Anyone using a DIY pipe overflow?

[daniella3d]

I just build one for my nano and I want to know if anywone have been using this with success or with horror stories?

So far I have tested it in a bucket and it is working great. I will probably build a second one to be safer in case the first one would get blocket by something.

Here is the design I built with CPVC and glued it with CPVC glue. How long do I need to cure this in water so that it will be safe? It is safe for human drinking water but I am a bit afraid for the aquarium?
