Yes what you want is 3m marine adhesive sealant 5200,it's a marine grade silicone used below waterline on boats the depot or Lowe's have it.

Theres a jbweld thats safe for water pipes and will set under water.

[LuccaDaddy]

Not sure what you mean...well, got a pic of that ...tube or whatever? Thanks for the input brother

 

[DrMcSkunkins]

I was just sayin it says safe for drinking water so it should probably be safe for rez
Its putty, you squeeze it and then put it on whatever you want to stay put, better than glue.

Is it food grade? Im obssessed with healthiness as im doin this at this level for my Fathers bloodpressure....drops it down to a solid 120-130/80ish.....gotta make sure its not gonna give any bad stuff....id remove more junk from the water if I could, but I get my ppm about 60-80ish befor nutes or pH adjustment

JB would work but 5200 will stay flexible after it cures and temperature variations won't affect it.
It's just a res so I guess they would both work but no way JB will hold up like 5200.

Why use caulking? if they're installed correctly there's no need to use it. They come with rubber washers, but if that didn't work I would get the right sized grommet to seal it off rather than any type of caulking

 

[LuccaDaddy]

Hahaha oh shit, your totally right bro. Hahaha im an air head hahaha thats great

 

[LuccaDaddy]

Make sure you mix it well! Or it will not set. I had an issue that got really wet really quickly because of this.

I actually prefer JB Clear Weld, personally I had better success with it.

Thanks man, dont think I will need it now, forgot ice probe came with gaskets

My issue arose when I got a larger bulkhead to put on a round container and the curvature prevented it from sealing, leaked everywhere. Then I Water Welded the shit out of it and let it sit over 24 hrs and it never fully hardened and ripped right out. So I used Clear Weld. Had to use a lot of it as it's much thinner. But it gets all in the cracks and forms a real nice seal.

That was my experience at least :) largely caused by operator error! Are the buckets you are putting bulkhead on square or circular? If circular does the bulk create a tight seal?

 

[LuccaDaddy]

Nah man they are squares this time. Got it all setup. Will post pics tommorow after I set timers. Check my grow diary GrandDaddy Purp rdwc yaaa!

 

[LuccaDaddy]

Thanks for info though bros, definatley know what to do if I ha e any trouble

I was out of clear weld and used some water weld last night. When you're kneading it you can almost feel the moment when it mixes correctly. It becomes much more pliable and soft.

 

[DrMcSkunkins]

Im not sure if its a chemical reaction or just the act of mixing it up but I think it gets warm when its good snd mixed.
