So I made a dip tube out of copper today but I had a few questions. Is it ok to use faux and silver to make the diptube? I assumed it was because thats what plumbers use (and the guy at lows said so) but i wanted to make sure. Came out pretty well and the best part is it works! Also I dont want to keep screwing and unscrewing the diptube out of the kettle so is it ok to just suck some hot water/pbw through it at the end of the brew day and just let it be?
