Product review (4 stars): This is the second Symmons package that I found like this. Before you start work on your valve
These are the genuine parts. However, Symmons has a problem with some of their packaging; the seal was open on the little bag these came in, and three pieces were missing (thanks, Amazon, for replacing them!). This is the second Symmons package that I found like this. Before you start work on your valve, count your parts!
