Ray Im not a plumber but one thing you might want to consider is a dielectric union between your brass and steel fittings, or any other dissimilar metals. Looks like you're enjoying your project and that's what makes it worth it!
I don't understand why you are so paranoid about mentioning products. Is it that you want to be paid or expect something in return for mentioning a product/brand? I actually enjoy your videos but find that the most annoying aspect. If you make a beer using a certain yeast, why not mention it so others can benefit/avoid? Just my $.02
+CraigTube I misunderstood the part of you going through your box when you got to the yeast (6:24), I guess you meant to conceal it as a surprise. I thought I had heard you say before you don't like plugging, and I usually unsub when people do that because this is a community of learning from each other, right? If you do get freebies more power to you I think it benefits you and your viewers. I like your content because you are real. Sorry for the misunderstanding.
Unless you are one of their insurance partners, they will shoo you away along with your business. I went there once with an Allstate claim and had good service. I went back as a repeat customer with a Progressive claim and they basically told me to go away. Ill never go back nor will I recommend to anyone.
