Don't you just hate to get those faux brass bolts in a new tank.It is also very frustrating to get copper-plated steel plates for securing copper tubing stubs in between the studs.I hate those chrome-plated steel pipe flanges.Who are they kidding when they tell you it is ok to slide those over copper tubing?!!! Just add urine and watch it dissolve!
Another gripe are the so-called di-electric unions.These are zinc-plated trash and last about five years because of the rust issues.
I have been making my own with a brass NPT x 7/8" compression fitting threaded into a di-electric-fiber-inseted galvanized coupling.They last many years.
I have talked with all of the "usual suspect engineers" at the factories about these issues but only get the "deer in the headlight" looks!!!
