How long should PVC glue dry?

  • We are currently upgrading MFK. thanks! -neo
I usually wait 15 mins from the time I locked the pieces in place. I have not had trouble with it except when I was working in tight quarters and couldn't turn the pipes properly, that was quickly fixed with extra "external" application of the glue/cement.

Probably the same way I do! Oh, it was the nastiest experience EVER! Well, maybe not as nasty as watching a certain video about two young ladies and their cup. :irked:

Oh, tell me about it! I will never again be able to eat peanut butter (especially chunky peanut butter) ever again!
 
I have used it as little as 2 minutes multiple times, just the glue, just the primer, and also just primer and glue and never once had a problem. I have on a couple occasions got the fumes in my lungs.

I think pvc glue/prime is a joke for aqarium use, I have used prime then glue like your supposed to, just prime, and few times just glue; I ran out of one or the other. A all of them are still bonded to this day. So now I only buy the glue, I was only buying primer since it was cheaper, but I don't like the purple stains.

Well, I glued all the PVC pipes for the overflow together, and I was wondering how long it should dry for it to be safe for aquarium use. 24 hours? 48?
So, back to the question, how will I know when it's aquarium safe?

Technically the pipes are bonded with a couple of seconds. You can even run water through them within a few minutes. However, if there is going to be any kind of pressure in the system, you want to wait at least 2 hours. This is about how long it takes for the pvc to be fully bonded and "inseparable" after being glued.

I learned this the hard way when I re-plumbed my water heater... Pipes bursting under pressure coming from a hot water heater are not fun to deal with when you're in a 24" crawlspace...

The air TASTED bad (yes, I could taste it) and it burned the back of my throat and I was coughing and sputtering and gagging for about 10 seconds. It was nasty! I learned my lesson, I guess.

I tried it a couple of hours after sealing some pvc pipes for my water change plumbing. I was unpleasantly surprised by just how bad the air tasted.
