That feels very wrong, using Loctite for something that should be de-mountable. If the mixer will fail and you need to replace it, you have to cut down the pipes and replace them completely. You should think about the next person coming after you..
@@fraserhoehle2256 is there any reason it the valve shouldn't be installed the other way up? Simply because of where my feeds come from, it would be easier to have cold+mix on the top, hot on the bottom.
