PVC glue drying time question

[Weyrman]

How long do you folks let your PVC glue dry before hooking things up?

I've just finished putting together a manifold for bleeding excess flow from the return pump into the sump.

I used the "red" PVC glue and I wait about 5 mins. When I installed my sprinklers which has much more pressure than most aquarium plumbing systems, I waited five minutes to test some of my joints. No issues.

For house plumbing, I'd run water as soon as I was finished. For a tank if you apply a lot and think you may have blobs of it at a fitting end, I'd let it dry for 6 hours just to be safe.

You might put some glue on paper and time the drying by touch and smell.

Just my opinion.

Thanks.

I'm more worried about the toxicity of the glue before it dries. How long does it take for toxicity issues to disappear?

I use the blue ones, i think it called christys hot glue...
I usually wait a day to make sure it fully cured. I shortest time was couple of hours. Never had any problems with toxicity.

Depends on the type of pipe and primer/glue. Schedule 40 pvc with purple primer and clear glue cures in less than 24 hours. 24 hours is more than enough of a cure time for reef applications.

I agree, it also depends on how thick of a coat it is and where it is. But 24 hours to be safe in my book. If you have an emergency and only have five minutes, then you got to do what you got to do. Most cases it will seal that fast. If you got the time let it cure.

+1 I usually wait 24hrs unless I had to fix something really fast.

Cool.

Thanks!

I have used the red hot and I do a wet test after 30min and have never had a leak or any issue

24 hours is what I would recommend although most types of glue dries within an hour it's those pockets of excess that is what you need to worry about. Only wet glue that comes in contact with water would cause toxicity issues although I am no expert.

You can run water through a joint 30 minutes after gluing and it won't leak or anything but the primer, glue and pipe are still fusing to one another. You shouldn't have pockets or voids if you're gluing correctly. As far as how thick the coat is, you shouldn't be gobbing the stuff on, it won't make a better seal the more glue you use, in fact the primer is the more important part of the equation, primer is what causes the fusion to take place.

as an ex pool man, PVC glue will dry with in minutes and is good to go by the time you can install it under the tank. I have never had problems with toxicity.

I use cleaner, primer, and clear glue. Clear Oatleys is low VOC and I translate that into less toxic in general. However, it has a longer cure time than most alternatives. The joint is strong enough for the pressure of most reef systems far before I think it is safe to use on my tank. I wait 24 hrs and then soak in water and a little bleach to clean off any greases, oils, or pesticides that might have come with the pieces. Then RO/DI water and old carbon to remove any of the chlorine compounds remaining from the tap water and bleach. Then hang them up and let them dry. I you have the time why not make sure, although, if you don't I would wait until you cannot smell the glue. Clear glue is also more flexible and if you are a tinkerer like myself it is less likely to be compromised when you are working on the plumbing in the future.
