Hi All. I'm doing a project using Uponor Propex, and I'm mostly using the EP fittings. I'm doing my project in phases, getting as much ready as I can, and won't be doing the final go-live for another couple of weeks, so I'm not able to test any of my connections, etc. at this point. I have two questions about the EP fittings and would greatly appreciate any answers anyone can provide.
1 - Is it common to be able to "move" the EP fittings in the pex after they're installed? If I apply a lot of force, I can basically twist the EP fitting in the pex. It's not easy, but I can do it. The fittings seem to be in tight in the sense that I can't pull it out of the pex and the expansion ring is right up against the shoulder of the fitting. These are fittings that I let sit for a day or so with the ring on, so it's not like they are "over-expanded" and haven't had a chance to tighten up yet. Has anyone experienced this? Is it anything to worry about?
2 - Why do they say you can re-use a brass fitting but not an EP fitting? As a test, I took one of my EP connections apart using the recommended method: apply heat with a gun, slice off the ring, heat the pex, and pull it off of the fitting. I used a knife and cut the ring off making sure I was cutting away from the fitting so as not to scratch, nick or gouge it. After I did this, I looked closely at the fitting and it looked like new. What is the issue with re-using an EP fitting if you have not damaged it when taking the connection apart? Am I missing something here?
Thanks for your help in advance.
