I used these 3/4" Uniseals to attach 3/4" PVC pipe to 2 gallon and 5 gallon buckets to run my poultry cups to various places in the run and coop. Found them at bulk reef supply with free shipping for a little over $2/ring.

You do need a hole saw in order to make the hole in your bucket. If you have an electric drill but no hole saw bit (need 1 and 1/4 inch hole, I think), you can find a bit that will make the perfect hole for $7-10.

Once the hole saw has done its job (done in seconds), all you have to do is push the Uniseal through the hole, then put your 3/4" PVC pipe through the Uniseal hole.
No leaks, no caulk, no tape- NO leaks. I chose to put mine in the side of the buckets- should work for bottom of bucket too.

The only thing that was a little hard was putting the PVC through the Uniseal hole, but that's a good thing, and that's why you don't have to use any caulk or tape.

I used two Uniseals for each bucket- one that feeds the watering cups, and the other acts as a drain for the bucket with a PVC ball valve so I never, ever have to pick up and invert anything.
If you want to remove the bucket for cleaning without moving PVC pipes with poultry cups/nipple system (picture was taken before cups were installed in PVC pipe), just pull the 3/4" PVC out of the Uniseal (after it's empty, of course), clean, push it back through the hole, refill.

Not so much as a drop lost through the Uniseal, but I imagine the hole saw is key to this result.

I got 12 of these off Amazon for around $30. Would not waste money on the 5-packs that come with special attachments etc. All you need is a 3/8" drill bit (double check the directions for drill bit size), 3/4" PVC pipe and 1/2" plumber's tape ($1). I don't know that I would put these directly into a bucket- not sure if the bucket side is thick enough for the threads to get a good hold.

Watering is so much more peaceful with these cups. No more beaks beating on nipple waterers to get a few drops. All I had to do was fill the cup once for the chickens and they picked up how to use it immediately. They almost can't help but touch the trigger when they go to drink. When a bunch decide to drink from the same cup, using 3/4" PVC pipe, there's more than enough water to go around with 5-6 hens going for the same cup in rapid fashion. They can dip their wattles in to cool off a bit.

Our 2-3 week old broody raised chicks were working these things by themselves by jumping onto the PVC and working the top of the trigger with their tiny beaks, filling the cup drinking from it. The trigger moves all ways so it doesn't matter how the chick/en decides to move it, it will fill, and it is sensitive to touch. Eventually they seem to learn how to drink their fill and leave the cup dry which is nice for hygiene.

Have one system inside, one outside, keeps bedding dry, no issue with leaks - did use plumber's tape on the threads. Your imagination is the limit in terms of how you choose to set them up.

Do recommend putting a PVC ball valve on the end of the PVC pipe so you can drain the contents quickly and easily without moving anything- easy to drain that way if freezing weather comes and it's an outside situation that will freeze, easy to clean that way, and flush any warm water out of the pipe on hot days.

Got this as a gift. Hooked it up to a 5 gallon bucket because I hate leaving hoses on.
Not sure how long I dinked around with this piece of junk but no matter what I did it leaked and leaked and leaked some more, draining the 5 gallon bucket in an unacceptable amount of time. I'm generally good at figuring these things out, read the directions, looked on youtube, did everything you can do to this design and it was a huge water waster.
The only positive thing I can say is it has a nice capacity for lots of beaks. But the flip side to this is it is probably deep enough to drown a little chick if left in place- not something I learned the hard way, but should be considered if using around broodies with babies.
