Can you please post a picture of the product you used?
Also read on the bottle/tin for instructions and ingredients or look for a web site that will give information on the product.
I found this through google
Henkel.com
I'm not sure if you talking about wood glue or some other kind of glue, I think you have used some other kind of glue which is not wood glue especially the fact that you have glued on PVC piping, glue has to be strong to stick to PVC piping, the water proof wood glue is non-toxic and does not have a strong odor and would not have stuck to PVC piping.
