I am brewing this evening and thought I would mount the sight tube on my boiler.
All has gone superbly... but..
the site tube has an elbow that goes on the tdide of the boiler. There is then a threaded nut, a silicone washer and a metal washer.
the threaded section obviously screws into the elbow from the inside but what about the silcine washer and metal washer.One inside and one out, or both on the inside againt the boiler wall??
please help. brew day approaching and I have a hole in my boiler
