Hello I had my house re-plumbed with Zurn PEX B tubing and Zurn F1960 expansion rings/fittings.
After verifying all the work, just in one bathroom, instead of Zurn F1960 Polymer/Plastic fittings the plumbers used Uponor F1960 Polymer/Plastic fittings and also mixed in some Uponor PEX A reinforcing rings intermittently (probably got them mixed up in the bucket).
So as an example, in this bathroom I have a coupling joint where it is Zurn PEX B tube on both sides, but an Uponor F1960 coupling fitting, and the F1960 reinforcing ring on one side is Zurn PEX B and the reinforcing ring on other side is Uponor PEX A.
There are no leaks and everything seems very tight.
Obviously, this invalidates the Zurn warranty on these particular joints but I was already knowingly using some non-Zurn expansion fittings throughout the house because Zurn doesn't make certain F1960 items like F1960 stop valves for sinks/toliets and F1960 sillcocks for outdoor faucets. Also, the F1960 brass drop ears the plumbers used for showers aren't Zurn or Uponor but Proflow, which they use on all jobs whether it's Uponor PEX A or Zurn PEX B.
Given this is all made to the F1960 standard should I be concerned? All the inside diameters of Zurn vs. Uponor PEX tubing, F1960 fittings and reinforcing rings are exactly the same. Zurn PEX A and Uponor PEX B tubing have the exact same outside diameter too. Only the outside diameter of the reinforcing rings is slightly different with the Zurn PEX B rings being slightly larger (0.01") vs. Uponor.
While the Uponor PEX A reinforcement ring doesn't have the same "memory" as the Zurn PEX B tubing (i.e. Uponor is greater?), I'd think a PEX A reinforcement ring on a PEX B tube would be fine vs. the opposite--the PEX A ring will retract harder than the PEX B reinforcement ring. I'd think the concern would be the reverse--PEX B rings on PEX A tubing, which I don't have.
The plumber is unwilling to fix this mismatch even for extra $ (claims he's too busy)--and it wasn't spelled out in the contract to use Zurn PEX B vs. Uponor PEX A or to use all the same manufacturer for fittings, it was just a verbal discussion that I wanted Zurn F1960 Expansion PEX B and I just assumed they would use all Zurn fittings except on stop valves and sillcocks.
It was the lowest bid plumber. You get what you pay for.
Thanks!
