I want to put a spigot on a 55 gallon plastic food grade barrel for my RO water. Would a regular bulkhead work or would a uniseal be better? Thanks

Bulkhead!!!! That is what I used and you will be able to screw the spigot into it.

What if you wanted to put it on the side of the drum...Could you still use the bulkhead with the curve of the drum or would a uniseal have to be used in this case? Thanks!

I have 5 different drums being used for sumps, 2-part mix, RO storage and saltwater storage right now and have used Uniseals for all of them. Never had a leak and easy to use. You could probably stick a bulkhead into the side and crank it down but why bother when Uniseals are designed for that and a couple bucks cheaper?

I was going to put it on the side but you guys are suggesting on the end with a regular bulkhead? Then have the barrel lay on it's side? The barrel has two holes on the top if that affects the decision at all.

I use uniseals for a lot but have trouble with them on thin. flexible material such as the 44g Brute. Don't recommend them for that type of application.

I put bulkheads in the sides of my 55 gal barrels. I originally wondered if they would leak due to the curve, but it is not that dramatic in this size of a barrel and none of them have leaked. With smaller barrels, such as a 30 gal, that might be a different story, but with the larger ones I would definitely go with a bulkhead. If you wanted to put it in one of the ends where the holes already are, you can get an adapter to screw into the hole that is there that you can screw the spigot into.

Like has been said, you could use a uniseal, but I would think it would be hit of miss whether they would leak. With a bulkhead you know it won't leak.

I haven't had one leak yet out of the 15 or so in my system. Maybe you guys aren't using the proper size hole for your Uniseals. They are designed to hold pressure whether it is air or liquid and not leak at all.
