awesome, thanks
where did you buy your bulkheads?

so are we still using 2"abs as return lines still? or are you suggesting upping it to 3"?

I said 3" return line. Black ABS. Bulkheads vary. Amazon is decent, but activeaqua has the best prices on cheaper black ABS. Buy Threaded X Threaded and use 3" Male adapters on the ends of all your return line piping that connects between an all the totes and res. That way it's easy to take apart and clean after each use. The black oil filter wrench from harbor freight make tightening and untightening very simple. Then there's another website you can buy extra rubber gaskets to use on the bulkheads. Somehow I got the 2 I had to work and have never ever leaked but I remember it sucked to finally do it, cause the gasket kept squishing with tightening it. It needed to be thicker. I think wetting it during install would be smart. Silicone or sealant SHOULD NOT BE NEEDED If its done right.
 
This is what I found so far on amazon.ca for threaded bulkheads

I think I'm gonna use the 13g totes for the plants, I have another 40g tote, will that be big enough for res?

I'd grab them quick if they're 3" cause I can't find Shit for 3" cheaper abs bulkheads online. Plenty of 2", but that's it.
Here's a link for replacement gaskets for current culture ones but they take a 3 7/8" hole so as long as the one your looking at requires the same size it'll fit great.
I guess your Canadian though but here it is anyways.

The picture you posted says 2". You could probably get away with 2" if you only use 13gallon totes. The walls have to be parallel to each other.l and perpendicular from the floor. Straight up and down basically to use bulkheads. Keep that in mind. Otherwise you gotta use Uniseals.

Oh nice, I'll order some of those. Tha ks

I seen earlier you mentioned you decreased the size of your pump from 1600gph to 600? I think? Is that size pump still optimal in your opinion? Or would you prefer a different size?

I have 2x 400gph pumps already, one I use in my cloner and the other for my res for hand watering with hose. Wondering which size I would need for 4 sites + res

A 400, would be plenty for only 4 sites on 3/4" to 1/2" fittings.

Ya I'm looking for square/ rectangle totes or buckets as we speak. Those buckets you linked from amazon.com can't be found on .ca and it said it wouldn't ship to Canada.

Or. Yah, just buy the 3" if you want. But 2" will probably do in 13 gallon totes.

You can always buy 4gallon square buckets. See if you can get the 12gal HDX totes up there.

I'm noticing now this bulkhead doesn't ha e threads though so you wouldn't be able to take it apart, ever again. Glue it forever.
I'd just make sure you don't go above 13gal totes and use 2".

Ya I'd be better off with 2" threaded rather than 3" glued forever for sure, and if you say it's fine, I'll just use the 2" and order them right now on amazon.

If I can't find good totes I'll just use the square buckets if I can find them anywhere. I assume Walmart or Canadian tire will have something tho.

Yah,I'd look online more there's plenty of stuff on there. But hardware stores like our home depot are also probably your best bet.
 
Here's the end you want to glue on the ends of all 2" return piping to thread on and off the bulkheads. Use Teflon tape everytime you're putting it together. Plenty of it. And remove old tape before you replace it when putting things back together.

@diggs99 I went with 3inch bulkheads on my 6 site system but I also built a smaller 2 site version for mother plants and I went with 2inch bulkheads. Both working the same no issues with water returning on the 2 site.

Thanks , the 2" are much easier to find and seem a bunch cheaper, AW said for 4 sites the 2" should be fine, so thats probably what ill do.

I have been looking around on hydrobuilder tho, they got some cool shit, might just spend a few bucks and take the easy route haha

Love your build tho bud, i just used the pic when showing another grower what i want to build. Very clean job.
