Just be sure to use aquarium silicone. Scrogdog and rider run pretty mean rdwc systems. I'll look for links

I had planned on building a system kinda like this one, but instead of the nutes being pumped from the 1.5" tube at the far end of the system back to the rez, I was going to have the pump in the rez and pump it via 1/2" line into that 1.5" tube at the far end of the system.

It would return to the rez via the 1.5" tubing instead of being fed by the 1.5" tubing.

I only desiged it this way because my pump is submersible, not one that can operate outside the rez, and I don't want to buy a new pump right now.

I wonder if this would be an issue, I can only think that the only issue would be if there was a clog from the roots that the buckets might over flow.

Basically, the flow is opposite to what this picture shows.

@Bluenoser your album was set to "album owner only" we (as members) can't see your picture. You may need to make a new album and set it to "members only".

Hopefully someone out there can chime in and let me know if running the flow in reverse will be an issue or not.
I have a feeling if I do that, I'm gonna have to be super diligent about ensuring there are no root clogs otherwise an overflow might occur.
Thoughts?

Well, I've got a 105L rez now, and I've installed the 1.5" pipe in the buckets and uniseals. I've put a bead of aquarium grade silicone around the seals and pipes just to make sure there are no leaks.

I still have to connect the buckets to the rez and install the uniseal in the rez, but after that, and after the silicone has cured I'll be ready to fill it up and see if everything is watertight.

I ended up using poly pipes, the kind used for wells that is labeled potable, there were no 1.5" CPVC potable pipes anywhere in this city, so I bought the poly pipe.

Unfortunately, the poly pipe is not a straight tube, it comes in a large very rigid coil, so, I cranked up the BBQ, and heated the pipe up, just like forging a blade and bent it until it was straight, cooling it with cold water to lock it into shape.
LOL

This pipe was not as snug as the PVC pipe was in the uniseal, so hopefully the silicone will keep thing tight :)
