVE the water line. this will break the siphon but you will get a good spray out of this hole when the pump is on. why is the tray lower than the rez? is he using a barrel ? is he running a pump back into the rez?

Naw it's dtw and the flood table is on the floor and drains out. He's using a brute 32gal barrel as his rez.

then the hole for the siphon break will work. if he puts the hole on the inside leg of an elbow and installs it so the hole sprays down into the rez it will work out. if you put the hole in the hose it can get messy easier (not so predictable). you will get build up so clean it out with a tooth pick once a week and you will be fine. peace

Thanks man! You know what the funny part is? He had is working just fine, the hise was taught as it went up to the ceiling then back down to the table. It would drain everytime the pump would shut off. He had to move the rez, so he made the hose longer and now it doesn't drain... Go figure. When it's not Peter, it's Mary!!!

 

[Cuban Strain]

Well he's kind of reluctant to drill the hole in the hose because he had it working without the hole. Does anyone know about an anti-siphoning valve? I think this may be the ticket.

i'd be more leery of the valve (if you're talking a check valve) - more moving parts is just another point of failure. those suckers gum up

the anti siphon valves for sprinkler systems, if you look at what they're actually doing, they're doing the same thing as the drilled hole described above, they just cost 20 bucks to do it.

 

[Cuban Strain]

Yes I was just looking at a backflow preventer, which I think is another word for check valve. So I should just tell him to spare the 20 bucks and drill the hole which is the same exact thing as the anti-siphon valve?

Thanks for your advice. Any other suggestions?

He's anal so I see him spending the $20...

Float valve works

 

[greenmatter]

all of the above will work, some people like gadgets even if they are ultra basic. if it works it works. if he is cool being out $20 for something out of a box so be it. just make sure it stays clean.

 

[Cuban Strain]

Problem resolved! Thank you all for your help. This is why this site rocks!!!

Now he won't be going through a 100L resi everyday!! Well it's not it's that bad as he kisses it so each resi costs about $4.00.

He got this:

he put it right were you said to drill the hole, Matter.

great idea. simplicity rules

Hey GreenMatter.....How does that work? I would think it would just siphon through the pump AND the side tube. I can't see how this stops siphoning.

maybe it is just the picture but if the end of the "side tube" is not under water it creates a siphon break (air gets into the line and breaks the siphon). again when the pump is on water will be coming out of this tube/hole. that is what i think is cool about evlme2's photo, the drip line would be very easy to direct back into the rez. way better than drilling a hole in an elbow, which is what i have always done. won't get the micro sprinkler effect either when it starts to clog. great idea IMHO

 

[Cuban Strain]

For Real! Great Ideal Evlme!! You never cease to amaze me...lol

 

[BlindDate]

Ahh...Got it! Although, I would think that the open tube will create a pressure loss on the drippers.

Yes BD , it does reduce pump/dripsite pressure , but anti-siphons are highly necessary with smaller pumps and irrigation type feedtubing hence the vacuum lock in original post about rez draining out.......

Pretty much "Irrigation 101" but not many folks read the instruction manuals anymore.......

Works as anti-siphon as well as a "bypass" as Heath Robinson called it way back when I saw his rez for the vertical racks.......

He used an oversize pond pump and above the pump was a T still inside the rez , with an elbow on the end of it blastin juice back down into the rez for major dissolved oxygen , but it was also relieving pressure on the bigass pump , while also acting as anti-siphon preventing vacuum locks in the plumbing lines....

He had control valves on each level of plants so as head pressure dropped the higher it was pumped , each plantsite/container could have equal flow and pressure by dialing the pressure on each level with the individual control valves.....

Anti-siphon/rez oxygenator....

Peace.....DHF..........
