Hi Ironraven

A quick question. How does this pipe stand up to the cold? It gets up to -50 in the winter here so the plastic may shatter if dropped. I imagine this type of pipe would hold up well under that kind of cold but I don't know.

I like your design. Very well thought out. I think I may give it a try using the caps that thread on the outside of the pipe. It may make it easier to remove the cap in the cold/wet.

Thanks for the tips
