I have been using the HN since April and my setup is exactly like the bucket above. Three 2-gal buckets with 3-4 HN each. They have worked perfectly fine and I love them. However last week as the temps dropped to the 40-50s, they all began to leak, but it appears that the buckets are leaking from behind the HN and not the HNs themselves. Is there a contraction issue here or do I need to loosen/tighten them as the temps change or do I need buckets that are not hard plastic.....?

The HN's seal very well by themselves due to their tapered threads. I have not found using teflon pipe tape necessary. When you say, "...but it appears that the buckets are leaking from behind the HN and not the HNs themselves.", are you saying that you think it is leaking where the nipple inserts into the bucket? If so, then here are few thoughts:
* You may have originally over- or under-tightened the nipples. They should be HAND tightened just snugly, not as tight as possible, otherwise they could leak. If you think you over-tightened them, I'm not sure the best route, but you might be able to rectify with teflon tape or new nipples. Or you could drain, clean and dry the buckets and re-install the nipples while using aquarium grade silicone sealant (the aquarium stuff doesn't have toxic chemicals that can leach into the water).
* Check that you installed the nipples square to bucket surface.
* I drill a 3/8" hole to install HN's, which works perfectly. My hunch is that a hole too big or small might lead to problems.
Not sure about the de-icer list above, but I have used this one the last two years and love it. It fits easily into a 3 to 5-gallon bucket:

I removed the float ring so it sits on the bottom of the bucket. This works just great with HN's, but will NOT work with vertical nipples below about 20F, iirc.
I've found starting with smaller than 3/8" drill is the way to goThe HN's seal very well by themselves due to their tapered threads. I have not found using teflon pipe tape necessary.

What material is the bucket, ID or recycle number on the bottom?My horizontal nipples in the white 2.5 gal bucket were perfectly fine from April-Sept....no leakage. I used the recommended drill bit 11/32 and inserted them perfectly square and hand-tightened. It looks like the plastic bucket has cracked above each HN. Maybe I over-tightened them originally but got away with it as long as the days were warm and as the temps dropped the plastic became a bit more brittle.... At this point I don't know if I should just purchase new plastic buckets.
I purchased a 2-gal black rubber bucket today (designed for livestock) thinking that the rubber might be more forgiving than the hard plastic. What do you think?
Also, the submersible heaters that you all recommend specify safety for plastic buckets. What about the rubber buckets?
On a slightly different note from way back in the thread: My 22 hens learned to use the HN within a minute and don't hesitate ever to use them. However, if given the choice, they totally prefer a dish of water.
