Rusty waterer okay?

I don't have any scientific information on this, but I would err on the side of caution and not risk using rusty waterers. Hopefully, somebody knows more than me and can chime in on this.

 

Sorry-very UNSAFE. The zinc from the finish is now leaching, toxic...not the rust causing probs...

 

I chucked my chicken waterer when it got rusty.

That said, it was probably a stupid thing to do. We used galvanized waterline installed in the 50's for our domestic water for umpteen years, and it was quite rusted out when it was finally replaced. So I'm sure there was PLENTY of rust in the water.

And just look how I turned out. Yeah, chuck the waterer.

 

A galvanized waterer is not supposed to rust. I would take it back to where you bought it and request a new one. I did, and they gave me a new one, no questions.

The whole point of buying galvanized is they aren't supposed to rust, otherwise they may as well make them out of regular steel. I have galvanized buckets that are 20 years old, and there is no sign of rust on them. I think these newer products are some cheap knock-offs from China. More overseas junk.

Love your signature line by the way!

 

Yes, they do rust. I used to soak my chick waterers overnight with vinegar to disinfect. I Unfortunately, the acid removes the coating, and allows it to rust.

I looked it all up last year because I also didn't believe that galvanized could rust.

 

get a heater for plastic waterers. it is an all in one unit I just use the base and place my other wterers on that base because the top piece of the heated unit is just too heavy when filled. ErinM

 

Galvanized steel certainly does rust, this is NORMAL, it's what happens when the galvanized coating is breached. Can happen from scratches, dents, or overuse of acids. (Acids, such as vinegar, are not really a good idea to use in galvanized waterers btw because they can liberate a potentially-toxic dose of zinc from the galvanized coating. Not as bad to use it as a periodic wash than to chronically give them acidified water, but still not a good idea)

Why do some galvanized <whatevers> rust while other ones, purchased elsewhere or at a different time, stay rust-free (so far) under the same treatment? It is because there is galvanization and then there is galvanization. There are different methods of doing it, and differnt thicknesses of galvanized coating. Also if items are thinly galvanized and then treated roughly in shipping etc they can get dings that will let them start rusting almost immediately.

I would not use a galvanized waterer with any appreciable amount of rust in it. You could drill some holes and convert it to a galvanized feeder if you are really demonically intent on getting the last possible use out of it -- that's less of a health risk, as long as there are no sharp rusted-out areas.

Good luck,

Pat

 

Since when are either zinc or rust in water harmful?! All metals are toxic at some dose, but most of the ones you can build stuff out of are not especially soluble in water. (Metals such as sodium, calcium, and potassium are actually pretty dangerous in their metallic form due to their propensity to burn or explode.) Galvanized iron has been used for generations for human water supplies. The biggest problem when it corrodes or rusts is that it creates ugly deposits in the bottom of a pot or on clothing, not because of toxicity.

Zinc metal ingested in chunks can be toxic - a couple of grams can be toxic in humans. However, stomach acid greatly increases dissolution and absorption of the metal. Even somewhat acidic drinking water doesn't carry much zinc in solution in a galvanized container.

LynneP, the zinc from the galvanization is leaching at just about the same rate whether the underlying steel is rusting or not.
