Yes, all the connections are cemented together with PVC cement. You see how "curvy" the PVC line is in picture #2 - that pipe is straight in cold weather. Temperature changes cause a lot of flex in the PVC lines, and I have a few leaks to re-glue every spring. Ideally, I guess I should replace all the PVC pipe with threaded metal pipes, but that would be real expensive. Every fall I'm careful to leave ALL the faucets open and of course the water hose is disconnected and put away in the barn then. I don't want ice to break these lines.
The PVC is all 3/4" diameter, the thick supply-line stuff. The faucets are 1/2" and threaded. Hope this helps.
Hey, not relevant to gardening but my long-time fishing and hunting partner passed away this morning after a long illness and I wanted folks to know. He was a good guy - R.I.P. Max!
