RDWC help - overflows...

designing the system right, so that there aren't any overflows.

I've got about 6x 160gph pumps and 2x 250 gph pumps and several really great strong light-proof 20 gallon rubbermade buckets. Each rubbermade bucket has 1/2" threaded pvc ball valves already leak sealed. I use black 1/2" flexible tubing, I have the adapters that thread into the ball valves. I also have 50 or more feet of the black 1/2" flex tubing.

I find that whenever I connect the pumps and try to get this thing tested, I have an overflow.

I've tried connecting the stuff a few different ways, but obviously there is something going on with water pressure that I don't know shit about.

I've been looking for RDWC how to's and diagrams and help threads and also looking for rdwc ...welll whatever.. I'm scouring the internet with our favorite search engine but its hard to find info.

One piece of info I've found is that the tubing is not prefered, due to potential for kinking. Well, I understand that, I can run pvc later, I have the pvc and I know how to glue it, so thats fine. I just don't know how to connect this thing.

Adding valves is an option. Right now each bucket has 2 valves on the bottom. If I need to add some higher up, thats fine. If I should install pumps in the buckets or just install pumps in the res (my preference is just to install pumps in the res, so no roots can clog), I can do that. If I need to add valves to the res, fine. If I need to install them in the buckets, fine.

I've thought about a re-cycle timer also, but not sure I really should jump over to purchasing more hardware when I probably have what I need.

edit: by the way guys this is only for a 3 bucket setup. Maybe 4. Maybe 5 next grow cycle. So really the resevior has to be upgradable or I can install the extra valves (if their needed) now. I have 6 buckets, I plan on never using one of them (i think I overpurchased.. but I can live with that). But let me know what is the simple way to do this and meet my requirements. Thank you all.

hey there.

I hooked up both drain valves on my grow buckets (the two in the corner) to a spare one and also the pump/resevior, just to see how fast they drain off.

I think I know what my problem is. There's nothing magical here. The pump needs to pump less volume than you're capable of draining. Thats it. My draining capability is poor right now. I need to hook up some 2 or 3 inch PVC drains to these buckets and send those back to my res and I should be good to go. I tried to get by with 2X 1/2" drains with tubes, but those drain out too slow to keep up with the speed of the pump. They do seem to be draining just fine, they are just slow. During the course of my testing as you can see inside of my bucket I implemented a tee, so that my pumping capacity is halved (rather than use 2 pumps), I was hoping that would eliminate overflow. No dice.

Don't be confused by these pictures here. The extra bucket in the picture shouldn't be in use in my set up, at least not from the get-go. The extra bucket was only put in for testing.

hi there sound too complex 4 me, anyway my setup i have 3 buckets for plants 1 bucket for rez 265L/h(water) pump in my rez the tubin for that pump goes to bucket 1 for plants and the water seems to level off

then if i whanted to topup the rez would have a ball valve init and another rez to feed old rez


then if i whanted to drain the system would jus use a 700L/h (water)pump
