Frustrated

I made 2 buckets and a rez and no matter what i do they keep leaking. Ive used aquarium silicone but its the tiniest leak that keeps poking through. They all have seals sigh would of heen cheaper to buy them. The whole t fitting at this point is covered in silicone

Bulkheads and pvc pipe?

No i used seals from lowes....1/² in t barbs and 1/2 clear line.
One bucket is the bubbke bucket. 1 is a control andbi have a 3rd for rez

I was trying to offer that as a solution. The barbed elbows that came on my bucket even leak. How much wiggle room does the barb have going into the bucket? Do you have a gasket along with silicone?

This will help a little better than silicone. Needs a 3/4 inch hole. And will fit your half inch barb

It had wiggle room so i covered the bard with the 1/2 tubing and slid it back in. Then sealed the back and front with aquarium silicone....i didnt use a gasket just a seal

Are you using silicone to seal the other end of that T coupl

Rubber grommets like this are designed to run cables and the like through, not for sealing a water tank line.

You're going to have to purchase some proper fittings and seals. Patching with silicone will not be reliable, and when you're in week seven of flower, you definitely don't want to accidentally move a bucket and spring a leak... or worse, spring a leak when you're not home.

Pics? I find that an odd use for that type of grommet. Where did you get your buckets from?

I get home tomorrow I can take a pic then? I could have also looked at the wrong ones

You need bulkhead fittings.

Will this work
Using these grommets
Along with these valves

Amd these tubes


Or will i need something else.
I was trying to find a 1/2 female threaded pipe i could put through the seal like this and connect to this instead

I would do the half inch threaded bulkhead to the barb so you can use your tubing. Is the tubing for ease of movement?

Those grommets seal water out like bone other man. I've built copious setups using 1/2,3/4,&1" they all hold water tight with the hydro flow barbed fittings

Uniseals will work for sticking a whole 1/2" PVC pipe through. The donut grommets are made for 1/2" hydro flow barbed fittings to then connect black vinyl tubing to. Not PVC.

This is all the wrong stuff. You needed a 3/4" grommet, a BLACK hydro flow 3/4" tee. 3/4" black hydro flow tubing and a 3/4" barbed ball valve.

Yes its a small 2x2 why what do you suggest

Well after this grow I'm going to be doing an rdwc. And mine are going to be set up so I can't move them around. Plus they are going to be 27 gallons each. Whats the whole setup look like?

The system il trying is a 5gallon bucket res ontop of a 5 gallon control bucket. Control bucket connect to res with a float valve and gravity. Control bucket to dwc same height no pumps


The res and control are outside the tent
