Bulkhead fittings and threads

I found these 2" PVC bulkheads for a great price ($6.49)
BULKHEADS

From what I read in the description, the part of the bulkhead outside the bucket is slip (glue 2" pvc to it). What if I didn't want to glue the bulkheads? Maybe to allow for dis-assembly. Is it possible to use a female threaded pvc adapter, like this: ADAPTER and screw it on behind the nut?



Are they the same threads and do they seal? Any reason why this would be a bad idea?

All feedback and suggestions welcomed

thx

I appreciate the feedback, but I'm still looking for an answer to the question as to whether this was or was not a good idea. Like I said, I can see how it could be useful going threaded instead of slip, but I'm not sure I've seen any like that. Probably because I never really paid attention until now.

And what I'm referring to, if I haven't explained it well enough is, what are the differences (if any) between gluing pvc into the bulkhead directly or using a 2" female pvc threaded adapter to screw on to the bulkhead right behind the bulkhead's outer nut. Then the pvc pipe would glue into the slip side of the pvc adapter. This would make it possible to reuse the bulkheads on other containers if migrating to a new setup with different dimensions.

WOW, that stuff I just vaped makes me quite chatty LOL

Just use the plummer tape and you will be good. Its fine and wont leak. The pipes under your sink are threaded and dont leak. As for this working on your setup I dont know, you never said what type setup you are doing. Not sure why you need a 2" bulkhead. Most 5gal bucket systems have a 1/2" in and 3/4" out, at least most of what i fave seen.

Sorry

RDWC UC like this...


and these 10 gallon containers:


The big pipe is for the manifold. The one above has 4" pipes, which are overkill

are you sure the walls on those grey ones are thick enough? i've got some for storage and they are pretty flimsy.

i used shower drains in the bottom of my 27 black/yellow totes with 2" PVC pipe

I had seen some set up like this, so I thought they were strong enough. I was originally going to go with the 13 gallon square black buckets similar to the one's above but they were much more expensive. I don't want to save money at the cost of a disaster though.

Is your concern about the container's ability to hold that much water, or are you referring to how we'll the bulkheads would hold up?

would you be against running 2 plants per tote? i used 2 5inch netpots per.
i'd worry about the flexing between the wall of those grey ones and your bulkhead.

the shower drains were in stock at the local hardware store. and about $8 each if i remember. they are just a slip bulkhead. with a metal grate on top (good for keeping hydroton out of the system which i found out later: a bonus)

Did that save you money or have some advantage over bulkheads, or is that just what you went with?
If you go to local backer. Frosting and ice cream come in those square 3, 5, and 8gal. Most places will give them to you with the lid. Saved me a sh**load of cash.

I was thinking about that but was having trouble finding a size where two could fit in my 4x4 tent and have room for pipes. Maybe a 36" to 40". Any suggestions? I like those containers with the yellow lids. Are they 24". I chose the one's I did because they were only 21" and I could easily fit four and hold more water. Did you get your's at HD?

I recently read that smaller netpots with hydroton work better. I forget the reasoning but I think it had something to do with more root exposure. Have you heard about that. I'll look for the post

That's a great idea about the shower drains. I'll def check that out.

Uni seals, some sanding, and gorillia glue work fine.




THIS is what I really wanted to use. What I kept reading was that they were prone to leaking when buckets get misaligned. But it also seemed like the holes weren't done with precision. People mentioned uneven circles and burrs. I am very detailed person and can certainly make some very smooth holes. As well as seal them properly with marine epoxy.

I'm guessing that you took your time with the holes.

You suggested this before and you gave me a link to some awesome prices on uniseals. So, maybe this time I'll take your advice :-)

BTW, it looks like you're using the same containers as rkymtnman. Are they?

So I think it comes down to 4 of these 7.5 gallon 18.0 x 12.63 x 13.25 stacker totes


or 2 of these 50 gallon 39.75 x 21.5 x 17.88 stacker totes


Which would you guys go with (if you would even even go with these)?

Just drill them with a hole saw bit and sand off the burs. The gorilla glue turns to an expanding foam thats waterproof. Its not that hard to be leak proof if you clean up the hole.
