So, back to wargaming the Beta Site. I was thinking of using Uponor Pex for the basic interior water delivery needs. There are other options, of course, there’s the old-school copper piping which is going to be expensive, require a bit of work to cut and assemble, and isn’t exactly freeze-resistant. Pex, on the other hand, is easy to work with, goes together like Lego, and is less likely to burst if frozen. Additionally, it really adds itself to adding more connections and that sort of thing.
Some plumbing experts I know have been nice enough to answer my questions and show me the various fittings and tools required to work with pex material. We took a piece of Uponor Pex, folded it in half so it had a kink that blocked water flow and then straightened it out. Waved a propane torch over it for a few minutes and the kink completely straightened out to the point that you couldnt even see a sign it was there. And, I am told, the structure of the Uponor Pex is such that when youo heat it up like that, the affected region becomes stronger than what it was before the kink in the pipe.
Connections were made by expanding the pipe and a collar, then slipping the expanded pipe over the connector, and the pex then constricted down to form a seal. The pex, I am told, will have memory that keeps it trying to constrict to its original dimension.
So I got to experiment with cutting, flaring, and otherwise playing with this stuff and its really hard to see a downside. My casual and uninformed opinion is that this stuff, if it lives up to its marketing, is awesome and perfect for my needs – its easy to use, durable, modular, allows for easy modifications, is freeze resilient, and won’t break the bank.
For a small structure, this seems like an ideal way to have an easily maintainable and flexible piping system within the structure. I need to investigate it more, but it seems like a good choice.
