Apologies for the tardy reply - I was off on vacation last week. I am very sorry to see that you have had issues with your Etha Valve system. Very early Etha Valve Bodies (the first few hundred units) featured a dimension that proved to be inadequate, so as such we will gladly send you any replacement parts that you require.
All that i need you to do is ensure that your marker is registered for warranty via:
Once you have done this, please contact Gerry Bates at our Rhode Island office on either (401) 2479061 or firstname.lastname@example.org
and he will gladly get you sorted out asap.
We have since modified the dimensions of the Etha Valve body to strengthen thsi area and as such this was a rolling revision introduced into our production very early in Ethas history.
