When trying to create a new assembly, this error shows...But I am already in the Assembly Sheet of the Complete Parts List

I updated my database and I still get the old valve

Reviewing the results you notice a discrepancy between the k-factor of an equivalent k versus a sprinkler head using that equivalent k-factor

In the example below, EQ02 has a k-factor of 5.37.  Reference point 1 is supposed to use the k-factor of EQ02 (5.37) but in fact is using a different value (5.36).

No error, but when trying to use Add Couplings, Revit stops responding and the couplings are never placed.
