The seals are made for 2" pvc. Like 2.375 od. They are a pain in the ass that's for sure. My best advice is to make sure you deburr the ends of your pvc very good, almost round over the outside edge to make inserting it easier. I also wouldn't use any grease to assemble, it will be hard to clean out. A little dish soap on the seal and pipe seemed to work best for me. Lastly, i wouldn't "test" assemble the system then dis assemble. Uni seals will start to leak if you damage them at all.
use bulkheads. it's difficult to get perfectly round holes for the uniseals, and the buckets seem much more prone to splitting over time (from the hole) vs. bulkheads. the container material makes a big difference in success and failure with them i've learned.
tips for uniseals:
-using a drill press helps to get perfect holes.
-a BRAND new holesaw is usually too sharp and will overcut. drill 3-5 holes out in a piece of plywood or something 1st. it's probably the flutes on the side of a fresh one that seem to chow out excess material if you're too aggressive with it. somewhat dull seems to be okay.
-use multiple fine grits of sand paper to finish off the hole, careful as you can easily enlarge/change the hole with low grit.
-use a template from container to container so that your holes are very close to identical. uniseals are less forgiving when you've got some tweak on the pipes going from bucket to bucket.
-use a chopbox saw (with the blade installed in reverse) to make nice, easy, square end cuts on your pipes.
-bevel the ends on a grinder and sand/flatten any sharp edges you create.
-Oatey all purpose pipe lubricant is how i've always gotten them together. messy and needs to be cleaned.
-to take them apart, you can grip the pipe with your pinky thru index fingers on both hands, and push the seal itself with both your thumbs. spin, repeat, and eventually you'll walk it off. it'll be a bit of a fight with 2" but you'll get it. if they sit for a year or two, then that's another story.
-if you get it all together and have tiny/slow leaks, they'll probably stop once you run nutes in it. :D
and more that i've forgotten.. bulkheads are worth the money.
troughs would be a better solution overall.
I put the control bucket on a leg of pvc pipe that keeps it out of the way and makes it accessible and put the chiller outside the grow room. Quite happy with how it is working so far. Thanks!Just a suggestion if u are working with such a small area.. I always hated my first couple CC's i bought as complete the epi is always in the way, so I started ordering them bare bones for multiple reasons and my instinct upon gluing pipes was to flip the tee and put epi inside the system footprint..
in a tent however it is somewhat convenient to have epi conventional setup so u can unzip and barely peek in to check epi and perform maintenance.. I put bricks under chillers so it's not resting on the manifold btw and keeps my whole area hose/snag free
Does anyone have a source for 2" bulkheads like the original ones?I put the control bucket on a leg of pvc pipe that keeps it out of the way and makes it accessible and put the chiller outside the grow room. Quite happy with how it is working so far. Thanks!
What do you mean original ones? I used 2" aquarium bulkheads in the final design. My build log that has photos, instructions and a bill of mateirals is here: https://www.thcfarmer.com/community...formance-under-current-for-300-or-less.94487/Does anyone have a source for 2" bulkheads like the original ones?
Yeah, that was exactly where I ended up.....2" aquarium BH fittings. In my case I got them on Amazon (CPR Aquarium Brand). Cheapo ones on ebay have issues so I recommed the CPR brand.I tried the Uniseals and let's just say, never again. For those who still use them, boil them before trying to install them. You will be amazed how easy they go in. Just make sure you insert your PVC before they cool.
For those of you that want to step up, you should use these bulkheads.
