So I got the copper parts last night that I think will take care of my needs. Being "one of those people" who always tries to have a plan B, I also bought a 5' stick (couldn't find any shorter) of RED Pex. I was initially presuming red would be for hot and blue for cold....then looked at the pipe and they both seem to have similar rating so then realized it's probably just to make it an easy visual as you follow the path of the supply you can differentiate between hot/cold lines. (might have prevented my toilet from being plumbed with hot water, which I had to fix a couple years ago)
Anyway... got the stick of PEX. Got what I THINK is a Shark Bite union. I'm going to make a statement but it's actually a question to see if I understand PEX correctly (I've never used it and in fact....never even held it in my hands until last night)
I think I shorted myself on a part. Forgetting all about the copper fittings I bought, I bought a single PEX union. I was thinking (and still am) that I can insert the copper supply line into the union and put the plastic pex on the outlet side and now, I have some wiggle room for my 90 degree with ears that the nipple mounts into.
Except...
I think I should have bought a second union. One to convert from supply copper to pex… then my tubing, then another union to convert from the tubing back to the copper, hard mounted fitting.
Sound correct or am I missing something? (I don't yet KNOW that I can go from copper into the pex union, I'm suspecting I can because of how it's titled on the package....something like "Copper/pex/something other" if I recall my quick scan of it last night.
Won't get time to look at it until later today. If I DO need a second union, then I've got to make a road trip 15 miles back into town.
Love it when that happens.
