I have had horrible luck with these things. I tired a homemade one first that didn't work then bought a galvanized metal one that leaked like a seive. I got a 3 gal plastic one from TSC and it did good the first time but now I can't get it to stop leaking.

I'm going to try an old scuba diving trick and put vaseline on the O ring.

Any other suggestions?

Vaseline didn't work for me, But I did find out what does. The O-ring that you get with it is the wrong size.
I ordered a #421 o-ring from Mcmaster Carr and that fixed it.
select #421 from the "select AS568A Dash Number" drop down list.

The food grade silicone is the cheapest at 9.12 for a 5 pack.

or type "9396K932" in the search at the top left.

ETA If you call to order a real person answers and they can tell what shipping will be. They don't tell you what shipping will be online, but it won't be much for a pack of 0-rings. They ship fast too, get your order right the first time, you won't get the chance to change it before they box and ship it.

Thanks! How did you know for sure which one I had? I didn't look around that much, they must only carry 1 kind. Anyway, I'm calling them today.

The only other 3gal waterer they have does not use O-rings.

I have one from TSC(round) and another brand(octagon) , they both take the same size O-ring. The threads for the lid are the same size too. It will be snug but it won't leak.

To tell if the O-ring is the right size. The outside diameter of the O-ring should be slightly smaller than the inside diameter of the lid where it seals. It will stretch over the neck. The O-ring that came with my water was a 3/16" /4.5" OD. The one that fixed it is 1/4" /4.5".OD. Its just thicker to give more sealing area.
