All joints are screwed to the pipes. I choose not use glue because of the chemicals. I don't plan on taking it apart anytime soon and its not coming apart on its own! Lol! This is 1 1/4 pipe and is plenty thick and strong for my parrot needs. My local HD doesn't carry that many varieties but doesn't need to. The pvc they do sell is plenty thick! Thanks for the info in either case.
The "glue" used for PVC pipes is a solvent gel. It welds the plastic together. It will not hurt even the most sensitive organism if you let it set overnight so all the acetone has evaporated. My only problem is buying a small enough quantity as I won't use it up before it goes bad. And, for actual plumbing use, the primer stains everything it touches.
I'm asking how you put screws in: what kind of screws, how to they hold in the plastic?
They make clear gel ... no stain. They also make the cleaner and adhesive for use on fish tanks to avoid any potential poisoning hazard.
